Quartz Scheduler for java- How to run job every 5 minutes

Question

Friends, I am using quartz scheduler for running a task every 5 minutes starting when application deployed & running continuously so i have written code as:

SchedulerFactory sf = new StdSchedulerFactory();
Scheduler sche = sf.getScheduler();

JobDetail job = newJob(RomeJob.class).withIdentity("Id1", "Rome").build();
CronTrigger trigger = newTrigger().withIdentity("Id1Trigger", "Rome").withSchedule(cronSchedule("0 0/5 * * * ?"))
.build();
sche.scheduleJob(job, trigger);
sche.start();

But its working sometime sometimes not. Please tell me whether i am missing something here?

Solution 1

You have many ways one of them is use trigger builder something like

trigger = newTrigger()
    .withIdentity("mytrigger", "group1")
    .startNow()
    .withSchedule(simpleSchedule()
            .withIntervalInMinutes(5)
            .repeatForever())
    .build();

Solution 2

Do not use Cron schedule but simple schedule instead:

Trigger trigger = newTrigger().
  withIdentity("Id1Trigger", "Rome").
  withSchedule(
    simpleSchedule().
      withIntervalInMinutes(5).
      repeatForever()
  ).build();

+1 since the OP asked for "every 5 minutes starting when application deployed", not every 5 minutes on the wallclock.
