How to Schedule a Job in Java in 3 easy steps.

How to Schedule a Job just like CronJob (in Java) in 3 easy steps ?

1)     Include Quartz dependency in pom.xml

<dependency>

           <groupId>opensymphony</groupId>

           <artifactId>quartz</artifactId>

           <version>1.6.3</version>

</dependency>

2)     Create a Job which needs to be run after fixed interval

import org.quartz.Job;

import org.quartz.JobExecutionContext;

public class TesttJob implements Job {

public void execute(JobExecutionContext context) {

System.out.println("Test Job running successfully");

}

}

3)     Create a CronTrigger which creates job object, trigger object and schedule it at the fixed interval.

public class CrontTriggerJob {

private static JobDetail testJob = null;

private static CronTrigger testTrigger = null;

    

public static void main(String[] args) throws ParseException, SchedulerException {

testJob = new JobDetail("dummyJobName","quartzJobGroup",TesttJob.class);

// Run after every 5 minutes        

testTrigger= new  CronTrigger("dummyCrontName","quartzJobGroup","0/5 * *   * * ?");

          

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

scheduler.start();

scheduler.scheduleJob(testJob, testTrigger);

}

}
