为了之后学习的日子里加深对框架的理解和使用，这里将搭建步奏简单写一下，目的主要是方便以后自己回来脑补；
1:File--->New--->Other--->Maven--->Maven Project--->Next（之后界面如下所示：）
--->Next（点击next之后出现如下界面：选择最后一个 maven-archetype-webapp,然后点击next）
--->Next(点击next之后出现如下界面，然后选择好组织号，工程号，版本号即可)，最后点击Finish
2：maven项目创建好之后会报错，这里先在pom.xml中导入jar包，导入方式如下所示：这个pom配置好之后点击保存会将jar包下载到本地仓库，这个学习maven的时候都配置过，这个自己下去脑补吧；

3：web.xml里面的dtd默认是2.3的，不过2.3的不支持el表达式，所以这里修改为2.5的。配置如下所示：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 3 <display-name>Archetype Created Web Application</display-name> 4 5 6 <display-name>Archetype Created Web Application</display-name> 7 8 </web-app>
4：项目配置好上面的，接下来开始写代码，首先从web.xml的配置开始，比如struts2的核心过滤器，spring核心配置文件，监听器；
1 <?xml version="1.0" encoding="UTF-8"?> 2 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> 3 <display-name>Archetype Created Web Application</display-name> 4 5 6 <display-name>Archetype Created Web Application</display-name> 7 8 <!-- 配置spring的监听器 ,加载本地的springp配置文件--> 9 <context-param> 10 <param-name>contextConfigLocation</param-name> 11 <param-value>classpath:bean-*.xml</param-value> 12 </context-param> 13 14 <!-- 15 spring的监听器 spring-web-3.2.4.RELEASE.jar ==》org.springframework 16 ==》context ==》ContextLoaderListener 17 --> 18 <listener> 19 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> 20 </listener> 21 22 23 <!-- 24 struts2的核心过滤器 25 1:filter-class ==》 struts2-core-2.3.8.jar ==》org.apache.struts2 26 ==》 dispatcher ==》 ng ==》filter ==》StrutsPrepareAndExecuteFilter 27 --> 28 <filter> 29 <filter-name>struts2Filter</filter-name> 30 <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class> 31 </filter> 32 <filter-mapping> 33 <filter-name>struts2Filter</filter-name> 34 <url-pattern>/*</url-pattern> 35 </filter-mapping> 36 37 </web-app>
5：配置好之后就需要配置一下maven标准格式：在src/main下面创建一个java的文件夹，在src/下面创建一个test，在test下面创建java文件夹，配置如下所示：
6：简单测试一下，将项目发布到tomcat中，启动tomcat,运行之后tomcat不报错，说明项目正常；
7：将spring的配置文件bean-common.xml配置文件放到src/main/resources下面即可（src/main/resources也是根目录）：配置如下所示：
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:aop="http://www.springframework.org/schema/aop" 7 xmlns:tx="http://www.springframework.org/schema/tx" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans.xsd 10 http://www.springframework.org/schema/context 11 http://www.springframework.org/schema/context/spring-context.xsd 12 http://www.springframework.org/schema/aop 13 http://www.springframework.org/schema/aop/spring-aop.xsd 14 http://www.springframework.org/schema/tx 15 http://www.springframework.org/schema/tx/spring-tx.xsd"> 16 17 18 </beans>
1 <?xml version="1.0" encoding="UTF-8"?> 2 <beans xmlns="http://www.springframework.org/schema/beans" 3 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 4 xmlns:p="http://www.springframework.org/schema/p" 5 xmlns:context="http://www.springframework.org/schema/context" 6 xmlns:aop="http://www.springframework.org/schema/aop" 7 xmlns:tx="http://www.springframework.org/schema/tx" 8 xsi:schemaLocation="http://www.springframework.org/schema/beans 9 http://www.springframework.org/schema/beans/spring-beans.xsd 10 http://www.springframework.org/schema/context 11 http://www.springframework.org/schema/context/spring-context.xsd 12 http://www.springframework.org/schema/aop 13 http://www.springframework.org/schema/aop/spring-aop.xsd 14 http://www.springframework.org/schema/tx 15 http://www.springframework.org/schema/tx/spring-tx.xsd"> 16 17 18 <!-- 1. 连接池实例 --> 19 <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"> 20 <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh"></property> 21 <property name="driverClass" value="com.mysql.jdbc.Driver"></property> 22 <property name="user" value="root"></property> 23 <property name="password" value="123456"></property> 24 <property name="initialPoolSize" value="3"></property> 25 <property name="maxPoolSize" value="6"></property> 26 </bean> 27 28 <!-- 2.

