谦卑若愚，好学若饥，吾异无他，唯手熟尔！ 一个不断追求完美的少年--晨曦Dawn
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 一。需求： 本篇博客是最近笔者做的一个项目，已经上线但是还在不断开发，有些页面上的配置，测试服务器和正式服务器的参数不同，需要经常改动，所以直接改页面肯定不合适！ so;产品经理提出一个需求，需要只建一个配置文件，存储正式服务器和测试服务器的配置，要求前后台通用，读取方便，修改方便 二。结构： 采用.json文件实现的前后台通用读取 三。知识点： 前后台不同的.json静态文件读取，解析方式 编写能让springboot识别到自定义静态资源的路径的插件 四。优点： 比.js，.properties文件，以及多次请求后台的静态.class文件要优良一些，无论从性能还是被浏览器缓存Gank的因素来讲，这个.json的方式确实优良 五。方案思路以及最后解决： 1.项目结构 2.创建.json文件---->TheServerURL.json 注意：里面的格式为json { "appId": "123456", "secret": "123456789123", "url61": "http://192.168.1.1", "urlhead": "baidu.com", "urlinit": "www.hao123.com", "urlman": "mi.com", "justChangeThisURL":"https://www.cnblogs.com/DawnCHENXI/" } 3.给springboot注册插件ApplicationConfig，让他识别到放置于resource下的静态资源（.json放在此处是因为修改方便，打成war包之后，它很好找） package com.xy.config; import org.springframework.context.annotation.Configuration; import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry; import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter; //这个注解需要启动类去设置一下，否者不会识别 @Configuration public class ApplicationConfig extends WebMvcConfigurerAdapter { @Override public void addResourceHandlers(ResourceHandlerRegistry registry) { /** * 如果我们将/xxxx/** 修改为 /** 与默认的相同时，则会覆盖系统的配置，可以多次使用 addResourceLocations 添加目录， * 优先级先添加的高于后添加的。 * * 如果是/xxxx/** 引用静态资源 加不加/xxxx/ 均可，因为系统默认配置（/**）也会作用 * 如果是/** 会覆盖默认配置，应用addResourceLocations添加所有会用到的静态资源地址，系统默认不会再起作用 */ registry.addResourceHandler("/**") .addResourceLocations("classpath:/META-INF/resources/") .addResourceLocations("classpath:/resources/") .addResourceLocations("classpath:/static/") .addResourceLocations("classpath:/public/") .addResourceLocations("classpath:/"); registry.addResourceHandler("classpath:/mybatis/**"); super.addResourceHandlers(registry); } } 4.前台页面的使用方式（需要jquery支持） function test() { var dataroot="/TheServerURL.json";//json文件路径 var urlTemp; var appid; $.getJSON(dataroot, function(data) { urlTemp = "http://"+data.justChangeThisURL+"/teacher100/skip/login" appid=data.appId var path = "https://open.weixin.qq.com/connect/oauth2/authorize?appid="+appid+"&redirect_uri=" + urlTemp + "&response_type=code&scope=snsapi_userinfo&state=123#wechat_redirect"; window.location.href = path; }); } 5.后端构建个工具类，用来承载前端传回来的值（TheServerURL ） package com.xy.model; public class TheServerURL { //测试服务器 public static String urlhead=""; public static String urlinit=""; public static String urlman=""; public static String appId=""; public static String secret=""; public static String url61 = ""; public static String justChangeThisURL=""; public static String getJustChangeThisURL() { return justChangeThisURL; } public static void setJustChangeThisURL(String justChangeThisURL) { TheServerURL.justChangeThisURL = justChangeThisURL; } public static String getUrlhead() { return urlhead; } public static void setUrlhead(String urlhead) { TheServerURL.urlhead = urlhead; } public static String getUrlinit() { return urlinit; } public static void setUrlinit(String urlinit) { TheServerURL.urlinit = urlinit; } public static String getUrlman() { return urlman; } public static void setUrlman(String urlman) { TheServerURL.urlman = urlman; } public static String getAppId() { return appId; } public static void setAppId(String appId) { TheServerURL.appId = appId; } public static String getSecret() { return secret; } public static void setSecret(String secret) { TheServerURL.secret = secret; } public static String getUrl61() { return url61; } public static void setUrl61(String url61) { TheServerURL.url61 = url61; } } 6.注册插件，在启动项目的时候读取配置（这个可以之后再去拓展，或者再写接口，实时刷新） package com.xy.config; import com.alibaba.fastjson.JSON; import com.xy.model.TheServerURL; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.core.io.ClassPathResource; import java.io.*; import java.util.HashMap; @Configuration public class TheURLLoadBean { public TheURLLoadBean(){ try { //读取到静态资源文件 org.springframework.core.io.Resource resource = new ClassPathResource("TheServerURL.json"); File file = null; file = resource.getFile(); //使用io读出数据 BufferedReader br = new BufferedReader(new InputStreamReader(new FileInputStream(file))); String str = null; StringBuilder all=new StringBuilder(); while((str = br.readLine()) != null){ all.append(str); } if(all!=null){ //采用阿里的fastjson解析这个json HashMap hashMap=JSON.parseObject(all.toString(),HashMap.class); //装配给这个工具类的静态字段 TheServerURL.urlhead=(String) hashMap.get("urlhead"); TheServerURL.urlinit=(String) hashMap.get("urlinit"); TheServerURL.urlman=(String) hashMap.get("urlman"); TheServerURL.appId=(String) hashMap.get("appId"); TheServerURL.secret=(String) hashMap.get("secret"); TheServerURL.url61=(String) hashMap.get("url61"); TheServerURL.justChangeThisURL=(String) hashMap.get("justChangeThisURL"); } } catch (IOException e) { e.printStackTrace(); } } } 7.后端使用配置文件的参数（直接用这个 工具类类名 . 静态字段名 ）就可以调用到 TheServerURL.appId 笔者：晨曦Dawn 转载请注明出处！ 如果有错误或疑惑，请您指出，互相探讨互相学习，感激不尽！！！！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 我的博客即将入驻“云栖社区”，诚邀技术同仁一同入驻。
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客给刚接触存储过程的朋友做个引导作用，目的是解决游标不走循环 很多人发现他的游标，无论是嵌套循环还是单层的循环，都不会走，或者只走一次，但是从数据上看它并不应该走一次，我把结论给大家说一下 很多人都有这俩行中的一行 DECLARE CONTINUE HANDLER FOR SQLSTATE '02000' SET done = 1; DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1; 它的作用是什么呢？ 就是在下面的执行过程中，一旦有空记录（就是没有返回结果），或者一旦有异常，就会把done设置为1，你循环的时候，判断的done。所以就会出现循环不走的问题 解决方案： 1.异常的话需要自己排掉 2.如果是嵌套循环，需要在内层循环结束后加上一个 set done=0; 3.如果你在循环内或者循环前还查了东西，而它没有记录返回，它也会把done改为1，所以，如果你不能删掉那条查询语句的话，就得在后面 set done=0; 大致意思就是这样，可以去尝试一下！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客要讲的有，如何创建一个唯一的文件名，创建一个唯一的String字符串 为什么要创建唯一呢？再很多情况下，比如文件上传，文件名要不一致，否则就覆盖掉了，如何不一致，这就是本篇博客要讲的内容 注：直接采用随机数是愚蠢的做法，它在很大概率上会有相同的数字出现 方式一：时间戳 推荐指数： 原因：时间戳在高并发情况下有可能会出现相同 解决方案：再拼随机数，注意拼接的时候别让俩个做加法运算 时间戳变量+""+随机数变量 //时间戳第一种 System.out.println(new Date().getTime()); //时间戳第二种 System.out.println(System.currentTimeMillis()); 随机数： //生成六位随机数 System.out.println((int)((Math.random()*9+1)*100000)); 方式二：微秒数 推荐指数： 原因：它比时间戳还要细，控制的力度更强 也可以加随机数或者自己拼接自己的规则 //微秒数 System.out.println(System.nanoTime()); 方式三：UUID 推荐指数： 原因：他是java.util包下的一个可以产生不同的字符变量的一个类，它的功能很强大 //采用UUID的方式 import java.util.UUID; UUID randomUUID = UUID.randomUUID(); System.out.println(randomUUID); 方式四：在前三种基础上自定义规则 推荐指数： 原因：在日常中上面三种都足以满足自己的小Demo，小项目使用，但是在成熟大项目中，或许有些不够看，所以，我讲第四种 思路：文件名不是一个字符串嘛，做拼接的三面三种方式任意一种的时候，可以自己加入自己的规则，比如上传者的id，比如你从那块上传的解释，甚至加入8位甚至更多的随机数等 就是自定义规则，让概率变得更小！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本次记录如何设置CefSharp忽略安全证书，以及他的一些其他配置 参考网址： https://peter.sh/experiments/chromium-command-line-switches/ 这个网站记录了CefSharp所有可以设置的配置 http://www.codebye.com/cefsharp-help-2-config-manage.html 这个网站记录了如何具体设置，不过第二个网站在刚才测试中好像没能打开，我简单说一下 具体设置 我在第一个参考网站中找到证书，他有俩个，我不知道哪个起作用，我就都配置了 //安全证书 settings.CefCommandLineArgs.Add("--ignore-urlfetcher-cert-requests", "1"); settings.CefCommandLineArgs.Add("--ignore-certificate-errors", "1"); 这是flash的配置 //flash settings.CefCommandLineArgs.Add("ppapi-flash-path", AppDomain.CurrentDomain.BaseDirectory + "\\Plugins\\pepflash\\pepflashplayer.dll"); 具体放入的位置，参考我上篇博客的InitializeCefSharp方法里，我写个Demo /// <summary> /// 解决anycpu不能兼容 /// </summary> [MethodImpl(MethodImplOptions.NoInlining)] private static void InitializeCefSharp() { var settings = new CefSettings(); // Set BrowserSubProcessPath based on app bitness at runtime settings.BrowserSubprocessPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, Environment.Is64BitProcess ? "x64" : "x86", "CefSharp.BrowserSubprocess.exe"); //安全证书 settings.CefCommandLineArgs.Add("--ignore-urlfetcher-cert-requests", "1"); settings.CefCommandLineArgs.Add("--ignore-certificate-errors", "1"); //settings.CefCommandLineArgs.Add("allow-http-background-page", "1"); //settings.CefCommandLineArgs.Add("allow-insecure-localhost","1"); //settings.CefCommandLineArgs.Add("allow-http-screen-", "1"); //settings.CefCommandLineArgs.Add("reduce-security-for-testing", "1"); //flash settings.CefCommandLineArgs.Add("ppapi-flash-path", AppDomain.CurrentDomain.BaseDirectory + "\\Plugins\\pepflash\\pepflashplayer.dll"); // Make sure you set performDependencyCheck false Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler: null); }
