Spring Task Demo .

一.web.xml

<context-param><param-name>contextConfigLocation</param-name><param-value>classpath:application*.xml</param-value></context-param><listener>    <description>Spring监听器</description>    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>

二.执行任务的普通Java类.

package com.test.service;import org.springframework.stereotype.Service;@Service("taskJob") public class TaskJob {public void job1(){System.out.println("任务一进行中...");}public void job2(){System.out.println("任务二进行中...");}public TaskJob() {super();System.out.println("业务类加载完成...");}}

三.applicationContext.xml.

 <!-- 支持注解 --> <context:annotation-config />  <!-- 启动自动扫描,不扫描@Controller,该组件由SpringMVC配置文件扫描 --> <context:component-scan base-package="com.test.service" />  <task:scheduled-tasks>        <task:scheduled ref="taskJob" method="job1" cron="0/5 * * * * ?"/>          <task:scheduled ref="taskJob" method="job2" cron="0/5 * * * * ?"/>      </task:scheduled-tasks>  

四.启动项目

信息: At least one JAR was scanned for TLDs yet contained no TLDs. Enable debug logging for this logger for a complete list of JARs that were scanned but no TLDs were found in them. Skipping unneeded JARs during scanning can improve startup time and JSP compilation time.
