有时候我们的任务(Job)需要再某些任务完成之后才能进行；例如从旧的数据库批量导数据的时候；需要现将被其他数据依赖的数据导入新的数据库；然后再进行关系的导入.。在这种情况下我们就可以使用Quartz的listener来做文章了。

首先我们写一个主任务的类，命名为MainJob；她的作用是作为一系列任务的开始点。
MainJob.java

package com.zuidaima.quartz.jobs; import org.apache.log4j.Logger; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; import org.springframework.scheduling.quartz.QuartzJobBean; public class MainJob extends QuartzJobBean { private Logger logger=Logger.getLogger(getClass()); @Override protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException { // TODO Auto-generated method stub logger.debug("Just say hi."); }}

然后我们新建另外一个任务（SecondJob）作为后续任务：
SecondJob.java

package com.zuidaima.quartz.jobs; import org.apache.log4j.Logger; import org.quartz.JobExecutionContext; import org.quartz.JobExecutionException; import org.springframework.scheduling.quartz.QuartzJobBean; public class SecondJob extends QuartzJobBean { private Logger logger=Logger.getLogger(getClass()); @Override protected void executeInternal(JobExecutionContext arg0) throws JobExecutionException { // TODO Auto-generated method stub logger.debug("I'm the second job."); }}

创建一个TriggerListener,重写其triggerComplete方法，并且添加一些方便spring注入的属性和方法。
NextJobTriggerListener.java

package com.zuidaima.listeners; import org.apache.log4j.Logger; import org.quartz.JobDetail; import org.quartz.JobExecutionContext; import org.quartz.Scheduler; import org.quartz.Trigger; import org.quartz.listeners.TriggerListenerSupport; import org.springframework.scheduling.quartz.QuartzJobBean; import org.springframework.scheduling.quartz.SimpleTriggerBean; public class NextJobTriggerListener extends TriggerListenerSupport { private Logger logger=Logger.getLogger(getClass()); private String name; public String getName() { return this.name; } public void setName(String name) { this.name=name; } private SimpleTriggerBean nextTrigger; public void setNextTrigger(SimpleTriggerBean nextTrigger) { this.nextTrigger=nextTrigger; } @Override public void triggerComplete(Trigger trigger, JobExecutionContext context, int code) { try{ Scheduler schduler=context.getScheduler(); JobDetail nextJob=nextTrigger.getJobDetail(); //查找名称和即将加入的任务一样的任务 JobDetail oldJob=schduler.getJobDetail(nextJob.getName(),nextJob.getGroup()); //查找名称和即将加入的触发器一样的触发器 Trigger oldTrigger=schduler.getTrigger(nextTrigger.getName(),nextTrigger.getGroup());  if(oldJob==null&&oldTrigger==null)//同名的任务和触发器都不存在 { logger.debug("inside scheduleJob."+code); schduler.scheduleJob(nextJob,nextTrigger); }else//同名的任务或触发器 {  logger.debug("oldJob==null:"+(oldJob==null)); logger.debug("oldTrigger==null:"+(oldTrigger==null));  } super.triggerComplete(trigger, context, code); }catch(Exception e) { e.printStackTrace(); } } }

配置spring 的applicationContext.xml
applicationContext.xml

<?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:jee="http://www.springframework.org/schema/jee" xsi:schemaLocation="http://www.springframework.org/schema/beanshttp://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-2.0.xsd">  <!-- 主任务 -->  <bean id="mainJob" class="org.springframework.scheduling.quartz.JobDetailBean"> <!-- 运行的类 -->  <property name="jobClass"> <value> jobs.MainJob </value>  </property>  </bean>   <!-- 主任务的监听器 -->  <bean id="mainTriggerListener" class="listeners.NextJobTriggerListener"> <!-- 下个触发器 -->  <property name="nextTrigger" ref="secondTrigger"></property> <!-- 监听器名称 -->  <property name="name" value="mainTriggerListener"></property> </bean>  <!-- 主任务的触发器 -->  <bean id="mainTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail"> <!-- 上面创建的任务调度对象 -->  <ref bean="mainJob" />  </property>  <!-- 启动60秒后执行任务调度的excute方法 -->  <property name="startDelay"> <value> 6000 </value>  </property>  <!-- 运行次数 -->  <property name="repeatCount"> <value> </value>  </property>  <!-- 隔一个小时运行一次(貌似多余,不写会报错) -->  <property name="repeatInterval"> <value> 3600000 </value>  </property>  <property name="triggerListenerNames"> <list>  <value> mainTriggerListener </value>  </list>  </property>  </bean>   <!-- 后续任务 -->  <bean id="secondJob" class="org.springframework.scheduling.quartz.JobDetailBean"> <!-- 运行的类 -->  <property name="jobClass"> <value> jobs.SecondJob </value>  </property>  </bean>  <!-- 后续任务的触发器 -->  <bean id="secondTrigger" class="org.springframework.scheduling.quartz.SimpleTriggerBean"> <property name="jobDetail"> <!-- 上面创建的任务调度对象 -->  <ref bean="secondJob" />  </property>  <!-- 启动6秒后执行任务调度的excute方法 -->  <property name="startDelay"> <value> 6000 </value>  </property>  <!-- 运行次数 -->  <property name="repeatCount"> <value> </value>  </property>  <!-- 隔一个小时运行一次(貌似多余,不写会报错) -->  <property name="repeatInterval"> <!--  <value>3600000</value> -->  <value> 6000 </value>  </property>  </bean>   <!-- 任务调度工厂类 -->  <bean class="org.springframework.scheduling.quartz.SchedulerFactoryBean"> <!-- 这一部分的配置不用管 -->  <property name="quartzProperties"> <props>  <prop key="org.quartz.threadPool.class"> org.quartz.simpl.SimpleThreadPool </prop>  <prop key="org.quartz.threadPool.threadCount"> </prop>  <prop key="org.quartz.threadPool.threadPriority"> 5 </prop>  <prop key="org.quartz.threadPool.threadsInheritContextClassLoaderOfInitializingThread"> true </prop>  </props>  </property>  <!-- 触发器,可以放一大堆触发器 -->  <property name="triggers"> <list>  <!-- 在这里加 -->  <ref bean="mainTrigger"/>  </list>  </property>  <property name="triggerListeners"> <list>  <!-- 触发器的监听器 -->  <ref bean="mainTriggerListener" />  </list>  </property>  </bean>  </beans> 

开启服务器，输出

DEBUG [ MainJob.executeInternal(14) ] Just say hi.DEBUG [ NextJobTriggerListener.triggerComplete(38) ] inside scheduleJob .3 DEBUG [SecondJob.executeInternal(14)] I'm the second job.DEBUG [ NextJobTriggerListener.triggerComplete(43) ] oldJob==null:falseDEBUG [ NextJobTriggerListener.triggerComplete(44) ] oldTrigger== null:false

另外这里一个任务只绑定了一个简单的触发器，这样做是为了比较方便地可以检测到任务完成的情况；至于任务的具体内容就任由大家发挥了。写这篇文章希望能有人在其中获得启发。