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客讲述如何在AnyCPU模式下使用CefSharp 因为在某些情况下，不得不用AnyCPU，但是CefSharp支持的是86和64位俩种模式，所以在我查阅了很多国内外的资料下，总结出来的一些精华 参考地址： https://ourcodeworld.com/articles/read/173/how-to-use-cefsharp-chromium-embedded-framework-csharp-in-a-winforms-application https://github.com/cefsharp/CefSharp/issues/1714 https://github.com/cefsharp/CefSharp.MinimalExample/blob/demo/anycpu/CefSharp.MinimalExample.Wpf/App.xaml.cs 三篇结合就可以实现在AnyCPU下使用CefSharp 简单步骤记录 第一篇博客取其第二个，更改配置的那一块，这块不改，下面的没用，项目起不起来 简述一下： 1.修改为首选32位， 2.在你项目名.csproj文件下，加一段 <CefSharpAnyCpuSupport>true</CefSharpAnyCpuSupport> 位置如下： 3.在App.config下加一端 <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <probing privatePath="x86"/> </assemblyBinding> </runtime> 位置如下： 第二篇博客取的精髓在这块，我给放过来 public partial class App : Application { public App() { //Add Custom assembly resolver AppDomain.CurrentDomain.AssemblyResolve += Resolver; //Any CefSharp references have to be in another method with NonInlining // attribute so the assembly rolver has time to do it's thing. InitializeCefSharp(); } [MethodImpl(MethodImplOptions.NoInlining)] private static void InitializeCefSharp() { var settings = new CefSettings(); // Set BrowserSubProcessPath based on app bitness at runtime settings.BrowserSubprocessPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, Environment.Is64BitProcess ? "x64" : "x86", "CefSharp.BrowserSubprocess.exe"); // Make sure you set performDependencyCheck false Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler: null); } // Will attempt to load missing assembly from either x86 or x64 subdir // Required by CefSharp to load the unmanaged dependencies when running using AnyCPU private static Assembly Resolver(object sender, ResolveEventArgs args) { if (args.Name.StartsWith("CefSharp")) { string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll"; string archSpecificPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, Environment.Is64BitProcess ? "x64" : "x86", assemblyName); return File.Exists(archSpecificPath) ? Assembly.LoadFile(archSpecificPath) : null; } return null; } } 第三篇博客 就是告诉你using指令怎么引，以及详细的写法，要用的话，还是用第二篇博客的这段代码 using System; using System.IO; using System.Reflection; using System.Runtime.CompilerServices; using System.Windows; namespace CefSharp.MinimalExample.Wpf { public partial class App : Application { public App() { //Add Custom assembly resolver AppDomain.CurrentDomain.AssemblyResolve += Resolver; //Any CefSharp references have to be in another method with NonInlining // attribute so the assembly rolver has time to do it's thing. InitializeCefSharp(); } [MethodImpl(MethodImplOptions.NoInlining)] private static void InitializeCefSharp() { //Perform dependency check to make sure all relevant resources are in our output directory. var settings = new CefSettings(); settings.BrowserSubprocessPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, Environment.Is64BitProcess ? "x64" : "x86", "CefSharp.BrowserSubprocess.exe"); Cef.Initialize(settings, performDependencyCheck: false, browserProcessHandler:null); } // Will attempt to load missing assembly from either x86 or x64 subdir // Required by CefSharp to load the unmanaged dependencies when running using AnyCPU private static Assembly Resolver(object sender, ResolveEventArgs args) { if (args.Name.StartsWith("CefSharp")) { string assemblyName = args.Name.Split(new[] { ',' }, 2)[0] + ".dll"; string archSpecificPath = Path.Combine(AppDomain.CurrentDomain.SetupInformation.ApplicationBase, Environment.Is64BitProcess ? "x64" : "x86", assemblyName); return File.Exists(archSpecificPath) ? Assembly.LoadFile(archSpecificPath) : null; } return null; } } } 三套组合拳打完，CefSharp就可以在AnyCPU模式下使用了
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 首先我讲明一下我要做的，公司有个C# wpf的项目需要我把一个开发好的网页嵌入到客户端当中，由于种种原因，我放弃了ie，转而选择了CefSharp 本篇博客会讲如何安装CefSharp，未来几篇博客将会把我所遇到的问题，包括如何忽略安全证书，如何在anycpu模式下使用CefSharp等种种我踩过的坑都讲述一遍 安装CefSharp步骤一:进入NuGet管理 安装CefSharp步骤二:搜索并且下载 安装CefSharp步骤三:配置管理器 此处可以配置成86或者64位的，但是我的项目做过一些手脚，所以只能是Any CPU，但是正是这样，恰恰出现了问题 步骤四：空跑项目，测试报不报错 大部分情况下都是没有问题的，所以安装成功 我的因为是any cpu，所以出现问题，我下一篇博客来详细讲
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客讲述几种跨域发HTTP请求的几种方法，POST请求,GET请求 目录： 一，采用JsonP的方式（只能是GET） 二，采用CROS的方式（需要在接收的一端也有配置） 三，采用form表单的方式（有些时候会存在问题，一会详细说明） 四，采用代理网站帮忙转（不推荐，不安全，性能低，不做解释) 五，后台JAVA后端通过net方式发送 一，jsonP的方式： $.ajax({ url: "http://localhost:9090/student", type: "GET", dataType: "jsonp", //指定服务器返回的数据类型 success: function (data) { var result = JSON.stringify(data); //json对象转成字符串 $("#text").val(result); } }); 它只能发送get请求 二，CROS的方式：（需要接收的一端也配置） 1.发送处： $.ajax({ url: "your url which return json", type: "POST", crossDomain: true, data: data, dataType: "json", success:function(result){ alert(JSON.stringify(result)); }, error:function(xhr,status,error){ alert(status); } }); 2.接收处： response.addHeader( "Access-Control-Allow-Origin", "*" ); response.addHeader( "Access-Control-Allow-Methods", "POST" ); response.addHeader( "Access-Control-Max-Age", "1000" ); 三，采用Form表单的方式提交，（可以实现POST跨域请求） 把数据封装成form表单中的字段，然后发送过去 不好的点：加入你在form表单提交的过程中，这个新增弹窗被代码给直接关掉，有可能的是它没有传过去 function crossDomainPost() { // Add the iframe with a unique name var iframe = document.createElement("iframe"); var uniqueString = "CHANGE_THIS_TO_SOME_UNIQUE_STRING"; document.body.appendChild(iframe); iframe.style.display = "none"; iframe.contentWindow.name = uniqueString; // construct a form with hidden inputs, targeting the iframe var form = document.createElement("form"); form.target = uniqueString; form.action = "http://INSERT_YOUR_URL_HERE"; form.method = "POST"; // repeat for each parameter var input = document.createElement("input"); input.type = "hidden"; input.name = "INSERT_YOUR_PARAMETER_NAME_HERE"; input.value = "INSERT_YOUR_PARAMETER_VALUE_HERE"; form.appendChild(input); document.body.appendChild(form); form.submit(); } 四，采用代理（不安全，性能不好，所以不讲） 五，采用后台发送（Java的net） 注意的点：不要在事务开启的那层发，有可能你发数据的时候还没持久化到数据库，所以接收的那一端没有 package com.xy.aider;

方式一、使用ServletActionContext（耦合度高，不建议使用） public String login(){ ServletActionContext.getRequest().getSession().setAttribute("user","王彬"); return "success"; } Struts.xml <action name="login" class="cn.xcq.entity.Action1" method="login"> <result>/success.jsp</result> </action> Success.jsp <%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %> <html> <head> <title>Title</title> </head> <body> <h1>成功页面</h1> ${sessionScope.user} </body> </html> 方式二、实现接口 这个案例使用session作用域，所以实现SessionAware接口 Struts2底层将作用域都封装成了Map。 public class Action1 implements SessionAware { //声明一个Map private Map<String, Object> session; //使用session需 实现sessionaware接口 //requesr RequestAware接口。。。。 public String login(){ session.put("user","程高升"); return "success"; } //重写SessionAware的setSession方法，将声明的session赋值给它 @Override public void setSession(Map<String, Object> map) { this.session=map; } } Success.jsp <%@ page contentType="text/html;charset=UTF-8" language="java" isELIgnored="false" %> <html> <head> <title>Title</title> </head> <body> <h1>成功页面</h1> ${sessionScope.user} </body> </html> 方式三、ActionContext //方式三 public String login(){ //session Map<String, Object> session = ActionContext.getContext().getSession(); session.put("user","林帅"); //request Map<String, Object> request =(Map<String, Object>) ActionContext.getContext().get("request"); request.put("name","程高升"); return "success"; }
1.用来实现上一页下一页，我直接写到查询页面上 <%--page的分页--%> <style type="text/css"> a { color: #555555; text-decoration: none; cursor: pointer; } .pages a.p_pre:hover { background-color: #eaeaea; color: #555555; border: 1px solid #cccccc;

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客讲述如何在SpringBoot中整合PageHelper，如何实现带多个条件，以及PageInfo中的属性的中文解释（翻译） 一，jar包 <!-- 分页插件 --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper-spring-boot-starter</artifactId> <version>1.2.3</version> </dependency> 二，注册Configuration插件 package cn.dawn.util; /** * Created by Dawn on 2018/6/24. */ import java.util.Properties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import com.github.pagehelper.PageHelper; /* * 注册MyBatis分页插件PageHelper */ @Configuration public class MybatisConf { @Bean public PageHelper pageHelper() { System.out.println("MyBatisConfiguration.pageHelper()"); PageHelper pageHelper = new PageHelper(); Properties p = new Properties(); p.setProperty("offsetAsPageNum", "true"); p.setProperty("rowBoundsWithCount", "true"); p.setProperty("reasonable", "true"); pageHelper.setProperties(p); return pageHelper; } } 三，dao层接口 package cn.dawn.mapper; import cn.dawn.entity.Sys_noteDetail; import java.util.List; import java.util.Map; /** * Created by Dawn on 2018/4/16. */ public interface INoteDAO { /*笔记分页查询*/ public List<Sys_noteDetail> getOnePagenoteData(Map<String, Object> map) throws Exception; } 做带条件分页最好是Map，因为特别容易整合智能标签，它的多条件就是Map传进来的 四，dao层xml配置 <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="cn.dawn.mapper.INoteDAO"> <!--分页查询--> <select id="getOnePagenoteData" resultType="cn.dawn.entity.Sys_noteDetail"> SELECT * FROM sys_notedetail <where> <if test="dname!= null and dname!=''"> AND dname LIKE '%' #{dname} '%' </if> <if test="startdate!= null and startdate!=''"> AND dentrytime&gt;=#{startdate} </if> <if test="enddate!= null and enddate!