Spring+mybatis的线程池具体用法
web工程中非常的简单的。
一、xml配置
applicationContext-threadpool.xml

<?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:context="http://www.springframework.org/schema/context"  xsi:schemaLocation="  http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  http://www.springframework.org/schema/context                http://www.springframework.org/schema/context/spring-context-3.0.xsd">    <!-- 异步线程池 --> <bean id="taskExecutor"      class="org.springframework.scheduling.concurrent.ThreadPoolTaskExecutor">      <!-- 核心线程数 -->      <property name="corePoolSize" value="10" />      <!-- 最大线程数 -->      <property name="maxPoolSize" value="20" />      <!-- 队列最大长度 >=mainExecutor.maxSize -->      <property name="queueCapacity" value="30" />      <!-- 线程池维护线程所允许的空闲时间 -->      <property name="keepAliveSeconds" value="300" />      <!-- 线程池对拒绝任务(无线程可用)的处理策略 -->      <property name="rejectedExecutionHandler">          <bean class="java.util.concurrent.ThreadPoolExecutor$CallerRunsPolicy" />      </property>  </bean>    </beans>

web.xml配置

 <context-param>    <param-name>contextConfigLocation</param-name>    <param-value>           /WEB-INF/config/spring/applicationContext-*.xml        </param-value> </context-param>

二、使用方法

ServiceImpl代码：

@Servicepublic class SpringThreadPoolServiceImpl implements SpringThreadPoolService {    @Resource(name = "taskExecutor")    private TaskExecutor taskExecutor;    @Autowired    private IService service;    @Override    public void process(Version a) {         // 使用多线程处理        taskExecutor.execute(new Runnable() {            @Override            public void run() {                    service.insert(a);                    System.out.println("[Thread " + Thread.currentThread().getId() + " start]\t"+Thread.currentThread().getName()+"\t处理结果"+j);            }        });    }}

Controller代码：

    @RequestMapping(value = "/insert", method = {            RequestMethod.POST, RequestMethod.GET }, produces = "text/html;charset=UTF-8")    public @ResponseBody String SpringThreadPoolInsert(Version version) throws Exception {              System.out.println("开始啦");        List<Version> insertList = produceList(version);//产生若干的Version        System.out.println(insertList.size());        for(version aaa:insertList){            springThreadPoolService.process(aaa);        }               return "结束了";    }

然后启动web工程
用浏览器访问insert接口即可看见飞一般的速度。
请测可用！
