[Spring] - Quartz定时任务 - Annotation
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;@Componentpublic 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:
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。
