本文介绍如何使用Spring 3.X版本进行定时任务的配置与实现。通过定义注解和配置XML文件，可以轻松设置每五秒执行一次的任务，展示具体的时间打印实例。

1、创建定时任务


package com.*.task;

import java.util.Date;

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

import com.*.core.util.DateUtil;

/**
 * Description : TODO 

 * Create Time : 2013年11月28日 下午4:16:03 

 * Copyright : Copyright (c) 2010 - 2013 All rights reserved. 

 * 
 * @author Mr Yan
 * @version 1.0
 */
@Component
public class TaskDemo {

	/**
	 * 打印时间（每五秒打印一次）
	 */
	@Scheduled(cron="0/5 * * * * ?")
	public void printTime(){
		System.out.println(DateUtil.format(new Date(), "yyyyMMddHHmmss"));
	}

}

2、配置applicationContext.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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
	xmlns:task="http://www.springframework.org/schema/task"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
	http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd   
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
    http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">

	<!-- 定时任务驱动注册（注解） -->
	<task:annotation-driven />

</beans>


<?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:p="http://www.springframework.org/schema/p"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx"
	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
	http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd   
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">

	<!-- load application context file -->

	<import resource="applicationContext-task.xml"/>
</beans>