=''"> AND dentrytime&lt;=#{enddate} </if> </where> </select> </mapper> 五，调用PageHelper，真正使用它 package cn.dawn.service.impl; import cn.dawn.entity.Sys_noteDetail; import cn.dawn.mapper.INoteDAO; import cn.dawn.service.INoteService; import com.github.pagehelper.PageHelper; import com.github.pagehelper.PageInfo; import org.springframework.stereotype.Service; import org.springframework.transaction.annotation.Transactional; import javax.annotation.Resource; import java.util.Date; import java.util.HashMap; import java.util.List; import java.util.Map; /** * Created by Dawn on 2018/4/16. */ @Service("noteServiceImpl") public class NoteServiceImpl implements INoteService{ @Resource(name = "INoteDAO") private INoteDAO iNoteDAO; public PageInfo<Sys_noteDetail> getOnePagenoteData(Integer pageIndex, Integer pageSize, String dname, Date startdate, Date enddate) throws Exception { /*创建分页工具类*/ PageHelper.startPage(pageIndex, pageSize); Map<String,Object> map=new HashMap<String,Object>(); map.put("dname",dname); map.put("startdate",startdate); map.put("enddate",enddate); List<Sys_noteDetail> docs = iNoteDAO.getOnePagenoteData(map); PageInfo<Sys_noteDetail> pageInfo = new PageInfo<>(docs); return pageInfo; } } 六，讲述一下PageInfo，方便调用 //当前页 private int pageNum; //每页的数量 private int pageSize; //当前页的数量 private int size; //由于startRow和endRow不常用，这里说个具体的用法 //可以在页面中"显示startRow到endRow 共size条数据" //当前页面第一个元素在数据库中的行号 private int startRow; //当前页面最后一个元素在数据库中的行号 private int endRow; //总记录数 private long total; //总页数 private int pages; //结果集 private List<T> list; //第一页 private int firstPage; //前一页 private int prePage; //是否为第一页 private boolean isFirstPage = false; //是否为最后一页 private boolean isLastPage = false; //是否有前一页 private boolean hasPreviousPage = false; //是否有下一页 private boolean hasNextPage = false; //导航页码数 private int navigatePages; //所有导航页号 private int[] navigatepageNums; 作者：晨曦Dawn 如果上方博客有错误，或者疑惑，请指出，感激不尽！！！！！！！！！！！！！！！！

//添加 public int addAir(AirModel model) throws Exception; //修改 public int updateAir(AirModel model) throws Exception; //按条件查询 public List<AirModel> findAirByCondition(Map<String,Object> map) throws Exception; //根据编号查询对象的方法 public AirModel selectOneById(Integer id) throws Exception; } dao层接口 注意：他是一个普通的接口，没有注解是因为我在别处配置了一道，在yml有配置，在启动的那个main方法上面也有一道配置 2.dao层的xml <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" > <mapper namespace="cn.happy.mapper.IAirDAO" > <!--01.查询所有记录--> <select id="findAll" resultType="cn.happy.entity.AirModel"> select * from air_quality_index </select> <insert id="addAir"> insert into air_quality_index(district,monitorTime,pm10,pm25,monitoringStation,createDate) values(#{district},#{monitorTime},#{pm10},#{pm25},#{monitoringStation},now()) </insert> <!--修改--> <update id="updateAir"> update air_quality_index set district=#{district},monitorTime=#{monitorTime},pm10=#{pm10},pm25=#{pm25},monitoringStation=#{monitoringStation},createDate=now() where id=#{id} </update> <!--按条件查询--> <select id="findAirByCondition" resultType="cn.happy.entity.AirModel"> select * from air_quality_index <where> <if test='district!="0"'> district=#{district} </if> </where> </select> <!--查询单项--> <select id="selectOneById" resultType="cn.happy.entity.AirModel"> select * from air_quality_index where id=#{id} </select> </mapper> dao的映射xml 注意：命名空间，别名 还有那个智能标签if test里面的写法 直接传的String类型他会报错，说没有getString的方法，所以用map往里传参数 假如test='address!=0'，他会报错，说不可以转换为数字，故写为test='address!="0"'即可 九，service层： 1.接口： package cn.happy.service; import cn.happy.entity.AirModel; import java.util.List; public interface IAirService { //查询所有 public List<AirModel> findAll() throws Exception; //添加 public int addAir(AirModel model) throws Exception;

return 0; } } @Override public int updateAir(AirModel model) throws Exception { return dao.updateAir(model); } @Override public List<AirModel> findAirByCondition(String district) throws Exception { Map<String,Object> map=new HashMap<String,Object>(); map.put("district",district); return dao.findAirByCondition(map); } @Override public AirModel selectOneById(Integer id) throws Exception { return dao.selectOneById(id); } } AirServiceImpl 注意点：和普通的SSM注解开发没有什么太大的区别，值得注意的是事务的运用，需要在main那边开启一道配置 十，controller层： package cn.happy.controller; import cn.happy.entity.AirModel; import cn.happy.service.IAirService; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import javax.annotation.Resource; import javax.validation.constraints.FutureOrPresent; import java.util.List; @Controller public class FirstController { //植入Service @Resource(name = "airService") private IAirService myAirService; @RequestMapping("/goHome") public String getHome(){ return "main"; } @RequestMapping("/findAll") @ResponseBody public Object findAll() throws Exception { List<AirModel> list = myAirService.findAll(); return list; } @RequestMapping("/goAddPage") public String goAddPage(){ return "addAir"; } //添加数据 @RequestMapping("/addAir") public String addAir(AirModel model, Model modelData) throws Exception { int count = myAirService.addAir(model); if (count>0){ return "redirect:goHome"; }else{ modelData.addAttribute("erroMsg","添加失败"); return "redirect:goHome"; } } @RequestMapping("/goUpdatePage") @ResponseBody public Object goUpdatePage(int id) throws Exception { AirModel air = myAirService.selectOneById(id); return air; } @RequestMapping("/updateAir") public String updateAir(AirModel model) throws Exception { int count = myAirService.updateAir(model); return "redirect:goHome"; } //按条件查询 @RequestMapping("selectByCondition") @ResponseBody public Object selectByCondition(String district) throws Exception { List<AirModel> list = myAirService.findAirByCondition(district); return list; } } FirstController 普普通通，做过SSM的发现，没什么不同 十一，SpringBoot核心启动类的配置 package cn.happy; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.transaction.annotation.EnableTransactionManagement; @SpringBootApplication //扫描mapper映射 @MapperScan("cn.happy.*") /*开启事务*/ @EnableTransactionManagement public class ExamApplication { public static void main(String[] args) { SpringApplication.run(ExamApplication.class, args); } } 注意点：开启事务和mybatis的扫描 十二，可以启动项目和调试了 注意： 我没仔细讲js，css，logback，logback就普通配置，无关紧要，css，js放在static下面即可，引入方式可以参考案例，我引用了一个bootstrap的js，这无关紧要，不影响，只需要jquery即可 作者：晨曦Dawn 转载请注明出处，地址：https://www.cnblogs.com/DawnCHENXI/p/9221212.html github地址：（一会上传完成之后，发出来） 如果上方博客有错误或者疑惑，请指出，感激不敬！！！！！！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 上篇博客讲了，如何创建SpringBoot工程，所以，我本篇博客讲述，如何跑起来自己的第一个案例 1.准备一个类，让他成为控制器，Controller，springboot的web项目默认就有与springmvc集成，所以，往下看 package cn.controller; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.ResponseBody; import org.springframework.web.bind.annotation.RestController; /** * Created by Dawn on 2018/6/24. */ @RestController /*@RestController有点像@ResponseBody+@Controller，他这个控制器下的所有，都是返回json串*/ public class FirstController { @RequestMapping("/sayHello") public String sayHello(){ return "sayHi"; } } 2.运行项目创建就有的那个类的main方法，他就可以启动springboot自己默认集成的tomcat服务器 3.如果成功之后，就可以正常访问，通过类似http://localhost:8080/你刚才的requestmappring的路径 8080是tomcat默认端口号，如果要改的话，只需要在application.properties中加一行即可 #tomcat server.port=19090
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 创建SpringBoot工程有很多种方式，我只讲俩种最为常见的 一，依托springboot官网提供的模板。（好处：简单，最新版本） 二，从一个Maven项目中拓展成springboot。（好处：可以控制版本，离线创建） 开始案例 一，通过官网骨架 1.开始创建 2.Next 3.Next 4.Next 5.finish 项目骨架如下 二，通过maven 在第一次通过官网创建过后，我们的maven库里已经有了一个版本的springboot，没有必要每次都下最新版本的，所以，我们可以通过maven仓库创建离线版本 1.正常的maven webapp项目的创建 2.在pom文件中将springboot的节点粘过来 <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>cn.dawn</groupId> <artifactId>z01springbootmyself</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>Z01SpringBootMyself</name> <description>Demo project for Spring Boot</description> <!--springboot的核心--> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.0.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <!--jdk和编码--> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <!--web工程需要的--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--单测需要的--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <build> <!--maven的插件--> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build> </project> 3.按照springboot的骨架创建java，resourse等，上面那张图所示
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 所谓热部署，就是在项目启动中，修改class类中做的修改操作，无需重新启动项目，就可以变更，在网页展示中有直接变更 首先idea需要三步骤： 热部署对于idea比较特殊，jar包+properties/yml的配置还不够，还需要改idea的设置 一，jar包依赖： <!--热部署--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-devtools</artifactId> </dependency> 版本号，作用域那些都不需要管 二，setting配置1： 三，idea设置2： 首先Shift+Ctrl+A快捷键，输入Registry 进入之后，将下图展示的勾挂上 之后重新启动项目，就可以实现热部署 如果上述操作有错误，或者有疑问，可以联系我，帮到朋友是我的荣幸

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- SpringBoot： Spring Boot可以轻松创建独立的，生产级的基于Spring的应用程序，您可以“运行”。 SpringBoot对Spring平台和第三方库有自己的看法（就是有特有的操作），所以您可以不用大惊小怪。大多数Spring Boot应用程序只需要很少的Spring配置。 SpringBoot优点：（特征） 创建独立的Spring应用程序直接嵌入Tomcat，Jetty或Undertow（无需部署WAR文件）提供斟酌的'starter'依赖关系来简化您的构建配置尽可能自动配置Spring和第三方库提供生产就绪功能，如指标，运行状况检查和外部配置绝对不会生成代码，并且不需要XML配置 以上是从官网翻译来的，我可以谈论一下自己理解，以及对springboot的展望 springboot是极其优秀的框架，他可以解决jar包冲突，可以简化配置，而且极易上手，提供的插件很丰富，很强大，也很出色 springboot从2014年开始，带来的影响力是颠覆性的，我觉得，这个框架只会越来越强，越来越主流
