一个简单的基于spring mvc的定时器

所需最少jar

web.xml配置:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

    <!--Spring ApplicationContext 载入 -->
    <listener>
        <listener-class>
            org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    
    <!-- Spring ApplicationContext配置文件的路径*,可使用通配符，多个路径用*号分隔
        此参数用于后面的Spring-Context loader -->
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:com/timer/config/applicationContext.xml</param-value>
    </context-param>
</web-app>

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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:task="http://www.springframework.org/schema/task"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
       http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

       http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd"
       default-autowire="byName" default-lazy-init="false">
        
    <!-- 定时器开关-->
    <task:annotation-driven />   
    <!-- 启动Spring MVC的注解功能，完成请求和注解POJO的映射 -->
    <mvc:annotation-driven />
    
    <context:component-scan base-package="com.timer" />
</beans>

定时器类：

package com.timer.controller;

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

@Component
public class TimerController {
    
    /**  
     * 每天凌晨清空所有用户分享数据
     */    
    @Scheduled(cron = "0 53 17 * * ?")   
    public void clearCustomerShare(){  
        System.out.println("========================sys");
    }  
}

//==========================cron表达式：http://rainbowdesert.iteye.com/blog/2107220

由6-7个组成

秒-分-时  天-月-日-年 用空格分开
