什么是spring boot
Spring Boot是由Pivotal团队提供的全新框架,其设计目的是用来简化新Spring应用的初始搭建以及开发过程。该框架使用了特定的方式来进行配置,从而使开发人员不再需要定义样板化的配置。
为什么要使用spring boot
Spring IO大量的XML配置以及复杂的依赖管理一直是其饱受非议的一点。而Boot的实现不仅仅实现了免XML配置的开发体验,而且在一些场景中甚至不需要编写繁琐的import语句。Spring Boot的目标不在于为已解决的问题域提供新的解决方案,而是为平台带来另一种开发体验,从而简化对这些已有技术的使用。对于已经熟悉Spring生态系统的开发人员来说,Boot是一个很理想的选择,不过对于采用Spring技术的新人来说,Boot提供一种更简洁的方式来使用这些技术。
使用Spring Boot
要进行打包和分发的工程会依赖于像
Maven或
Gradle这样的构建系统。为了简化依赖图,Boot的功能是模块化的,通过导入Boot所谓的“starter”模块,可以将许多的依赖添加到工程之中。官方网站给我们提供了集成相关服务的项目例子,我们直接下载
https://start.spring.io/。
为了更容易地管理依赖版本和使用默认配置,框架提供了一个parent POM,工程可以继承它。Spring Boot工程的样例POM文件定义如下所示:

构建Boot web应用
1.在配置文件中引入Spring Boot的web依赖:
- <dependency>
- <groupId>org.springframework.boot</groupId>
- <artifactId>spring-boot-starter-web</artifactId>
- </dependency>
2.开始编写代码,由于Maven默认编译路径为 src/main/java 下面的源码,所以,默认设置下,需要创建一些文件夹。
编写文件src\main\java\com\example\hello\HelloController.java:
- package com.example.hello;
- import org.springframework.web.bind.annotation.RequestMapping;
- import org.springframework.web.bind.annotation.RequestParam;
- import org.springframework.web.bind.annotation.RestController;
- import java.util.Map;
- import java.util.ArrayList;
- import java.util.HashMap;
- import java.util.List;
- /**
- * Created by wuhaochao on 2017/7/12.
- */
- @RestController
- @RequestMapping("/hello")
- public class HelloController {
- @RequestMapping("/index")
- public String index(@RequestParam String name) {
- // return "hello word" + name;
- return "index";
- }
- @RequestMapping("/info")
- public Map<String, String> getInfo(@RequestParam String name) {
- Map<String, String> map = new HashMap<>();
- map.put("name", name);
- return map;
- }
- @RequestMapping("/list")
- public List<Map<String, String>> getList() {
- List<Map<String, String>> list = new ArrayList<>();
- Map<String, String> map = null;
- for (int i = 1; i <= 5; i++) {
- map = new HashMap<>();
- map.put("name", "Shanhy-" + i);
- list.add(map);
- }
- return list;
- }
- }
@RestController因为我们例子是写一个web应用,因此写的这个注解,这个注解相当于同时添加@Controller
和@ResponseBody
注解。
创建一个Application
类:
- package com.example;
- import org.apache.cxf.transport.servlet.CXFServlet;
- import org.springframework.boot.SpringApplication;
- import org.springframework.boot.autoconfigure.SpringBootApplication;
- import org.springframework.boot.builder.SpringApplicationBuilder;
- import org.springframework.boot.web.servlet.ServletComponentScan;
- import org.springframework.boot.web.servlet.ServletRegistrationBean;
- import org.springframework.boot.web.support.SpringBootServletInitializer;
- import org.springframework.context.annotation.Bean;
- import org.springframework.scheduling.annotation.EnableAsync;
- import org.springframework.scheduling.annotation.EnableScheduling;
- import org.springframework.transaction.PlatformTransactionManager;
- import org.springframework.transaction.annotation.EnableTransactionManagement;
- import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
- import org.springframework.web.servlet.DispatcherServlet;
- //@EnableScheduling//启动定时探测
- @EnableAsync//启动自定义线程池
- @EnableTransactionManagement//启动事物管理
- @SpringBootApplication
- public class DemoApplication extends SpringBootServletInitializer {
- @Override
- protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
- return application.sources(DemoApplication.class);
- }
- @Bean
- public ServletRegistrationBean restServlet() {
- //注解扫描上下文
- AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
- // base package 这里指定到controller不指定*,因为配置有定时任务,容易造成bean冲突,导致定时任务执行2次
- applicationContext.scan("com.example.controller");
- // /通过构造函数指定dispatcherServlet的上下文
- DispatcherServlet rest_dispatcherServlet = new DispatcherServlet(applicationContext);
- // 用ServletRegistrationBean包装servlet
- ServletRegistrationBean registrationBean = new ServletRegistrationBean(rest_dispatcherServlet);
- registrationBean.setLoadOnStartup(1);
- //指定urlmapping
- registrationBean.addUrlMappings("/webapp/*");
- // 指定name,如果不指定默认为dispatcherServlet
- registrationBean.setName("webapp");
- return registrationBean;
- }
- @Bean
- public Object testBean(PlatformTransactionManager platformTransactionManager) {
- System.out.println(">>>>>>>>>>>>>>>>>" + platformTransactionManager.getClass().getName() + "<<<<<<<<<<<<<<<<<<<<<");
- return new Object();
- }
- public static void main(String[] args) {
- SpringApplication.run(DemoApplication.class, args);
- }
- }<strong>
- </strong>
注意Spring Boot建议将我们main
方法所在的这个主要的配置类配置在根包src名下。
继承SpringBootServletIntializer和方法configure是后期为实现跳转前端页面的配置。
启动项目就可以在浏览器访问了。
数据访问
在配置文件application.properties中配置数据源:
- #数据源设置
- spring.datasource.url=jdbc:mysql://localhost:3306/stu_info
- spring.datasource.username=root
- spring.datasource.password=111111
- spring.datasource.driver-class-name=com.mysql.jdbc.Driver
- spring.datasource.max-idle=10
- #指定连接池等待连接返回的最大等待时间,毫秒单位.
- spring.datasource.max-wait=10000
- #指定必须保持连接的最小值
- spring.datasource.min-idle=5
- #指定连接池中最大的活跃连接数.
- spring.datasource.secondary.max-active=50
- spring.datasource.initial-size=5
- spring.datasource.validation-query=SELECT 1
- spring.datasource.test-on-borrow=false
- spring.datasource.test-while-idle=true
- spring.datasource.time-between-eviction-runs-millis=18800
- spring.datasource.jdbc-interceptors=ConnectionState;SlowQueryReport(threshold=0)
- #mybatis数据文件路径
- mybatis.mapper-locations=com/example/mapper/sql/*Mapper.xml
- mybatis.type-aliases-package=com.example.entity
添加mybatis相关依赖:

- List<TranscationBean> list = transcationMapper.getTranscation();
- return new PageInfo(list);
- }
- }
Spring Boot定时任务相对Spring quartz来说更简单。
定义一个定时任务:
- package com.example.Scheduled;
- /**
- * Created by wuhaochao on 2017/7/21.
- */
- import com.example.mapper.BlockMapper;
- import com.example.mapper.TranscationMapper;
- import com.example.theadPoolConfig.AsyncTranscationTask;
- import com.example.unitl.Until;
- import org.slf4j.Logger;
- import org.slf4j.LoggerFactory;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.scheduling.annotation.Scheduled;
- import org.springframework.stereotype.Component;
- import org.springframework.transaction.annotation.Transactional;
- /**
- * 定时任务,每五秒探测一次区块链中的是否存在最新交易信息
- */
- @Component
- public class MyScheduled {
- private static final Logger logger = LoggerFactory.getLogger(MyScheduled.class);
- @Autowired
- private AsyncTranscationTask asyncTranscationTask;
- @Autowired
- private BlockMapper blockMapper;
- /*每天每5秒执行一次*/
- @Scheduled(cron = "0/5 * * * * ?")
