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：
