Quartz: Scheduler: Get Scheduler Name

'org.quartz.Scheduler' interface provides 'getSchedulerName' method, it is used to get the name of the scheduler.

Find the below working example.

HelloJob.java

package com.sample.jobs;

import org.quartz.Job;
import org.quartz.JobExecutionContext;
import org.quartz.JobExecutionException;
import org.quartz.SchedulerException;

public class HelloJob implements Job {
 public void execute(JobExecutionContext jec) throws JobExecutionException {
  String schedulerName = null;
  
  try {
   schedulerName = jec.getScheduler().getSchedulerName();
  } catch (SchedulerException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
  
  System.out.println("Hello!!!");
  System.out.println("Job is triggered by scheduler : " + schedulerName);
 }
}

QuartzSchedulerEx.java

package com.sample.app;

import java.util.Date;

import org.quartz.Scheduler;
import org.quartz.SchedulerException;
import org.quartz.SchedulerFactory;
import org.quartz.impl.JobDetailImpl;
import org.quartz.impl.StdSchedulerFactory;
import org.quartz.impl.triggers.SimpleTriggerImpl;

import com.sample.jobs.HelloJob;

public class QuartzSchedulerEx {
 public static void main(String args[]) throws SchedulerException, InterruptedException {

  // Initiate a Schedule Factory
  SchedulerFactory schedulerFactory = new StdSchedulerFactory();

  // Retrieve a scheduler from schedule factory
  Scheduler scheduler = schedulerFactory.getScheduler();

  // Start scheduler
  scheduler.start();

  JobDetailImpl helloJobDetails = new JobDetailImpl();
  helloJobDetails.setName("Hello Job");
  helloJobDetails.setJobClass(HelloJob.class);

  // Creating schedule time with trigger
  SimpleTriggerImpl trigger1 = new SimpleTriggerImpl();
  trigger1.setStartTime(new Date(System.currentTimeMillis() + 500));
  trigger1.setRepeatCount(-1);
  trigger1.setRepeatInterval(1000);
  trigger1.setName("First Trigger");
  trigger1.setPriority(10); // Setting trigger 1 priority to 10

  scheduler.scheduleJob(helloJobDetails, trigger1);
 }
}

Output

Hello!!!

Job is triggered by scheduler : DefaultQuartzScheduler

Hello!!!

Job is triggered by scheduler : DefaultQuartzScheduler
