Spring定时器实现(一)

Spring定时器简单应用实现，如下：

首先、Spring配置文件：

<?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:task="http://www.springframework.org/schema/task"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-4.3.xsd
        http://www.springframework.org/schema/task
        http://www.springframework.org/schema/task/spring-task-4.3.xsd ">

    <description>spring-configuration</description>

    <bean id="timerTask" class="com.charles.spring.service.impl.TimerTaskImpl"></bean>

    <task:scheduled-tasks>
        <task:scheduled ref="timerTask" method="doTimerTask" cron="0/5 * * * * ?" />
    </task:scheduled-tasks>

</beans>

其次、相关定时器接口(忽略不计，只是定义一个方法)、类：

package com.charles.spring.service.impl;

import com.charles.spring.service.TimerTask;

public class TimerTaskImpl implements TimerTask {

    @Override
    public void doTimerTask() throws Exception {
        System.out.println("Hello Timer");
    }

}

最后测试，测试项目是Java项目，所以只需要加载Spring就可以了，如下：

package com.charles.spring.handler;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Timer {

    public static void main(String[] args) {

        @SuppressWarnings({ "unused", "resource" })
        ApplicationContext context = new ClassPathXmlApplicationContext("config/spring-config.xml");
        try {
            Thread.sleep(10*60*1000);
        } catch (Exception e) {

        }

    }

}

结束。结果：