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客会详细讲述Spring中的事务，会展开来用语言解释，用于了解概念和准备面试 事务的概念： 一个或者一组sql语句来完成一个功能！要么都执行，要么都不执行 事务具有的四个特性： ACID特性！ 01.原子性：一个事物都是一个不可分割的单位！所有的操作 要么都执行，要么都不执行！ 02.一致性：事务必须是数据库从一个一致性的状态到达另一个一致性的状态！ 03.隔离性：一个事务的执行不会被其他的事务干扰！事务之间相互独立！ 04.持久性：事务一旦被提交！这个操作对数据库来说是永久性的！ Spring的事务管理： 事务本事是数据库中的概念！ 按理说应该在数据访问层（dao）！ 绝大多数的情况下，我们是把事务 提升到 业务逻辑层！ 01.使用spring的事务代理工厂 来 管理事务！ 02.使用spring的注解 来 管理事务！ 常用 03.使用AspectJ的AOP配置 来 管理事务！ 常用 需要掌握的两个属性名： isolation：事务的隔离级别！ 01.default：采用数据库默认的事务隔离级别 001.mysql ---》repeatable-read 002.oracle---》read_committed 02. repeatable-read:可重复读取！解决了脏读，不可重复读，没解决幻读！ 03. read_committed：读已提交！ 解决了脏读，没解决不可重复读，幻读！ 04. read_uncommitted：读未提交！什么都没有解决！ 05. serializable：串行化！级别最高！效率最低！不存在并发的问题！ propagation: 事务的传播行为：一共7中方式！ 01.required：是spring默认的事务传播行为！ 指定的方法必须在事务中执行！如果没有事务，则会自动创建一个事务！ 02.supports:有事务就在事务环境下执行，没有事务就直接执行！ 03.mandatory: 指定的方法必须在事务中执行！如果没有事务，则抛出异常！ 04.requires_new:总是新创建一个事务！ 如果当前方法存在事务，则把当前的事务挂起，直到新创建的事务执行完毕后执行！ 05.not_supported:指定的方法不能在事务中执行！如果当前方法存在事务，则把当前的事务挂起！ 06.never:指定的方法不能在事务中执行！如果当前方法存在事务，则抛出异常！ 07.nested:指定的方法必须在事务内执行！ 如果执行的方法没有事务，则会创建一个事务！ 如果执行的方法没有事务，则会嵌套执行！ timeout_default:定义了事务默认的超时时间！ Spring事务管理的接口：PlatformTransactionManager 常用的两个实现类： 01.使用jdbc和MyBatis时 使用DataSourceTrancationManager 02.使用hibernate时 使用HibernateTrancationManager Spring事务回滚的方式： 默认的回滚方式--》发生运行时异常回滚！发送受查异常时提交！ 受查异常肯定需要我们手动的设置回滚方式！ 运行时异常严重！一旦发生，JVM中止执行！ 实现自定义异常类！RuntimeException --> Exception ---> Throwable
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客讲述Hibernate中的二级缓存的配置，作者将使用的是ehcache缓存 一，目录 1.二级缓存的具体配置 1.1 jar包的引用和注意事项 1.2 ehcache.xml的配置 1.3 集成到hibernate.cfg.xml 1.4 需要使用二级缓存的 XXXX.hbm.xml中的配置 2.二级缓存的测试方法 2.1 测试是否配通，二级缓存存在性的证明 2.2 在二级缓存中设置readonly 2.3 设置二级缓存的模式 二，二级缓存的具体配置 1.jar包的引用和注意事项（我合起来了，用的话打开） <!--Hibernate的核心jar--> <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.2.12.Final</version> </dependency> <!--配置需要的ehcahe插件--> <!-- https://mvnrepository.com/artifact/net.sf.ehcache/ehcache --> <dependency> <groupId>net.sf.ehcache</groupId> <artifactId>ehcache</artifactId> <version>2.10.4</version> </dependency> <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-ehcache --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-ehcache</artifactId> <version>5.2.12.Final</version> </dependency> ehcache需要的jar节点 注意事项：注意hibernate的核心jar和hibernate-ehcache的jar版本号尽可能的保持一致，还有如果使用高版本的hibernate的话ehcache版本太低不合适 hibernate的jar包版本在4.0之前和之后有一个本质的区别，就是配置的区别，我会在后面配置到的时候会讲的 2.ehcache.xml的配置 <?xml version="1.0" encoding="UTF-8"?> <ehcache> <!-- 默认的临时文件--> <diskStore path="java.io.tmpdir"/> <!-- maxElementsInMemory：在内存中对象最大保存数量 eternal：是否永久不销毁 timeToIdleSeconds：最大空闲时间 timeToLiveSeconds：最大存活时间 overflowToDisk：内存溢出是否保存到磁盘 memoryStoreEvictionPolicy 缓存清理策略 1 FIFO first in first out ，先进先出 2 LFU Less Frequently Used ，最少被使用的 2 LRU Least Recently Used ，最近最少使用的，缓存的元素有一个时间戳， 当缓存容量满了，而又需要腾出地方来缓存新的元素的时候， 那么现有缓存元素中时间戳离当前时间最远的元素将被清出缓存。 --> <defaultCache maxElementsInMemory="10000" eternal="false" timeToIdleSeconds="120" timeToLiveSeconds="120" overflowToDisk="true" memoryStoreEvictionPolicy="LRU" /> </ehcache> 3.集成到hibernate.cfg.xml <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!--jdbc连接四要素--> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql:///y2167</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password"></property> <!--在控制台上展示sql--> <property name="show_sql">true</property> <!--格式化sql--> <!--<property name="format_sql">true</property>--> <!--====================================================================--> <!--ddl操作生成策咯，每次运行都在原有表上修改，没有的话就创建表--> <!-- <property name="hbm2ddl.auto"></property> key -

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客讲师Hibernate中的Criteria查询！ 一，Criteria简介： 刚接触Hibernate的时候，就有一个概念，全自动的ORM框架，不用写SQL语句，但是实际我们还是有了另一个名词HQL，这难道是来搞笑的吗？ 其实不然，当你接触到Criteria这个名词的时候，你就知道全自动的魅力了 二，Criteria的优缺点： 优点： 全自动，无需sql，hql，它以Java OOP的思想来操作数据库 使用简单，上手快 缺点： 他对sql语句进行了高级的封装，所以性能不高 对于特别复杂的sql，Criteria无能为力，不过hibernate有sql和hql帮他善后 三，具体使用 我将使用Criteria做 13 个案例，方便大家学习和查阅 1.使用Criteria查询全部 @Test /*查询所有的部门信息*/ public void t1CriteriaSelectAll(){ Criteria criteria = session.createCriteria(Dept.class); List<Dept> depts = criteria.list(); for (Dept dept:depts){ System.out.println(dept); } /* Hibernate: select this_.deptId as deptId1_0_0_, this_.name as name2_0_0_, this_.location as location3_0_0_ from Dept this_ Dept{deptId=1, name='xx部', location='1楼'} Dept{deptId=2, name='研发部', location='2楼'} Dept{deptId=3, name='销售部', location='3楼'} * */ } 2.带条件查询（= 等于的操作） @Test /*带条件查询，查name=研发部的部门信息 * ******************************* * criteria.add(Criterion类型) * Criterion 是一个接口 , 规范 * Restrictions 是一个类， 约束，给我们的查询增加各种条件 * Restrictions所有的方法返回值都是Criterion或者是其实现类，方法的修饰符都是static * */ public void t2CriteriaSelectDeptByParamter(){ Criteria criteria = session.createCriteria(Dept.class); /*加条件*/ criteria.add(Restrictions.eq("name","研发部")); Dept dept = (Dept) criteria.uniqueResult(); System.out.println(dept); /* Hibernate: select this_.deptId as deptId1_0_0_, this_.name as name2_0_0_, this_.location as location3_0_0_ from Dept this_ where this_.name=?

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客将讲述Hibernate中的多对多关联关系的操作，准备的篇幅较少，望海涵 一，讲述多对多 多对多的关联关系，比如学生和教师来说，一个学生由多个教师授课，一个教师授课给多个学生，这就是多对多 讲述多对多，首先要有一个表叫做中间表，他来承载关联关系 二，实体类的创建 1.Stu学生类创建: package cn.dawn.day04.entity; /** * Created by Dawn on 2018/6/2. */ import java.io.Serializable; import java.util.Set; /*学生实体类*/ public class Stu implements Serializable{ private Long sid; private String sname; /*教师对象集合*/ private Set<Tea> teas; public Long getSid() { return sid; } public void setSid(Long sid) { this.sid = sid; } public String getSname() { return sname; } public void setSname(String sname) { this.sname = sname; } public Set<Tea> getTeas() { return teas; } public void setTeas(Set<Tea> teas) { this.teas = teas; } } 2.Tea教室类的创建： package cn.dawn.day04.entity; import java.io.Serializable; import java.util.Set; /** * Created by Dawn on 2018/6/2. */ /*教师实体类*/ public class Tea implements Serializable { private Long tid; private String tname; /*学生对象集合*/ private Set<Stu> stus; public Long getTid() { return tid; } public void setTid(Long tid) { this.tid = tid; } public String getTname() { return tname; } public void setTname(String tname) { this.tname = tname; } public Set<Stu> getStus() { return stus; } public void setStus(Set<Stu> stus) { this.stus = stus; } } 三，hbm.xml文件的创建 1.Stu.hbm.xml <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="cn.dawn.day04.entity"> <!--如果上面指定package的话，class的name就不必写全类名--> <!--lazy:是否懒加载（延迟加载） 默认值是true，延迟加载--> <!--<class name="Teacher">--> <!--直接加载--> <class name="Stu" lazy="false"> <!--主键--> <id name="sid" column="sid"> <!--主键生成策咯 assigned程序员自己创建--> <!--identity是mysql里的自增，一会做增加操作不必再给主键赋值--> <!--increment是先查最大的主键列，在下一条给主键加一--> <!--sequence是oracle的主键生成策咯，他一会需要指定序列名字<param name="sequence">序列名</param>--> <generator class="increment"></generator> </id> <property name="sname" column="tname"></property> <!--table指的是中间表，承载关联关系的表--> <set name="teas" table="tea_stu" cascade="save-update" inverse="false"> <key> <!--本类表的id--> <column name="sid"></column> </key> <!--另外与他有多对多关联的实体类--> <many-to-many class="Tea" column="tid"></many-to-many> </set> </class> </hibernate-mapping> 2.Tea.hbm.xml文件的创建： <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="cn.dawn.day04.entity"> <!--如果上面指定package的话，class的name就不必写全类名--> <!--lazy:是否懒加载（延迟加载） 默认值是true，延迟加载--> <!--<class name="Teacher">--> <!--直接加载--> <class name="Tea" lazy="false"> <!--主键--> <id name="tid" column="tid"> <!--主键生成策咯 assigned程序员自己创建--> <!--identity是mysql里的自增，一会做增加操作不必再给主键赋值--> <!--increment是先查最大的主键列，在下一条给主键加一--> <!--sequence是oracle的主键生成策咯，他一会需要指定序列名字<param name="sequence">序列名</param>--> <generator class="increment"></generator> </id> <property name="tname" column="tname"></property> <!--table指的是中间表，承载关联关系的表--> <set name="stus" table="tea_stu" cascade="save-update" inverse="false"> <key> <!--本类表的id--> <column name="tid"></column> </key> <!--另外与他有多对多关联的实体类--> <many-to-many class="Stu" column="sid"></many-to-many> </set> </class> </hibernate-mapping> 四，hibernate.cfg.xml中管理上方俩个hbm.xml小配置文件 <!--与小配置文件映射--> <mapping resource="cn/dawn/day04/dao/Tea.hbm.xml"></mapping> <mapping resource="cn/dawn/day04/dao/Stu.hbm.xml"></mapping> 五，单测方法： @Test /*同时保存，并建立关联关系*/ public void t1ManyToManyInsert(){ /* * 新建一个教师 */ Tea tea1=new Tea(); tea1.setTname("老雨"); /** * 新建俩个学生 */ Stu stu1=new Stu(); stu1.setSname("小六"); Stu stu2=new Stu(); stu2.setSname("小八"); Set<Stu> students = new HashSet<Stu>(); students.add(stu1); students.add(stu2); /** * 通过课程建立课程与学生之间的关系 */ tea1.setStus(students);//因为课程是一个新的，所以根据没有学生 /*新增*/ session.save(tea1); /*事务提交*/ tr.commit(); /* Hibernate: create table Stu (sid bigint not null, tname varchar(255), primary key (sid)) engine=MyISAM Hibernate: create table Tea (tid bigint not null, tname varchar(255), primary key (tid)) engine=MyISAM Hibernate: create table tea_stu (tid bigint not null, sid bigint not null, primary key (sid, tid)) engine=MyISAM Hibernate: alter table tea_stu add constraint FK1lo22k662lgxr7d79rmfajlu3 foreign key (sid) references Stu (sid) Hibernate: alter table tea_stu add constraint FKgq01y04i2r2ye5pd8abh5x42u foreign key (tid) references Tea (tid) Hibernate: select max(tid) from Tea Hibernate: select max(sid) from Stu Hibernate: insert into Tea (tname, tid) values (?, ?)

