quartz

一个定时执行的job

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

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

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

<? 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

?

1 2 3 4 5 6

< 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
