Spring注解@Scheduled定时任务

一、首先配置applicationContext-task.xml

　　(1)添加 xmlns:task="http://www.springframework.org/schema/task"

　　(2)添加 xsi:schemaLocation="http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd"

　　------- applicationContext-task.xml文件 --------

<?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"
    xmlns:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
            http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.1.xsd
            http://www.springframework.org/schema/task
            http://www.springframework.org/schema/task/spring-task-3.0.xsd">
    <description>spring task定时任务</description>
    <!-- 定时任务配置 scheduler 方式 注解  -->
    <context:component-scan base-package="com.lwj.task" />
    <task:executor id="executor" pool-size="5" />
    <task:scheduler id="scheduler" pool-size="10" />
    <task:annotation-driven executor="executor"
        scheduler="scheduler" />
</beans>

二、配置applicationContext.xml文件

　　------- applicationContext.xml文件 --------

<?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-3.1.xsd
            http://www.springframework.org/schema/context
            http://www.springframework.org/schema/context/spring-context-3.1.xsd">
    <!-- 开启注解扫描 -->
    <context:annotation-config />

    <!--引入配置属性文件 -->
    <context:property-placeholder location="classpath:config.properties" />

    <!--自动扫描含有@Service将其注入为bean 和@Repository注入 -->
    <context:component-scan base-package="com.lwj.service,com.lwj.dao" />
    <!-- 定时任务 -->
    <import resource="applicationContext-task.xml" />
</beans>

三、编写TimeTask.java

　　------- TimeTask.java文件 --------

package com.lwj.task;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

/**
 *
 * @Description : 定时任务
 * @author : lwj
 * @version : 1.0
 * @Date : 2016年4月7日 上午8:56:00
 */
@Component
public class TimeTask {
    @Scheduled(cron="0/10 * * * * *")
    public void Test(){
        System.out.println("每10秒执行一次任务！");
    }
}