Street{id=1, name='海淀1街'} Street{id=2, name='海淀2街'} Street{id=3, name='海淀3街'} * */ } 四，单项多对一：（查询一个指定的街道，并同时展示出其对应的区县） 1.先把二.3.3.1中District.hbm.xml把 <bag节点注释掉，或者直接干掉> <!--<bag name="streets" cascade="save-update" > <key column="districtid"></key> <one-to-many class="Street"></one-to-many> </bag>--> 2.其实应该再多的一方，植入一个少的一方的对象，但是我在准备工作中就已经做过了 /*街道类*/ public class Street { private Integer id;//街道id private String name;//街道名称 /*重点：：：：：：：：：*/ private District district; 3.在Street.hbm.xml配置文件中，把我注释掉的那个<many-to-one>的节点放开： <!--配置多对一的关联关系 name: 本类中 关联关系的属性名 class：关联关系的类型 column：在数据库中两个表的外键 --> <many-to-one name="district" class="District" column="districtId"/> 4.书写测试方法：查询一个指定的街道，并同时展示出其对应的区县： @Test /*查询指定街道所对应的县区*/ /*多对一*/ /*先把之前配置的那个干掉*/ public void t3ManyToOne(){ /*需要在多的一方的实体类加入少的一方对象，并且在hbm配置manytoone*/ Street street = session.get(Street.class, 1); System.out.println(street); /* Hibernate: alter table Street add constraint FKfch89j84iailpfqs5bpkj2rs0 foreign key (districtId) references District (id) Hibernate: select street0_.id as id1_1_0_, street0_.name as name2_1_0_, street0_.districtId as district3_1_0_ from Street street0_ where street0_.id=? Hibernate: select district0_.id as id1_0_0_, district0_.name as name2_0_0_ from District district0_ where district0_.id=? Street{id=1, name='海淀1街', district=District{id=1, name='测试海淀区', streets=[]}} */ } 五，双向一对多（多对一）：（值得注意：toString()套路不对容易引发错误Error------StackOverflowError） 1.解释： 他们的的关系是相互的，都要参与维护关联关系 2.讲四中注释掉District.hbm.xml中的<bag>标签再放开 <bag name="streets" cascade="save-update" > <key column="districtid"></key> <one-to-many class="Street"></one-to-many> </bag> 3.值得注意的是，需要修改toString()方法，否者他会互相调用，出现堆栈溢出的错误 4.先不改toString()的时候，书写测试方法：（查询一个街道及其对应的区县） @Test /*双向的一对多，就是关系是相互的！！！！！！！！*/ /*将t3干掉的配置再加回去*/ public void t4twoway(){ Street street = session.get(Street.class, 1); System.out.println(street); /*注：toString需要做个手段，否则互相调用的话就死循环，堆栈溢出java.lang.StackOverflowError*/ /* Hibernate: alter table Street add constraint FKfch89j84iailpfqs5bpkj2rs0 foreign key (districtId) references District (id) Hibernate: select street0_.id as id1_1_0_, street0_.name as name2_1_0_, street0_.districtId as district3_1_0_ from Street street0_ where street0_.id=? Hibernate: select district0_.id as id1_0_0_, district0_.name as name2_0_0_ from District district0_ where district0_.id=? Hibernate: select streets0_.districtid as district3_1_0_, streets0_.id as id1_1_0_, streets0_.id as id1_1_1_, streets0_.name as name2_1_1_, streets0_.districtId as district3_1_1_ from Street streets0_ where streets0_.districtid=? java.lang.StackOverflowError ...... * */ } 5.修改任意一toString()方法，使其不再互相无节制的调用： /*区县*/ public class District { private Integer id;//区县id private String name;//区县名称 /*一个区县对应多个街道*/ private List<Street> streets=new ArrayList<Street>(); @Override public String toString() { return "District{" + "id=" + id + ", name='" + name + '\'' + ", streets=" + streets.size() + '}'; } 6.重新执行4中的代码，发现不会再出现错误，成功查询 六，inverse的使用和详解：（指定哪一方来维护关联关系） 1.讲解： （1）.Hibernate中的规则是，多的一方必须维护关联关系，所以，我们只能修改一的一方(one-to-many) （2）.inverse默认值为false，就是与数据库交互，会维护关联关系，如果为了性能的提升，我们可以放弃一的一方与数据库交互，即放弃维护关联关系，将值改为true即可； 2.District.hbm.xml中的配置修改的如下： <!-- 配置一对多的关联管理 name:关联关系属性名 column：数据库中对应的外键 class：关联关系的类型 cascade：对当前对象操作的时候，是否影响关联对象 inverse="true"： 放弃与数据库的交互 --> <bag name="streets" cascade="save-update" inverse="false"> <key column="districtid"></key> <one-to-many class="Street"></one-to-many> </bag> 3.单测方法（先测试一的一方维护关联关系）： @Test public void t5inverse(){ //创建区县 District district=new District(2,"大兴区"); //创建街道 Street street1=new Street(4,"大兴3街道"); Street street2=new Street(5,"大兴4街道"); //把街道放进区县的街道集合中 district.getStreets().add(street1); district.getStreets().add(street2); //新增区县 session.save(district); tr.commit(); /** * 产生了8条sql语句！ 发现 后面两条update 是无用功！！！！ Hibernate: alter table Street add constraint FKfch89j84iailpfqs5bpkj2rs0 foreign key (districtId) references District (id) Hibernate: select street_.id, street_.name as name2_1_, street_.districtId as district3_1_ from Street street_ where street_.id=? Hibernate: select street_.id, street_.name as name2_1_, street_.districtId as district3_1_ from Street street_ where street_.id=? Hibernate: insert into District (name, id) values (?, ?) Hibernate: insert into Street (name, districtId, id) values (?, ?, ?) Hibernate: insert into Street (name, districtId, id) values (?, ?, ?) Hibernate: update Street set districtid=? where id=? Hibernate: update Street set districtid=? where id=? 3条insert是 District产生的！ 为什么会产生两条update？？ Street！ hibernate中 规定： 01.多的一方 many-to-one,必须去维护双方的关系！ 因为many-to-one压根就没有inverse这个属性！ 02.inverse默认为false! 不反转！ 我来维护！ 03.必须在一的一方 设置 inverse="true" 放弃维护的权力！ 维护===》是否与数据库产生交互！ */ } 4.将inverse改为true，放弃维护的权力，再执行刚才的代码，发现： /*修改inverse=true，删除刚才添加的数据，再次执行单测*/ /* Hibernate: alter table Street add constraint FKfch89j84iailpfqs5bpkj2rs0 foreign key (districtId) references District (id) Hibernate: select street_.id, street_.name as name2_1_, street_.districtId as district3_1_ from Street street_ where street_.id=? Hibernate: select street_.id, street_.name as name2_1_, street_.districtId as district3_1_ from Street street_ where street_.id=? Hibernate: insert into District (name, id) values (?, ?) Hibernate: insert into Street (name, districtId, id) values (?, ?, ?) Hibernate: insert into Street (name, districtId, id) values (?, ?, ?) 发现后面的update没有了 */ 七，级联删除（慎用慎用慎用！！！！！！！！！！！！！！！！！！！！！！！） 1.讲述： 如果设置完毕后，当干掉主键所在的那张表中的一台记录，它所关联的外键的那一行记录也会被干掉，所以说很危险，不要使用！！ 2.设置District.hbm.xml中的cascade="delete"和inverse="false"（或者inverse不配置） <bag name="streets" cascade="delete" inverse="false"> <key column="districtid"></key> <one-to-many class="Street"></one-to-many> </bag> 3.书写测试代码，比如删一个区县： @Test /*级联删除*/ /*cascade="delete" inverse="false"*/ public void t6deleteMapping(){ /*cascade="delete" inverse="false"记得改这个参数*/ /*获取id为2的区县*/ District district=session.get(District.class,2); /*删除*/ session.delete(district); tr.commit(); /* Hibernate: alter table Street add constraint FKfch89j84iailpfqs5bpkj2rs0 foreign key (districtId) references District (id) Hibernate: select district0_.id as id1_0_0_, district0_.name as name2_0_0_ from District district0_ where district0_.id=? Hibernate: select streets0_.districtid as district3_1_0_, streets0_.id as id1_1_0_, streets0_.id as id1_1_1_, streets0_.name as name2_1_1_, streets0_.districtId as district3_1_1_ from Street streets0_ where streets0_.districtid=? Hibernate: update Street set districtid=null where districtid=? Hibernate: delete from Street where id=? Hibernate: delete from Street where id=? Hibernate: delete from District where id=? * */ /*他会把俩张表的都干掉了，所以，慎用！！！！！！！！！！！！！*/ } 作者：晨曦Dawn 转载请注明出处：https://www.cnblogs.com/DawnCHENXI/p/9123184.html 如果有错误请您指出，感激不尽！！！！！！！！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客讲述Hibernate中的分页 hibernate中的分页其实很好写，它通过操作对象的方式，来进行分页查询操作 分页无非就是查俩个：1.总记录数，2.当前页的数据 根据当前页的页码（第几页）和页大小（每页展示几条数据），写出类似mysql的limit语句的前后值 直接放代码，我会把注释标明： @Test /** * 分页 * * 01.查询总记录数 * 02.每页显示的数据 * 03.总页数 */ public void t1Page(){ String hql="select count(*) from Teacher";//会返回Long类型 int counts=((Long)session.createQuery(hql).uniqueResult()).intValue(); /*页大小*/ int pageSize=2; /*总页数*/ int totalPages=(counts%pageSize==0)?(counts/pageSize):(counts/pageSize+1); /*显示第二页内容*/ int pageIndex=2; hql="from Teacher"; Query query = session.createQuery(hql);; /*从哪一条开始查*/ query.setFirstResult((pageIndex-1)*pageSize); /*设置页大小*/ query.setMaxResults(pageSize); List<Teacher> teachers = query.list(); for (Teacher t:teachers) { System.out.println(t); } }
