第一步:新建任務執行類java
package group.esperanto.util; import java.text.SimpleDateFormat; import java.util.Date; public class MyTask3 { public void excJob() { System.out.println("當前日期: " + new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())); } }
第二步:修改applicationContext文件spring
<?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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:task="http://www.springframework.org/schema/task" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.1.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.0.xsd "> </beans>
第三步:配置定時觸發或間隔觸發spring-mvc
<bean id="myTask" class="cn.mldn.util.MyTask3"/> <task:scheduled-tasks> <!-- 間隔觸發 --> <!-- <task:scheduled ref="myTask" method="excJob" fixed-rate="2000"/> --> <!-- 定時觸發 --> <task:scheduled ref="myTask" method="excJob" cron="* * * * * ?"/> </task:scheduled-tasks>
