How to run multiple jobs in Quartz ?

In Quartz scheduler framework, each job will be attached to an unique trigger and run it by scheduler.

1. Create 3 Quartz’s jobs

public class Job1 implements Job { 

   @Override

   public void execute(JobExecutionContext context) throws JobExecutionException {

      System.out.println("Job 1 is runing");

   }

}

public class Job2 implements Job {

   @Override

   public void execute(JobExecutionContext context) throws JobExecutionException {

      System.out.println("Job 2 is runing");

   }

}

public class Job3 implements Job {

   @Override

   public void execute(JobExecutionContext context) throws JobExecutionException {

      System.out.println("Job 3 is runing");

   } 

}

2. Declare above 3 jobs, assign to 3 particular triggers and schedule it

JobKey jobKey1 = new JobKey("job1", "group1");

JobDetail job1 = JobBuilder.newJob(Job1.class).withIdentity(jobKey1).build();

JobKey jobKey2 = new JobKey("job2", "group1");

JobDetail job2 = JobBuilder.newJob(Job2.class).withIdentity(jobKey2).build();

JobKey jobKey3 = new JobKey("job3", "group1");

JobDetail job3 = JobBuilder.newJob(Job3.class).withIdentity(jobKey3).build();

Trigger trigger1 = TriggerBuilder.newTrigger().withIdentity("myTriggerName1", "group1")

    .withSchedule(CronScheduleBuilder.cronSchedule("0/5 * * * * ?")).build();

Trigger trigger2 = TriggerBuilder.newTrigger().withIdentity("myTriggerName2", "group1")

    .withSchedule(CronScheduleBuilder.cronSchedule("0/5 * * * * ?")).build();

Trigger trigger3 = TriggerBuilder.newTrigger().withIdentity("myTriggerName3", "group1")

    .withSchedule(CronScheduleBuilder.cronSchedule("0/5 * * * * ?")).build();

Scheduler scheduler = new StdSchedulerFactory().getScheduler();

scheduler.start();

scheduler.scheduleJob(job1, trigger1);

scheduler.scheduleJob(job2, trigger2);

scheduler.scheduleJob(job3, trigger3);
