spring定时任务的配置式与注解式

在定时任务配置文件中添加内容:

<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:task="http://www.springframework.org/schema/task"    xmlns:context="http://www.springframework.org/schema/context"    xmlns:aop="http://www.springframework.org/schema/aop"     xsi:schemaLocation="http://www.springframework.org/schema/beans     http://www.springframework.org/schema/beans/spring-beans-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/jee http://www.springframework.org/schema/jee/spring-jee-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/task http://www.springframework.org/schema/task/spring-task-3.0.xsd">    <task:annotation-driven /> <!-- 定时器开关-->    <bean id="myTaskXml" class="com.spring.task.MyTaskXml"></bean>    <task:scheduled-tasks>        <!--             这里表示的是每隔五秒执行一次         -->        <task:scheduled ref="myTaskXml" method="show" cron="*/5 * * * * ?" />        <task:scheduled ref="myTaskXml" method="print" cron="*/10 * * * * ?"/>    </task:scheduled-tasks>        <!-- 自动扫描的包名 -->      <context:component-scan base-package="com.spring.task" />    </beans>

 

如果是配置式的定时任务:

package com.spring.task;/** * 基于xml的定时器 * @author hj */public class MyTaskXml {            public void show(){        System.out.println("XMl:is show run");    }        public void print(){        System.out.println("XMl:print run");    }}

 

 

如果是注解式的定时任务:

package com.spring.task;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Component;/** * 基于注解的定时器 * @author hj */@Componentpublic class MyTaskAnnotation {        /**      * 定时计算。每天凌晨 01:00 执行一次      */      @Scheduled(cron = "0 0 1 * * *")     public void show(){        System.out.println("Annotation:is show run");    }        /**      * 心跳更新。启动时执行一次,之后每隔2秒执行一次      */      @Scheduled(fixedRate = 1000*2)     public void print(){        System.out.println("Annotation:print run");    }}

测试:

package com.spring.test;import org.springframework.context.ApplicationContext;import org.springframework.context.support.ClassPathXmlApplicationContext;public class Main {    public static void main(String[] args) {        ApplicationContext ctx = new ClassPathXmlApplicationContext("spring-mvc.xml");    }}