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客将讲述，以优雅的方式创建session对象，我将会说明优点，并提炼成工具类 优点： 1.无需手动关闭session 2.提高了性能，不需要频繁的创建session对象 说明： 虽然getCurrentSession()底层调用了openSession(),但是做了单例操作，所以性能更高，更安全 工具类： package cn.dawn.util; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.cfg.Configuration; /** * Created by Dawn on 2018/5/30. */ public class SessionFactoryUtil { private static Configuration configuration;//加载核心配置文件 private static SessionFactory factory;//单例对象 //在类加载的时候，加载静态代码块 static { configuration=new Configuration().configure();//默认加载根目录下的hibernate.cfg.xml factory=configuration.buildSessionFactory(); } //通过sessionfactory创建session /*设置同步，保证线程安全*/ public static synchronized Session getCurrentSession(){ return factory.getCurrentSession(); /*不能直接使用，需要在核心配置文件中加入一个节点*/ /*<property name="current_session_context_class">thread</property>*/ } } 另外需要在hibernate.hbm.xml中配置一个节点： <property name="current_session_context_class">thread</property> 简单的使用案例： package cn.dawn.day03; import cn.dawn.day03.entity.Teacher; import cn.dawn.util.SessionFactoryUtil; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import org.hibernate.query.Query; import org.junit.After; import org.junit.Before; import org.junit.Test; import java.util.List; /** * Created by Dawn on 2018/5/25. */ /*分页*/ public class Test0120180530Page { /*事物*/ Transaction tr=null; /*session*/ Session session=null; @Test /** * 分页 * * 01.查询总记录数 * 02.每页显示的数据 * 03.总页数 */ public void t1Page(){ String hql="select count(*) from Teacher";//会返回Long类型 int counts=((Long)session.createQuery(hql).uniqueResult()).intValue(); /*页大小*/ int pageSize=2; /*总页数*/ int totalPages=(counts%pageSize==0)?(counts/pageSize):(counts/pageSize+1); /*显示第二页内容*/ int pageIndex=2; hql="from Teacher"; Query query = session.createQuery(hql);; /*从哪一条开始查*/ query.setFirstResult((pageIndex-1)*pageSize); /*设置页大小*/ query.setMaxResults(pageSize); List<Teacher> teachers = query.list(); for (Teacher t:teachers) { System.out.println(t); } } /*在执行之前加载配置，运行事物*/ @Before public void beforeTest(){ /*使用工具类*/ /*创建session*/ session = SessionFactoryUtil.getCurrentSession(); /*创建事物*/ tr = session.beginTransaction(); } /*在执行之后，提交事物，关闭session*/ @After public void afterTest(){ /*提交事物*/ /*tr.commit();*/ /*关闭session*/ /*session.close();*/ } }
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客将叙述hibernate中的投影查询 一，目录： 1.解释什么是投影查询 2.返回Object单个对象（可以是强类型，无所谓） 3.返回Object数组 4.返回自定义的对象 二，解释什么是投影查询： sql语句： select name,age from userinfo; 如果用hibernate中就不是这么表示，select后面的列名就是需要投影的列，通过特定的写法，直接返回可以操作的对象 三，返回Object单个对象（可以是强类型，无所谓） @Test /*投影成object类型*/ public void t01TouyingObject(){ String hql="select name from Teacher"; List<Object> list = session.createQuery(hql).list(); for (Object t:list){ System.out.println(t); } } 四，返回Object数组 @Test /*投影成object[]类型*/ public void t02TouyingObjectArr(){ String hql="select name,sal from Teacher"; List<Object[]> list = session.createQuery(hql).list(); for (Object[] t:list){ System.out.println(t[0]); System.out.println(t[1]); } } 五，返回自定义的对象 值得注意的是，必须有对应的构造方法： @Test /*投影成自定义对象类型*/ public void t03TouyingObjectMyself(){ String hql="select new Teacher(name,sal) from Teacher"; List<Teacher> list = session.createQuery(hql).list(); for (Teacher t:list){ System.out.println(t); } }

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客主要叙述Hibernate中的三种状态：临时状态（瞬时状态），持久状态，游离状态 commit和flush三种状态间的使用，commit和flush的区别： saveOrUpdate和merge三种状态间的使用，saveOrUpdate和merge的区别 前方标注一下，用的是mysql数据库，主键生成策略是increment 一，Hibernate-ORM的对象的三种状态： * Hibernate对象的三种状态 * 1.临时状态（瞬时态）（临时态，自由态） * 我们通过new关键字创建出一个类的实例对象， 这个对象和hibernate没有任何关系！ * 2.持久状态 * 对象被session管理。就会产生有一个OID（主键标识符）！这个对象和hibernate有关系 * 3.游离状态（托管态） * 曾经被session管理过！有OID *和瞬时态的区别在于，是否存在OID! 大话一下：临时状态就是没有关系，就像你和大街上任意一个女孩没有关系，持久状态就是你和她有了联系（男女朋友，结婚），游离状态就是已经分手了（但是有过曾经） 二，一张图揭秘如何进入各个状态的方法： 三，各个状态的小案例： @Test /*简单写一下三种状态，和根据这个increment主键生成策咯生成记录 * * ---------------------------------- Hibernate: select max(tid) from Teacher ---------------------------------- Hibernate: insert into Teacher (name, tid) values (?, ?) * */ public void t01ThreeStatus01(){ System.out.println("----------------------------------"); Teacher teacher=new Teacher("孟六爱自由");//临时状态（瞬时状态） session.save(teacher);//持久状态 System.out.println("----------------------------------"); tr.commit(); session.evict(teacher);//游离状态 } 四，commit()和flush(): 1.区别： * commit（）和flush()的区别 * * flush()：是缓存清理，把缓存中的数据同步到数据库！但是不会持久化 * commit():在执行的时候，会默认执行flush（），之后会持久化 * flush()在执行的时候会进行缓存清理，在缓存清理的时候，会进行脏检查！ 2. 什么是脏检查？ * 在一个对象被session管理的时候，会创建这个对象的快照， * 我们之后commit的时候，会拿当前的对象信息和之前对象的快照进行对比， * 如果当前对象的属性发生改变，那么现在的对象就是脏对象！ * 脏对象会被同步到数据库中！ 3.对一个持久化状态的commit操作： @Test /* * 写一下commit可以提交属于持久化状态的数据 * Hibernate: select teacher0_.tid as tid1_0_0_, teacher0_.name as name2_0_0_ from Teacher teacher0_ where teacher0_.tid=? Hibernate: update Teacher set name=? where tid=? * */ public void t02CommitAndFlush01(){ Teacher teacher=session.get(Teacher.class,3);/*持久化状态*/ teacher.setName("CommitTest1"); tr.commit(); } 它会在没有update()的情况下也会做修改，并且持久化到数据库 4.对一个持久化状态的flush操作： @Test /* * 写一下flush可以同步到数据库，但是不会持久化 * Hibernate: select teacher0_.tid as tid1_0_0_, teacher0_.name as name2_0_0_ from Teacher teacher0_ where teacher0_.tid=? * * */ public void t02CommitAndFlush02(){ Teacher teacher=session.get(Teacher.class,3);/*持久化状态*/ teacher.setName("flushTest1"); session.flush(); } 它可以同步到数据库，之后执行完毕之后就回滚掉了，不会持久化，我下面一个例子做证明 5.证明flush只是做同步，不是持久化： @Test /* * 测试flush是否真实同步到数据库， * 排除缓存，看看是否确实持久化到数据库中还是只是同步，一会就回滚 * Hibernate: select teacher0_.tid as tid1_0_0_, teacher0_.name as name2_0_0_ from Teacher teacher0_ where teacher0_.tid=? ============================CommitTest1 Hibernate: update Teacher set name=? where tid=? Hibernate: select teacher0_.tid as tid1_0_0_, teacher0_.name as name2_0_0_ from Teacher teacher0_ where teacher0_.tid=? ============================flushTest2 * */ public void t02CommitAndFlush03(){ Teacher teacher=session.get(Teacher.class,3);/*持久化状态*/ System.out.println("============================"+teacher.getName());/*CommitTest1*/ teacher.setName("flushTest2"); session.flush(); //清理缓存 session.clear(); //清空缓存 teacher=session.get(Teacher.class,3);/*持久化状态*/ System.out.println("============================"+teacher.getName());/*flushTest2*/ } 五，saveOrUpdate()和merge(): 1.区别： 最核心的区别：：：：：：：merge()不会改变对象的状态！！！ * save(): 把瞬时态转换成持久态 * update(): 把游离态转换成持久态 * saveOrUpdate(): * 会根据对象是否有OID来判断执行save还是update * 如果有oid 执行update * 如果没有oid 执行save * merge()： 产生的sql语句和saveOrUpdate有点类似， * 但是！！！！！ * 01.merge不会改变对象的状态 * 02.当我们的对象处于瞬时状态时，会将对象复制一份到session的缓存中， * 然后执行save方法，执行insert 2.持久化状态下的saveOrUpdate(): @Test /* * saveOrUpdate * 它会改变状态 * 它会根据有没有oid标识（此java对象的状态），来选择执行save还是update * * 当是update的时候的案例 * Hibernate: select teacher0_.tid as tid1_0_0_, teacher0_.name as name2_0_0_ from Teacher teacher0_ where teacher0_.tid=? Hibernate: update Teacher set name=? where tid=? * */ public void t03SaveOrUpdate01(){ Teacher teacher=session.get(Teacher.class,4);/*持久化状态*/ teacher.setName("SaveOrUpdate01"); session.saveOrUpdate(teacher); /*他走的是update*/ tr.commit(); } 3.临时（瞬时）状态下的SaveOrUpdate(): @Test /* * saveOrUpdate * 它会改变状态 * 它会根据有没有oid标识（此java对象的状态），来选择执行save还是update * * 当是save的时候的案例 * Hibernate: select max(tid) from Teacher Hibernate: insert into Teacher (name, tid) values (?, ?) * * */ public void t03SaveOrUpdate02(){ Teacher teacher=new Teacher("王老师66");//临时状态（瞬时状态） teacher.setName("SaveOrUpdate02"); session.saveOrUpdate(teacher); /*他走的是update*/ tr.commit(); } 4.（临时）瞬时状态下的merge(): @Test /* * Merge和SaveOrUpdate用法类似，但是他不能改变状态，所以有些时候他会有点问题 * 案例一，save * Hibernate: select max(tid) from Teacher Hibernate: insert into Teacher (name, tid) values (?, ?) * */ public void t04Merge01(){ Teacher teacher=new Teacher("Merge01goodnice");//临时状态（瞬时状态） teacher.setName("Merge01"); session.merge(teacher); /*他走的是update*/ tr.commit(); } 5.持久化状态下的merger(): @Test /* * Merge和SaveOrUpdate用法类似，但是他不能改变状态，所以有些时候他会有点问题 * 案例二，update * Hibernate: select teacher0_.tid as tid1_0_0_, teacher0_.name as name2_0_0_ from Teacher teacher0_ where teacher0_.tid=? Hibernate: update Teacher set name=? where tid=? * */ public void t04Merge02(){ Teacher teacher=session.get(Teacher.class,4);/*持久化状态*/ teacher.setName("Merge02"); session.merge(teacher); /*他走的是update*/ tr.commit(); } 6.测试merge()是否会改变对象状态（一）： 先准备一个临时对象，做merge操作，之后做update()操作，因为update得操作持久化对象，所以，只需要看报不报错就知道merge会不会改变状态 @Test /* * Merge和SaveOrUpdate用法类似，但是他不能改变状态，所以有些时候他会有点问题 * 案例三，他不会改变状态的案例 它会抛异常，因为不是持久化状态的无法用update，虽然他已经进行了插入操作 Hibernate: select max(tid) from Teacher Hibernate: insert into Teacher (name, tid) values (?, ?) org.hibernate.TransientObjectException: The given object has a null identifier: cn.dawn.day02.entity.Teacher ........ * */ public void t04Merge03(){ Teacher teacher=new Teacher("Merge03");//临时状态（瞬时状态） session.merge(teacher); /*他走的是save,但是没有改变为持久化状态*/ tr.commit(); session.update(teacher); tr.commit(); } 报错，所以merge()没有改变对象状态 7.测试merge()是否会改变对象状态（二）： 准备一个临时状态的对象，执行俩次merge()，看是发俩条insert还是有update @Test /* * Merge和SaveOrUpdate用法类似，但是他不能改变状态，所以有些时候他会有点问题 * 案例四，创建一个对象后，merge一次，之后改变他的属性，再marge一次。。。 他会执行俩次save，因为此对象是临时状态，merge不会改变java对象的状态 Hibernate: select max(tid) from Teacher Hibernate: insert into Teacher (name, tid) values (?, ?)

