定时任务（2）

定时任务注解方式：

application2.xml

<?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:aop="http://www.springframework.org/schema/aop"     xmlns:task="http://www.springframework.org/schema/task"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/aop        http://www.springframework.org/schema/aop/spring-aop.xsd        http://www.springframework.org/schema/task        http://www.springframework.org/schema/task/spring-task.xsd">     <!-- 方式二： 开启IOC注解扫描 -->     <context:component-scan base-package="com"/>     <!-- 配置定时任务驱动 开启这个配置，spring才能识别 @Scheduled-->      <task:annotation-driven/> </beans>

TaskJob2:

package com.java.task; import java.text.SimpleDateFormat; import java.util.Date; import org.springframework.scheduling.annotation.Scheduled; import org.springframework.stereotype.Component; @Component public class TaskJob2 {     private SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");         //定义定时任务方法     @Scheduled(cron="0/2 * * * * ?")     public void job1() {         System.out.println("定时任务1..."+sdf.format(new Date()));     }     @Scheduled(cron="0/5 * * * * ?")     public void job2() {         System.out.println("定时任务2..."+sdf.format(new Date()));     } }

ApplicationTest2:

package com.java.app; import org.springframework.context.ApplicationContext; import org.springframework.context.support.ClassPathXmlApplicationContext; import com.java.task.TaskJob2; public class ApplicationTest2 {     public static void main(String[] args) {         ApplicationContext ac=new ClassPathXmlApplicationContext("application.xml");         TaskJob2 job=(TaskJob2)ac.getBean("taskJob2");         } }

输出：

定时任务2...2021-06-08 19:09:55 定时任务1...2021-06-08 19:09:56 定时任务1...2021-06-08 19:09:58 定时任务2...2021-06-08 19:10:00 定时任务1...2021-06-08 19:10:00 定时任务1...2021-06-08 19:10:02 定时任务1...2021-06-08 19:10:04 定时任务2...2021-06-08 19:10:05
