Quartz TriggerListener 触发器监听器

Quartz  Scheduler 可以对Trigger建立一个监听器，分别对Trigger的各种状态进行监听

实现监听器需要实现TriggerListener接口，然后注册到Scheduler上就可以了。

一：写一个类实现触发器监听接口

package com.gary.operation.jobdemo.example1; import org.quartz.JobExecutionContext; import org.quartz.Trigger; import org.quartz.Trigger.CompletedExecutionInstruction; import org.quartz.TriggerListener; public class MyTriggerListener implements TriggerListener { @Override public String getName() { return "MyOtherTriggerListener"; } /** * (1) * Trigger被激发 它关联的job即将被运行 * Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed. */ @Override public void triggerFired(Trigger trigger, JobExecutionContext context) { System.out.println("MyOtherTriggerListener.triggerFired()"); } /** * (2) * Trigger被激发 它关联的job即将被运行,先执行(1)，在执行(2) 如果返回TRUE 那么任务job会被终止 * Called by the Scheduler when a Trigger has fired, and it's associated JobDetail is about to be executed */ @Override public boolean vetoJobExecution(Trigger trigger, JobExecutionContext context) { System.out.println("MyOtherTriggerListener.vetoJobExecution()"); return false; } /** * (3) 当Trigger错过被激发时执行,比如当前时间有很多触发器都需要执行，但是线程池中的有效线程都在工作， * 那么有的触发器就有可能超时，错过这一轮的触发。 * Called by the Scheduler when a Trigger has misfired. */ @Override public void triggerMisfired(Trigger trigger) { System.out.println("MyOtherTriggerListener.triggerMisfired()"); } /** * (4) 任务完成时触发 * Called by the Scheduler when a Trigger has fired, it's associated JobDetail has been executed * and it's triggered(xx) method has been called. */ @Override public void triggerComplete(Trigger trigger, JobExecutionContext context, CompletedExecutionInstruction triggerInstructionCode) { System.out.println("MyOtherTriggerListener.triggerComplete()"); } }

 

二进行注册: 细节与注册任务监听器一样(http://www.cnblogs.com/daxin/archive/2013/05/29/3105830.html)

Registering A TriggerListener With The Scheduler To Listen To All Triggers scheduler.getListenerManager().addTriggerListener(myTriggerListener, allTriggers()); Registering A TriggerListener With The Scheduler To Listen To A Specific Trigger scheduler.getListenerManager().addTriggerListener(myTriggerListener, triggerKeyEquals(triggerKey("myTriggerName", "myTriggerGroup"))); Registering A TriggerListener With The Scheduler To Listen To All Triggers In a Group scheduler.getListenerManager().addTriggerListener(myTriggerListener, triggerGroupEquals("myTriggerGroup"));
