Spring uses annotations to perform timed tasks

Add the following configuration in a Springcontext.xml

1. Beans Add Xmlns:task

xmlns:task= "Http://www.springframework.org/schema/task"

2. Add in Xsi:schemalocation

Http://www.springframework.org/schema/taskhttp://www.springframework.org/schema/task/spring-task-3.0.xsd

3. Adding beans and task labels

<task:annotation-driven/><bean class= " Org.springframework.beans.factory.annotation.AutowiredAnnotationBeanPostProcessor "/>

4. Add a scan Package

<context:component-scan base-package= "Com.task.springTask"/>

Two timed Tasks Java code

Package Com.task.springtask;import Org.springframework.scheduling.annotation.scheduled;import org.springframework.stereotype.Component; @Component ("Springtask") public class Springtask {    @Scheduled (cron = "0 /2 * * * * *?)    public void MyTask () {        System.out.println ("This task executes once in two seconds! ");    }}

Execution effect

Description :
