Java – spring: how to monitor quartz jobs from the controller?

I created two jobs in the spring project, which run independently of each other at two different times

public class JobA extends QuartzJobBean
{
    @Override
    protected void executeInternal(JobExecutionContext arg0)throws JobExecutionException 
    {
      // my actual work
    }
}

and

public class JobB extends QuartzJobBean
{
    @Override
    protected void executeInternal(JobExecutionContext arg0)throws JobExecutionException 
    {
      // my actual work
    }
}

Both run normally at a given time, but I need to provide some monitoring functions through which we can check whether the job is running I met joblistener and saw other resources, but I was confused when I implemented it I don't know exactly how to use this listener in spring controller so that I can monitor these two jobs in my JSP

Update: I'm using quartz 1.8 How do I check if any work has stopped? How can we restart any work that is stopped or destroyed?

Solution

You can easily retrieve the job trigger status

Quartz 2 Example of X:

// get the scheduler factory bean from the spring context
Scheduler scheduler = (Scheduler) getApplicationContext().getBean("schedulerfactorybean");
// get the TriggerKey 
TriggerKey triggerKey = TriggerKey.triggerKey("servicecrontrigger");
// get the state from the triggerKey
TriggerState triggerState = scheduler.getTriggerState(triggerKey);

For quartz 1.8

According to the API documentation, scheduler Gettriggerstate (string triggername, string triggergroup) can tell you the status of a specific trigger and return one of the following constants: trigger STATE_ NORMAL,Trigger. STATE_ PAUSED,Trigger. STATE_ COMPLETE,Trigger. STATE_ ERROR,Trigger. STATE_ BLOCKED,Trigger. STATE_ NONE

// get the scheduler factory bean from the spring context
 Scheduler scheduler = (Scheduler)   getApplicationContext().getBean("schedulerfactorybean");
 // get the state 
 int state = scheduler.getTriggerState(triggerName,triggerGroup);