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- Hibernate中查多条（全部）使用list()或iterator() 本篇介绍： 1.如何使用list()和iterator()； 2.list()和iterator的相同处与区别； 3.缓存对list()或iterator的影响； 一，list()和iterator()的使用： 1.list(): @Test /*简单的根据list查所有*/ public void t1ListDemo01(){ /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); List<Teacher> list = query.list(); for(Teacher t : list){ System.out.println(t); } } 2.iterator()的使用： @Test /*简单的根据iterate查所有*/ public void t2IterateDemo01(){ /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); Iterator<Teacher> iterate = query.iterate(); while (iterate.hasNext()){ iterate.next(); System.out.println(iterate); } } 二，list()和iterator()的相同不同 1.相同： 查询所使用的hql都一致； 都是可以查多条记录； 都会保存到缓存中； 2.不同： list()他不从缓存中拿值，但是从数据库里查出来的值会保存一道在缓存中； list()它会发送一条sql语句 iterator()发送的sql语句的条数 =（1+记录数） iterator()不从缓存拿值，但是之后的next()如果缓存中有值，是会从缓存中拿值的 next()发送的sql最多只有记录数那么多条sql 三，验证缓存对list()和iterator(）的影响，并且验证二的相同和不同 1.看list()是否从缓存中拿值 @Test /*看list走不走缓存*/ public void t3ListCacheDemo01(){ /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); List<Teacher> list = query.list();/*它在此处都会保存到缓存但是，它查的时候不查缓存*/ for(Teacher t : list){ System.out.println(t); } List<Teacher> list1 = query.list(); for(Teacher t : list1){ System.out.println(t); } } 结论：不会 2.看一下清除缓存是否对list()有影响： @Test /*看list走不走缓存*/ public void t4ListCacheDemo02(){ /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); List<Teacher> list = query.list();/*它在此处都会保存到缓存但是，它查的时候不查缓存*/ for(Teacher t : list){ System.out.println(t); } /*清一下缓存*/ session.clear(); List<Teacher> list1 = query.list(); for(Teacher t : list1){ System.out.println(t); } } 结论：不会有影响 3.测试list()是否会保存数据到缓存中： @Test /*测试list确实会保存到缓存*/ public void t5ListCacheDemo03(){ /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); List<Teacher> list = query.list();/*它在此处都会保存到缓存但是，它查的时候不查缓存*/ for(Teacher t : list){ System.out.println(t); } Teacher teacher = session.get(Teacher.class, 1); } 结论：是的，他查询的时候不从缓存中查询，但是查完数据库会保存数据到缓存中一份 4.测试iterator是否使用缓存，以及他后面的next()是否使用缓存 @Test /*测试iterate是否使用缓存，以及next()是否使用缓存*/ public void t6ListCacheDemo01(){ /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); Iterator<Teacher> iterate = query.iterate(); while (iterate.hasNext()){ iterate.next(); System.out.println(iterate); } Iterator<Teacher> iterate1 = query.iterate(); while (iterate1.hasNext()){ iterate1.next(); System.out.println(iterate); } } @Test /*测试iterate是否使用缓存，以及next()是否使用缓存*/ public void t7ListCacheDemo02(){ Teacher teacher = session.get(Teacher.class, 1); /*创建hql*/ String hql="from Teacher"; Query query = session.createQuery(hql); Iterator<Teacher> iterate = query.iterate(); while (iterate.hasNext()){ iterate.next(); System.out.println(iterate); } } 结论：iterator不从缓存中拿值，但是next()确确实实是用缓存的 作者：晨曦Dawn 转载请注明出处，博客地址：https://www.cnblogs.com/DawnCHENXI/p/9092424.html 如果博客文章有错误，请指出，感激不尽！！！！！！！！！！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客会讲如何用get()或load()查询单个对象和对缓存的简单操作，以及他俩的区别和相同（前面有的那些配置不做重复展示，见谅） Hibernate中查询单个，就是用get()或load()任意一个做操作即可！ 我会讲明区别和相同的地方，再加上一些验证我说的区别和相同的实例： 一，查询单个 1.使用get()查询单个 @Test /*get他是直接加载*/ public void t4GetDemo01(){ System.out.println("----------------------------------"); Teacher teacher = session.get(Teacher.class, 1); System.out.println("----------------------------------"); System.out.println(teacher.getName()); } 2.使用load()查询单个 @Test /*load他是懒加载*/ public void t5LoadDemo01(){ System.out.println("----------------------------------"); Teacher teacher = session.load(Teacher.class, 1); System.out.println("----------------------------------"); System.out.println(teacher.getName()); } 二，相同处： 1.get()和load()都使用缓存，他们查找记录的策咯是，先找一级缓存，有就拿来用，没有再去找二级，二级还没有就找数据库 （验证规则：同样的查俩次，看看发几次sql不就好了么！） /*get查记录从一级缓存开始找，一级没找到去二级找，二级没找到去数据库，数据库没找到返回null*/ @Test /*测试get缓存1*/ /*从他只发一条sql就知道他走的有缓存，因为二级缓存没有配置，所以，是一级缓存*/ public void t6GetCacheDemo01(){ System.out.println("----------------------------------"); Teacher teacher1 = session.get(Teacher.class, 1); Teacher teacher2 = session.get(Teacher.class, 1); System.out.println("----------------------------------"); } 2.他俩使用基本相似，传的同样俩个参数，返回值也一样 三，区别： 1.get()是直接加载，load是懒加载（又称延迟加载） （验证：） /*get和load都是查询，区别：*/ @Test /*get他是直接加载*/ public void t4GetDemo01(){ System.out.println("----------------------------------"); Teacher teacher = session.get(Teacher.class, 1); System.out.println("----------------------------------"); System.out.println(teacher.getName()); } @Test /*load他是懒加载*/ public void t5LoadDemo01(){ System.out.println("----------------------------------"); Teacher teacher = session.load(Teacher.class, 1); System.out.println("----------------------------------"); System.out.println(teacher.getName()); } /*测试在有懒加载的时候不使用它查不查数据*/ public void t12LoadLazyTrueDemo02(){ Teacher teacher = session.load(Teacher.class, 1); System.out.println("----------------------------------"); } 2.查询一个没有的记录，get()返回的是null,load()则会引发异常ObjectNotFoundException @Test /*测试get获取一个没有的值*/ public void t9GetHaventDemo01(){ Teacher teacher = session.get(Teacher.class, 5); System.out.println("----------------------------------"); System.out.println(teacher); } @Test /*测试load获取一个没有的值,会抛ObjectNotFoundException*/ public void t10LoadHaventDemo01(){ Teacher teacher = session.load(Teacher.class, 5); System.out.println("----------------------------------"); System.out.println(teacher); } 四，操作一级缓存查看对get()和load()的影响（清除单个缓存，和全部缓存） @Test /*清除单个缓存*/ public void t7GetCacheDemo02(){ System.out.println("----------------------------------"); Teacher teacher1 = session.get(Teacher.class, 1); Teacher teacher2 = session.get(Teacher.class, 2); System.out.println("----------------------------------"); session.evict(teacher1); teacher1= session.get(Teacher.class, 1); } @Test /*清除全部缓存*/ public void t8GetCacheDemo03(){ System.out.println("----------------------------------"); Teacher teacher1 = session.get(Teacher.class, 1); Teacher teacher2 = session.get(Teacher.class, 2); System.out.println("----------------------------------"); session.clear(); teacher1= session.get(Teacher.class, 1); teacher2 = session.get(Teacher.class, 2); } 结论：get()和load()确实使用到了缓存，如果缓存被清除，他们就得再发sql到数据库去查 五，load()也可以直接加载 方案： 在**.hbm.xml小配置文件中，配置延迟加载lazy=false <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="cn.dawn.day01.entity"> <!--如果上面指定package的话，class的name就不必写全类名--> <!--lazy:是否懒加载（延迟加载） 默认值是true，延迟加载--> <!--<class name="Teacher">--> <!--直接加载--> <class name="Teacher" lazy="false"> <!--主键--> <id name="id" column="tid"> <!--主键生成策咯 assigned程序员自己创建--> <!--identity是mysql里的自增，一会做增加操作不必再给主键赋值--> <!--increment是先查最大的主键列，在下一条给主键加一--> <!--sequence是oracle的主键生成策咯，他一会需要指定序列名字<param name="sequence">序列名</param>--> <generator class="assigned"></generator> </id> <property name="name" column="name"></property> </class> </hibernate-mapping> 测试： @Test /*测试在没有懒加载的时候不使用它查不查数据*/ public void t12LoadLazyTrueDemo02(){ Teacher teacher = session.load(Teacher.class, 1); System.out.println("----------------------------------"); } 作者：晨曦Dawn 转载请注明出处，博客地址：https://www.cnblogs.com/DawnCHENXI/p/9090682.html 如果有错误，请指出，感激不尽！！！！！！！！！！！！！！！！！！！！！！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 此篇博客简单记录五种常用的主键生成策咯： 不同的主键生成策略，生成的sql语句，以及hibernate的操作都是不同的！ 3.1：assigned 主键是由程序猿自己设置的！如果我们不设置，会出现异常！ 3.2：identity 针对于mysql数据库的主键自增 （mysql数据库说了算，必须设置主键自增，否则出现异常） 3.3：sequence 针对于oracle数据库中的序列 <generator class="sequence"> <param name="sequence">序列名称</param> </generator> 3.4：increment 首先会产生一条sql select max(id) from teacher 之后id+1 赋值给主键 3.5：uuid 能够保证在不同的数据库和不同的服务器下，主键的唯一性！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本笔者使用的是Idea+mysql+maven做Hibernate的博客，本篇及其以后都是如此！ 首先写好思路和流水，我说一下会讲什么： 1.pom节点：jar包的引用； 1.1包括如何在不是resource的其他地方编译xml文件 2.核心配置文件hibernate.cfg.xml书写 2.1核心配置文件中的表生成策咯 2.2jdbc的四要素 2.3如何关联小配置文件**.hbm.xml 2.4在控制台展示sql语句与格式化sql语句 3.实体类的创建 4.小配置**.hbm.xml的配置书写 4.1主键生成策咯 4.2实体类和数据表如何映射 5.书写单测增删改 5.1事务环境的运行 话不多少，开始案例： 一，创建maven项目； 1.引入jar包，此处较长，合起来了 <!--单元测试--> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!--Hibernate的核心jar--> <!-- https://mvnrepository.com/artifact/org.hibernate/hibernate-core --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-core</artifactId> <version>5.2.12.Final</version> </dependency> <!--jta 事务的api--> <!-- https://mvnrepository.com/artifact/javax.transaction/jta --> <dependency> <groupId>javax.transaction</groupId> <artifactId>jta</artifactId> <version>1.1</version> </dependency> <!-- 添加Log4J依赖 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.16</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-nop</artifactId> <version>1.6.4</version> </dependency> <!-- 添加javassist --> <dependency> <groupId>javassist</groupId> <artifactId>javassist</artifactId> <version>3.12.0.GA</version> </dependency> <dependency> <groupId>org.hibernate.javax.persistence</groupId> <artifactId>hibernate-jpa-2.0-api</artifactId> <version>1.0.1.Final</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.39</version> </dependency> Hibernate的pom节点 2.使非resource下面的xml参与编译 <build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.xml</include> </includes> </resource> </resources> </build> 二.核心配置文件hibernate.cfg.xml书写 配置了hbm2ddl.auto的话甚至连数据库的表都无需自己创建，只要一个实体类，自动创建数据库的表 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <!--jdbc连接四要素--> <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property> <property name="hibernate.connection.url">jdbc:mysql:///y2167</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.connection.password"></property> <!