8：将struts的配置文件struts.xml配置文件放到src/main/resources下面即可（src/main/resources也是根目录）：配置如下所示：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 4 "http://struts.apache.org/dtds/struts-2.3.dtd"> 5 6 <struts> 7 8 9 </struts>
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE struts PUBLIC 3 "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN" 4 "http://struts.apache.org/dtds/struts-2.3.dtd"> 5 6 <struts> 7 8 <package name="admin_package" extends="struts-default"> 9 10 <!-- Ation实例交给spring容器创建 --> 11 <action name="select_*" class="adminAction" method="{1}"> 12 13 <!-- 列表展示 --> 14 <result name="success">index.jsp</result> 15 16 </action> 17 </package> 18 19 </struts>
9：配置到第八步，基本结束，开始写代码，创建一个实体类Admin；如下所示：
1 package com.bie.po; 2 3 /** 4 * @author 作者:别先生 5 * @version 创建时间:2017年6月10日 下午2:08:17 6 * 类说明 7 */ 8 9 public class Admin { 10 11 private Integer adminId;//管理员编号 12 private String adminName;//管理员姓名 13 private String adminPwd;//管理员密码 14 15 public Integer getAdminId() { 16 return adminId; 17 } 18 public void setAdminId(Integer adminId) { 19 this.adminId = adminId; 20 } 21 public String getAdminName() { 22 return adminName; 23 } 24 public void setAdminName(String adminName) { 25 this.adminName = adminName; 26 } 27 public String getAdminPwd() { 28 return adminPwd; 29 } 30 public void setAdminPwd(String adminPwd) { 31 this.adminPwd = adminPwd; 32 } 33 @Override 34 public String toString() { 35 return "Admin [adminId=" + adminId + ", adminName=" + adminName + ", adminPwd=" + adminPwd + "]"; 36 } 37 38 39 }
10：创建好实体类之后配置一个hibernate的映射文件；Admin.hbm.xml,代码如下所示：
1 <?xml version="1.0" encoding="UTF-8" ?> 2 <!DOCTYPE hibernate-mapping PUBLIC 3 "-//Hibernate/Hibernate Mapping DTD 3.0//EN" 4 "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"> 5 6 <!-- hibernate的实体类映射文件的配置，package包指出总包所在 --> 7 <hibernate-mapping package="com.bie.po"> 8 9 <!-- class的name是实体类的名字，table是数据表名 --> 10 <class name="Admin" table="admin"> 11 <id name="adminId"> 12 <!-- native设置自增 --> 13 <generator class="native"></generator> 14 </id> 15 16 <!-- 非主键的映射 --> 17 <property name="adminName" length="20"></property> 18 <property name="adminPwd" length="20"></property> 19 </class> 20 21 </hibernate-mapping> 22
11：创建好实体类之后开始创建dao层的接口和实现类，如AdminDao接口和AdminDaoImpl实现类；
1 package com.bie.dao; 2 3 import java.util.List; 4 5 import com.bie.po.Admin; 6 7 /** 8 * @author 作者:别先生 9 * @version 创建时间:2017年6月10日 下午2:25:01 10 * 类说明 11 */ 12 13 public interface AdminDao { 14 15 /** 16 * 查询管理员的信息 17 * @param admin 18 * @return 19 */ 20 public List<Admin> selectAdmin(); 21 }
1 package com.bie.dao.impl; 2 3 import java.util.List; 4 5 import org.hibernate.SessionFactory; 6 7 import com.bie.dao.AdminDao; 8 import com.bie.po.Admin; 9 10 /** 11 * @author 作者:别先生 12 * @version 创建时间:2017年6月10日 下午2:25:15 13 * 类说明 14 */ 15 16 public class AdminDaoImpl implements AdminDao{ 17 18 //IOC容器注入sessionFactory对象 19 private SessionFactory sessionFactory; 20 public void setSessionFactory(SessionFactory sessionFactory) { 21 this.sessionFactory = sessionFactory; 22 } 23 24 public List<Admin> selectAdmin() { 25 26 List<Admin> list = sessionFactory.getCurrentSession().createQuery(" from Admin ").list(); 27 28 return list; 29 } 30 31 32 }
