Spring通过注解方式实现定时任务

XML配置：

 <?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-3.2.xsd
         http://www.springframework.org/schema/context
         http://www.springframework.org/schema/context/spring-context-3.2.xsd
         http://www.springframework.org/schema/task
         http://www.springframework.org/schema/task/spring-task-3.2.xsd ">
     <!-- 扫描包基础目录 -->
     <context:component-scan base-package="com.wisezone" />
     <!-- 识别@Scheduled注解 -->
     <task:annotation-driven/>  
 
 </beans>

java代码：

 package com.wisezone.service;
 
 import java.text.SimpleDateFormat;
 import java.util.Date;
 
 import org.springframework.scheduling.annotation.Scheduled;
 import org.springframework.stereotype.Service;
 
 @Service
 public class JobService {
 
     @Scheduled(cron="0/2 * * * * ?")
     public void job(){
         System.out.println("定时输出任务："+new SimpleDateFormat("yyyy-MM-dd hh:mm:ss").format(new Date()));
     }
 }

测试类：

 package com.wisezone.test;
 
 import org.springframework.context.ApplicationContext;
 import org.springframework.context.support.ClassPathXmlApplicationContext;
 
 public class Test
 {
     public static void main(String[] args)
     {
         ApplicationContext app = new ClassPathXmlApplicationContext("beans.xml");
 
     }
 } 

结果：
