[Spring] - Quartz定时任务 - Annotation

时间:2022-11-15 18:13:14

Spring + Quartz可以使用annoation方式:

1、AppJob类:

package com.my.quartz.testquartz1;

import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component; @Component
public class AppJob { // @Scheduled(fixedDelay=1000) //第一种方式
// fixedDelay延时多少毫秒,多少毫秒执行一次
/*
1 Seconds (0-59)
2 Minutes (0-59)
3 Hours (0-23)
4 Day of month (1-31)
5 Month (1-12 or JAN-DEC)
6 Day of week (1-7 or SUN-SAT)
7 Year (1970-2099)
取值:可以是单个值,如6;
也可以是个范围,如9-12;
也可以是个列表,如9,11,13
也可以是任意取值,使用*
*/
// 0 * * * * * 代表每分钟执行一次
/*
2011-09-07 09:23:00
2011-09-07 09:24:00
2011-09-07 09:25:00
2011-09-07 09:26:00
*/
@Scheduled(cron="0/1 * * * * ?")
public void execute() {
long ms = System.currentTimeMillis();
System.out.println(ms);
} }

cron的写法,可参见:

2、Spring配置文件:

<?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:tx="http://www.springframework.org/schema/tx"
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"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/task
http://www.springframework.org/schema/task/spring-task-3.0.xsd"> <!--注解说明 -->
<context:annotation-config />
<!-- Spring自动扫描包 -->
<context:component-scan base-package="com.my" /> <!-- 计划任务 -->
<task:executor id="executor" pool-size="5" />
<task:scheduler id="scheduler" pool-size="10" />
<task:annotation-driven executor="executor" scheduler="scheduler" /> </beans>

3、运行类:

package com.my.quartz.testquartz1;

import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext; public class App
{
@SuppressWarnings("resource")
public static void main( String[] args ) throws InterruptedException, SchedulerException
{
ApplicationContext context = new ClassPathXmlApplicationContext("spring.xml");
System.out.println("Job-End");
//Scheduler scheduler = (Scheduler) context.getBean("schedulerBean");
//scheduler.shutdown();
}
}

运行结果:

[Spring] - Quartz定时任务 - Annotation


当然,Spring的配置文件也可以这样写:

    <!-- 定时器开关-->
<task:annotation-driven />
<!-- 管理的Bean -->
<bean id="appJob" class="com.my.quartz.testquartz1" />
<task:scheduled-tasks scheduler="task">
<!--每三秒执行一次 -->
<task:scheduled ref="appJob" method="execute"
cron="0/1 * * * * ?" />
</task:scheduled-tasks>
<task:scheduler id="task" pool-size="10" />

这样写是可配置的,使用Annotation方式是编译式的。