12：创建好dao层接口和实现类之后开始创建service层的接口和实现类，如AdminService接口和AdminServiceImpl实现类；
1 package com.bie.service; 2 3 import java.util.List; 4 5 import com.bie.po.Admin; 6 7 /** 8 * @author 作者:别先生 9 * @version 创建时间:2017年6月10日 下午2:29:20 10 * 类说明 11 */ 12 13 public interface AdminService { 14 15 public List<Admin> selectAdmin(); 16 }
1 package com.bie.service.impl; 2 3 import java.util.List; 4 5 import com.bie.dao.AdminDao; 6 import com.bie.po.Admin; 7 import com.bie.service.AdminService; 8 9 /** 10 * @author 作者:别先生 11 * @version 创建时间:2017年6月10日 下午2:29:40 12 * 类说明 13 */ 14 15 public class AdminServiceImpl implements AdminService{ 16 17 //ioc容器注入 18 private AdminDao adminDao; 19 public void setAdminDao(AdminDao adminDao) { 20 this.adminDao = adminDao; 21 } 22 23 public List<Admin> selectAdmin(){ 24 25 List<Admin> list = adminDao.selectAdmin(); 26 27 return list; 28 } 29 }
13:当写好service层之后开始写action层AdminAction，这里传递前台页面的参数；代码如下所示：
1 package com.bie.action; 2 3 import java.util.List; 4 import java.util.Map; 5 6 import org.apache.struts2.interceptor.RequestAware; 7 8 import com.bie.po.Admin; 9 import com.bie.service.AdminService; 10 import com.opensymphony.xwork2.ActionSupport; 11 12 /** 13 * @author 作者:别先生 14 * @version 创建时间:2017年6月10日 下午2:36:07 15 * 类说明 16 */ 17 18 public class AdminAction extends ActionSupport implements RequestAware{ 19 20 21 private static final long serialVersionUID = 1L; 22 23 //ioc容器注入 24 private AdminService adminService; 25 public void setAdminService(AdminService adminService) { 26 this.adminService = adminService; 27 } 28 29 // 接收框架运行时候传入的代表request对象的map 30 private Map<String, Object> request; 31 public void setRequest(Map<String, Object> request) { 32 this.request = request; 33 } 34 35 36 //ioc容器注入 37 private Admin admin; 38 public void setAdmin(Admin admin) { 39 this.admin = admin; 40 } 41 public Admin getAdmin() { 42 return admin; 43 } 44 45 public String selectAdmin(){ 46 47 List<Admin> list = adminService.selectAdmin(); 48 49 //将信息保存到request中 50 request.put("list", list); 51 52 return "success"; 53 } 54 55 56 }
14:当后台写完之后开始写前台测试页面：页面如下所示
1 <%@ page language="java" contentType="text/html; charset=UTF-8" 2 pageEncoding="UTF-8"%> 3 <%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%> 4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> 5 <html> 6 <head> 7 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> 8 <title>主页显示管理员的信息</title> 9 </head> 10 <body> 11 12 <a href="select_selectAdmin.action">查询所有用户信息</a> 13 14 <center> 15 <table cellspacing="20" cellpadding="20"> 16 <tr> 17 <th>管理员编号</th> 18 <th>管理员姓名</th> 19 <th>管理员密码</th> 20 </tr> 21 <c:forEach items="${list }" var="list"> 22 <tr> 23 <td>${list.adminId}</td> 24 <td>${list.adminName}</td> 25 <td>${list.adminPwd }</td> 26 </tr> 27 </c:forEach> 28 </table> 29 </center> 30 31 </body> 32 </html>
直接访问index.jsp页面，测试结果如下所示：
ssh配置版框架搭建先到这吧，以后有机会再深学吧。时间过的挺快的，马上就该出去找工作了......
增删改查功能日后有时间再写吧......