- @Transactional
- public void executeTask2() {
- // 获取最新区块编号
- try {
- int blockNumberNew = Integer.parseInt(
- Until.encodeHexTodecimal(Until.JSONRPCClient(new Object[]{},
- "eth_blockNumber").toString()));
- // 查询数据库中存储的最新区块数据
- int blockNumberDataSource = blockMapper.getBlockNum();
- for (int i = blockNumberDataSource + 1; i <= blockNumberNew; i++) {
- asyncTranscationTask.insertTransTask(i);
- }
- } catch (Throwable throwable) {
- throwable.printStackTrace();
- }
- }
- }
启动程序中需要加上@EnableScheduling注解启动定时任务探测。
多线程
Spring Boot有自己默认的线程池,这里我们自定义一个自己的线程池。
配置线程池:
- package com.example.theadPoolConfig;
- /**
- * Created by wuhaochao on 2017/7/25.
- */
- import org.springframework.context.annotation.Bean;
- import org.springframework.context.annotation.Configuration;
- import org.springframework.scheduling.annotation.EnableAsync;
- import org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor;
- import java.util.concurrent.Executor;
- import java.util.concurrent.ThreadPoolExecutor;
- /**
- * 创建自定义线程池
- */
- @Configuration
- @EnableAsync
- public class TaskExecutePool {
- @Bean
- public Executor myTaskAsyncPool() {
- ThreadPoolTaskExecutor executor = new ThreadPoolTaskExecutor();
- executor.setCorePoolSize(10);
- executor.setMaxPoolSize(50);
- executor.setQueueCapacity(1000);
- executor.setKeepAliveSeconds(300);
- // rejection-policy:当pool已经达到max size的时候,如何处理新任务
- // CALLER_RUNS:不在新线程中执行任务,而是由调用者所在的线程来执行
- executor.setRejectedExecutionHandler(new ThreadPoolExecutor.CallerRunsPolicy());
- executor.initialize();
- return executor;
- }
- }
使用自定义线程池:
- package com.example.theadPoolConfig;
- import com.example.entity.BlockInfoBean;
- import com.example.entity.TranscationBean;
- import com.example.mapper.BlockMapper;
- import com.example.mapper.TranscationMapper;
- import com.example.unitl.Until;
- import net.sf.json.JSONArray;
- import net.sf.json.JSONObject;
- import org.slf4j.Logger;
- import org.slf4j.LoggerFactory;
- import org.springframework.beans.factory.annotation.Autowired;
- import org.springframework.scheduling.annotation.Async;
- import org.springframework.stereotype.Component;
- import java.util.ArrayList;
- import java.util.List;
- /**
- * Created by wuhaochao on 2017/7/25.
- */
- @Component
- public class AsyncTranscationTask {
- private static final Logger logger = LoggerFactory.getLogger(AsyncTranscationTask.class);
- @Autowired
- private TranscationMapper transcationMapper;
- @Autowired
- private BlockMapper blockMapper;
- //myTaskAsynPool即配置线程池的方法名,此处如果不写自定义线程池的方法名,会使用默认的线程池
- @Async("myTaskAsyncPool")
- public void insertTransTask(int i) throws InterruptedException {
- logger.info("TranscationTask" + i + " started.");
- //开始导入交易信息
- String method_BlockByNumber = "eth_getBlockByNumber";
- JSONObject objects = null;
- List<TranscationBean> list = null;
- JSONObject transtionObject = null;
- TranscationBean transcation = null;
- try {
- objects = JSONObject.fromObject(Until.JSONRPCClient(new Object[]{i, true}, method_BlockByNumber));
- } catch (Throwable throwable) {
- throwable.printStackTrace();
- }
- //插入区块信息
- BlockInfoBean blockInfoBean = new BlockInfoBean(objects);
- blockMapper.insertBlockInfo(blockInfoBean);
- if (JSONArray
- .fromObject(objects.get("transactions")).size() > 0) {
- list = new ArrayList<TranscationBean>();
- for (java.util.Iterator tor = JSONArray
- .fromObject(objects.get("transactions"))
- .iterator(); tor.hasNext(); ) {
- transtionObject = (JSONObject) tor.next();
- transcation = new TranscationBean(transtionObject);
- transcation.setTimestamp(Until.formatTimeMillis(objects.get("timestamp").toString()));
- list.add(transcation);
- }
- //批量插入
- transcationMapper.insertTranscationList(list);
- }
- }
- }
