好记性不如烂博客之 Quartz How-To: Using Trigger Listeners

How-To: Using Trigger Listeners

 

Creating a TriggerListener

Implement the TriggerListener interface.

package foo;



import org.quartz.JobExecutionContext;

import org.quartz.Trigger;

import org.quartz.TriggerListener;

import org.quartz.Trigger.CompletedExecutionInstruction;



public class MyTriggerListener implements TriggerListener {



    private String name;



    public MyTriggerListener(String name) {

        this.name = name;

    }

    

    public String getName() {

        return name;

    }



    public void triggerComplete(Trigger trigger, JobExecutionContext context,

            CompletedExecutionInstruction triggerInstructionCode) {

        // do something with the event

        

    }



    public void triggerFired(Trigger trigger, JobExecutionContext context) {

        // do something with the event

    }



    public void triggerMisfired(Trigger trigger) {

        // do something with the event

    }



    public boolean vetoJobExecution(Trigger trigger, JobExecutionContext context) {

        // do something with the event

        return false;

    }



}

OR -

Extend TriggerListenerSupport.

package foo;



import org.quartz.JobExecutionContext;

import org.quartz.Trigger;

import org.quartz.listeners.TriggerListenerSupport;



public class MyOtherTriggerListener extends TriggerListenerSupport {



    private String name;



    public MyOtherTriggerListener(String name) {

        this.name = name;

    }

   

    public String getName() {

        return name;

    }



    @Override

    public void triggerFired(Trigger trigger, JobExecutionContext context) {

        // do something with the event

    }

}

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"));
