Spring Scheduled Task polling (spring Task)

Scheduled task polling such as a task starts running from the server and executes every 5 seconds.

The following is a scheduled task configured with spring annotations.
1, add the corresponding schema

1234	xmlns:task="xsi:schemaLocation="    http://www.springframework.org/schema/task     http://www.springframework.org/schema/task/spring-task-3.0.xsd"

　　

The complete schema is as follows:

12345678910111213

<beans xmlns="http://www.springframework.org/schema/beans"    xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"    xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"    xmlns:task="http://www.springframework.org/schema/task"    xsi:schemaLocation="http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context.xsd        http://www.springframework.org/schema/mvc        http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd      http://www.springframework.org/schema/task                http://www.springframework.org/schema/task/spring-task-3.0.xsd"></beans>

　　

2. Configure automatic dispatch of the package and timing switch

123456

<!-- 注解扫描包 --><context:component-scanbase-package="com.ljq.web.controller.annotation" /><!-- Enables the Spring Task @Scheduled programming model --><task:executor id="executor" pool-size="5" /> <task:scheduler id="scheduler" pool-size="10" /> <task:annotation-drivenexecutor="executor" scheduler="scheduler" />

　　

3. Add the Dispatch test class

123456789101112131415161718

package com.ljq.web.controller.annotation;import org.springframework.scheduling.annotation.Scheduled;import org.springframework.stereotype.Service;/** * 调度测试类(每隔5秒执行一次) *  * @author Administrator * */@Servicepublic class TaskTest {    @Scheduled(cron = "0/5 * * * * ? ")    public void myTestWork() {        System.out.println(System.currentTimeMillis());    }}

　　

Note: cron = "0/5 * * * * *?" From left to right: seconds, minutes, hours, days, months, weeks, years
