spring quartz定时任务配置【基础篇】

一个定时执行的job

package dk.spring.quartz;

import java.util.Date;

import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.springframework.scheduling.quartz.QuartzJobBean;

/**
 * 使用spring集成的quartz调度
 */
public class QuartzTestJob extends QuartzJobBean {

	/**
	 * 执行任务
	 */
	protected void executeInternal(JobExecutionContext arg0)
			throws JobExecutionException {
		System.out.println("QuartzTestJob start:"+new Date());
	}
}

一个定时调度的配置schedules.xml

<?xml version="1.0"?>
<beans xmlns="http://www.springframework.org/schema/beans" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:context="http://www.springframework.org/schema/context"  
 xmlns:jee="http://www.springframework.org/schema/jee" 
 xsi:schemaLocation="
 http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
 http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.2.xsd
 http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.2.xsd"

	<!-- 任务明细bean,对quartz任务包装 -->
	<bean id="jobDetailBean" class="org.springframework.scheduling.quartz.JobDetailBean">
		<property name="jobClass"	value="dk.spring.quartz.QuartzTestJob" />
	</bean>

	<!-- cron触发器bean,设置任务的调度策略的 -->
	<bean id="cronTriggerBean" class="org.springframework.scheduling.quartz.CronTriggerBean">
		<property name="jobDetail" ref="jobDetailBean" />
		<!-- cron表达式 -->
		<property name="cronExpression">
			<value>0/5 * * * * ?</value>
		</property>
	</bean>

	<!-- 调度器工厂bean,激活触发器,启动quartz任务的 -->
	<bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean">
		<property name="triggers">
			<ref bean="cronTriggerBean" />
		</property>
	</bean>
</beans>

web.xml要记得加载schedules.xml

<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>
			classpath*:/applicationContext.xml;classpath:schedules.xml
		</param-value>
</context-param>

运行web工程结果如下：

QuartzTestJob start:Sun Sep 21 16:15:15 CST 2014
QuartzTestJob start:Sun Sep 21 16:15:20 CST 2014
QuartzTestJob start:Sun Sep 21 16:15:25 CST 2014
