=========================================两种方式:
01:基于注解
利用spring中的以下配置
<task:annotation-driven /> <!-- 定时器开关-->
- <!-- 自动扫描的包名 -->
- <context:component-scan base-package="com.spring.task" />
- 类注解:
- @Component
- 方法注解:
- @Scheduled(cron = "0 0 1 * * *")
----------------------------------------------------------------------------------
- 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
- */
- @Component
- public 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");
- }
- }
02:基于xml
利用spring中的以下配置
- <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>
- 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");
- }
- }