--在控制台上展示sql--> <property name="show_sql">true</property> <!--格式化sql--> <property name="format_sql">true</property> <!--====================================================================--> <!--ddl操作生成策咯，每次运行都在原有表上修改，没有的话就创建表--> <!-- <property name="hbm2ddl.auto"></property> key - hbm2ddl.auto：自动生成表结构策略 value - update(使用最多)：当数据库不存在表时，hibernate启动后会自动生成表结构。 当数据库表存在时，如果一样，则只会写入数据，不会改变表结构。 当数据库表存在时，如果不一样，则会修改表结构，原有的表结构不会改变。 create（很少）：无论表结构是否存在，hibernate启动后都会重新生成表结构。（造成之前的数据丢失） create-drop（极少）：无论表结构是否存在，hibernate启动都会重新生成表结构。并且hibernate关闭后，表结构会被删除。来无影去无踪。 validate（很少）：不会创建表结构，不会修改表结构。校验与数据库中的表结构是否一样，如果不一样则报异常。 --> <property name="hbm2ddl.auto">update</property> <!--与小配置文件映射--> <mapping resource="cn/dawn/day01/dao/Teacher.hbm.xml"></mapping> </session-factory> </hibernate-configuration> 三，实体类的创建： 此处需要注意的是属性要使用封装类，因为封装类实现了Serializable接口，再举例说明，Interge允许空值，int不行，封装类有更多的功能（方法） 构造也是值得注意的，最好保留一个无参构造，（血泪教训） package cn.dawn.day01.entity; /** * Created by Dawn on 2018/5/25. */ /*实体*/ public class Teacher { private Integer id; private String name; public Integer getId() { return id; } public void setId(Integer id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } @Override public String toString() { return "Teacher{" + "id=" + id + ", name='" + name + '\'' + '}'; } } 四，小配置Teacher.hbm.xml 值得注意的是：1.主键生成策咯，2.导入的包名 <?xml version="1.0"?> <!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> <hibernate-mapping package="cn.dawn.day01.entity"> <!--如果上面指定package的话，class的name就不必写全类名--> <!--lazy:是否懒加载（延迟加载） 默认值是true，延迟加载--> <!--<class name="Teacher">--> <!--直接加载--> <class name="Teacher"> <!--主键--> <id name="id" column="tid"> <!--主键生成策咯 assigned程序员自己创建--> <!--identity是mysql里的自增，一会做增加操作不必再给主键赋值--> <!--increment是先查最大的主键列，在下一条给主键加一--> <!--sequence是oracle的主键生成策咯，他一会需要指定序列名字<param name="sequence">序列名</param>--> <generator class="assigned"></generator> </id> <property name="name" column="name"></property> </class> </hibernate-mapping> 五，书写测试类 1.先写@Before的代码，需要在执行单测前创建事务对象和Session对象 package cn.dawn.day01; import cn.dawn.day01.entity.Teacher; import org.hibernate.Session; import org.hibernate.SessionFactory; import org.hibernate.Transaction; import org.hibernate.cfg.Configuration; import org.junit.After; import org.junit.Before; import org.junit.Test; /** * Created by Dawn on 2018/5/25. */ public class Test0120180525InsertDeleteUpdate { /*事物*/ Transaction tr=null; /*session*/ Session session=null; /*在执行之前加载配置，运行事物*/ @Before public void beforeTest(){ /*加载hibernate核心*/ Configuration cfg=new Configuration().configure(); /*创建session工厂*/ SessionFactory sessionFactory=cfg.buildSessionFactory(); /*创建session*/ session = sessionFactory.openSession(); /*创建事物*/ tr = session.beginTransaction(); } } 2.创建@After的方法，用于单测结束后提交事务和关闭Session对象 /*在执行之后，提交事物，关闭session*/ @After public void afterTest(){ /*提交事物*/ tr.commit(); /*关闭session*/ session.close(); } 3.增：根据不同的主键生成策咯，它的新增写法不同 如果是identity就无需往对象set主键id值 如果是assigned则需要程序员自己创建，必须给set主键值，否者抛异常 /*Demo01最简单的Hibernate例子，做一下添加操作*/ public void t1InsertDemo(){ System.out.println("----------------------------------"); /*创建一个对象*/ Teacher teacher=new Teacher(); teacher.setId(1); teacher.setName("孟六"); /*调用执行*/ session.save(teacher); System.out.println("----------------------------------"); } 4.改：会根据您传进来的主键值改其他属性 @Test /*Demo01最简单的Hibernate例子，做一下添加操作*/ public void t1InsertDemo(){ System.out.println("----------------------------------"); /*创建一个对象*/ Teacher teacher=new Teacher(); teacher.setId(1); teacher.setName("孟六"); /*调用执行*/ session.save(teacher); System.out.println("----------------------------------"); } 5.删除：只需要一个有主键id的对象，就可以删除您表中的对应的记录 @Test /*删除*/ public void t2DeleteDemo(){ System.out.println("----------------------------------"); Teacher teacher=new Teacher(); teacher.setId(1); session.delete(teacher); System.out.println("----------------------------------"); } 作者：晨曦Dawn 转载请注明出处：https://www.cnblogs.com/DawnCHENXI/p/9090482.html 如有错误，请指出，感激不尽！！！！！！！！！！！！！！！！！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 对于学过ORM框架的朋友来说，上手HibernateORM来说，既熟悉有有一点陌生，熟悉无非是灵魂相通，陌生的只是一些语言罢了 1.1：Hibernate-ORM简介 1.Hibernate是一个开发源代码的对象关系映射框架（ORM）; 2.对JDBC进行了轻量级的封装，可以将实体类和数据库中的表产生映射关系; 3.是一个全自动的ORM框架；hibernate能自动生成sql语句; 4.程序猿可以完全按照面向对象的编程思想来操作数据库. Hibernate ORM: 我们研究的主题； Hibernate Search:类似于lucence全文检索 Hibernate Validator:验证框架 Hibernate OGM：针对于Nosql数据库的操作 1.2：核心配置文件hibernate.cfg.xml <?xml version="1.0" encoding="UTF-8"?><!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 配置文件中的需要我们配置的重要内容： 01.连接数据库的四要素 02.管理各种hbm.xml映射文件 03.缓存的设置 04.是否显示sql语句 05.是否格式化sql语句 06.hbm2ddl的配置 1.2：核心API 1. Configuration 类----------------》对应mybatis的SqlsessionFactoryBuilder 加载hibernate的核心配置文件，以及负责启动hibernate，创建SessionFactory对象 2. SessionFactory 接口----------------》对应mybatis的SqlsessionFactory 初始化Hibernate,是数据存储源的代理，负责创建Session对象！ 一个项目中我们使用一个SessionFactory就足够了！ 如果我们需要操作多个数据库时，建立每个数据库指定一个SessionFactory！ 3. Session接口----------------》对应mybatis的Sqlsession 负责执行持久化对象的CRUD操作！是线程不安全的！可以开启事务！创建Transaction对象！ Session ===>会话session HttpSession ===>用户session 4. Transaction接口 针对于事务的操作！ 5. Query接口 方便我们对数据库数据的查询，有两种方式来实现查询： 01.sql 02.hql 6. Criteria接口 和query接口非常相似！完全面向对象的思想去操作数据库！
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 先说明此篇博客看明白了可以干嘛： 就是在js或者jquery中操作一个EL表达式的一个list集合或者复杂类型或者内存地址 首先说明，从el表达式拿到的复杂类型，包括内存地址，js是无法直接进行操作的，所以得转换为简单类型，不是直接拿内存地址操作 eval也操作不了内存地址 我先说明思路：就是先用jstl转换为为简单类型，然后对简单类型做操作，示例不写的复杂，看一下就好： /*最牛的判断方式！！！！！！！*/ var flagchongfu=false; var array = new Array(); <c:forEach items="${muser.sysCourseList}" var="t"> array.push(${t.vid}); //js中可以使用此标签，将EL表达式中的值push到数组中 </c:forEach> for(var i=0;i<array.length;i++) { if(array[i]==id){ flagchongfu=true; } } if(flagchongfu==true){ layer.alert('不要重复购买', {icon: 2}); return; } 作者：晨曦Dawn 作者的博客园地址：http://www.cnblogs.com/DawnCHENXI/p/9061478.html 转载请注明出处！ 参考博客：天降爆米花 https://blog.csdn.net/dream20nn/article/details/51496860
------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 本篇博客记录了表分区 表分区的含义： 典型的拿空间换时间的案例！ 表分区对一张表进行分区，分区之后表中的数据存在相对应的分区内（可以是不同物理存储的位置），实际上他还是一张表！！！！！！！ 表分区的好处： 均衡了IO（可以放在多个不同磁盘的位置） 提升了查询性能（可以不必检索所有记录） 维护方便（假如数据出现问题，分区之后只需维护出现问题的那个分区） 增强了可用性（假如一个表分区挂掉了，其他分区可以继续使用，而不是全挂掉） 表分区的缺点： 假如数据量太小，就无需使用表分区，否者浪费性能 提供数据库脚本供测试使用：（合起来了，以免影响阅读） create table DEPT ( deptno NUMBER(2) not null, dname VARCHAR2(20), loc VARCHAR2(13) );

------------吾亦无他,唯手熟尔，谦卑若愚，好学若饥------------- 拦截器Interceptor: 对处理方法进行双向的拦截，可以对其做日志记录等 我选择的是实现HandlerInterceptor接口 我把执行流程放上来，单个拦截器的和多个拦截器的，然后写个Demo案例，就可以正式结束Springmvc，过几天写完SSM整合，SSM就结束了，将来有机会多放几个项目在博客园上 图1，单个拦截器执行流程 图2，多个拦截器的执行流程 我会给大家定义俩个拦截器，大家跑一下，看看执行顺序，另外大家可以举一反三的扩充，定义多个拦截器或者在拦截器的方法中填实际的处理代码 案例Demo开始 1.自定义第一个拦截器FirstInterceptor package cn.dawn.day25interceptor;/** * Created by dawn on 2018-04-02. */ import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class FirstInterceptor implements HandlerInterceptor{ //在Handler执行前执行 public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception { System.out.println("preHandle============="); return true; } public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception { System.out.println("postHandle============="); } public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception { System.out.println("afterCompletion============="); } } preHandle这个方法，它的返回值决定了下面俩个方法是否执行，如果false，则不会执行下面的那俩方法 2.自定义第二个拦截器SecondInterceptor package cn.dawn.day25interceptor;/** * Created by dawn on 2018-04-02. */ import org.springframework.web.servlet.HandlerInterceptor; import org.springframework.web.servlet.ModelAndView; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; public class SecondInterceptor implements HandlerInterceptor { public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o) throws Exception { System.out.println("Second preHandle============="); return true; } public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) throws Exception { System.out.println("Second postHandle============="); } public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) throws Exception { System.out.println("Second afterCompletion============="); } } 3.自定义处理器和处理方法 package cn.dawn.day25interceptor;/** * Created by dawn on 2018-04-02. */ import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; @Controller public class FirstController { @RequestMapping("/first") public String doFirst(){ System.out.println("Handler method"); return "success"; } } 4.自己的xml配置文件中配置一道，将拦截器配置上去 <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <!--包扫描器--> <context:component-scan base-package="cn.dawn.day25interceptor"></context:component-scan> <!--视图解析器--> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/day25/"></property> <property name="suffix" value=".jsp"></property> </bean> <!--拦截器配置--> <mvc:interceptors> <!--配置多个拦截器，多个拦截器链--> <mvc:interceptor> <mvc:mapping path="/**"/> <bean class="cn.dawn.day25interceptor.FirstInterceptor"></bean> </mvc:interceptor> <mvc:interceptor> <mvc:mapping path="/**"/> <bean class="cn.dawn.day25interceptor.SecondInterceptor"></bean> </mvc:interceptor> </mvc:interceptors> <!--绑定注解驱动--> <mvc:annotation-driven></mvc:annotation-driven> </beans> 此处的拦截器位置的前后，决定了他们执行的先后 此处的/**表示任意多级目录的任意方法，全部的意思 5.修改web.xml的中央调度器的上下文配置位置为上面那个xml 6.jsp页面，我不是return了个success么，所以建一个success.jsp <%-- Created by IntelliJ IDEA.
