How to reschedule the job execution interval in Quartz?

Question

I am a bit new to Quartz. Is there a way to update the job execution interval for an already submitted Quartz job? Does this interval get updated immediately? Do you have to

Answer 1

Perhaps there is a static method triggerKey() somewhere in the Quartz library. However, I managed to reschedule an existing Quartz job (using Quartz 2.3.2) without using this (potential) method, but rather using the TriggerKey class as follows:

    boolean updateExisting = true; // try it also with false
    int aveId = 1234; // change it as you wish
    java.util.Date closeDate = new java.util.Date(); // change it as you wish

    SchedulerFactory sf = new StdSchedulerFactory("... /quartz_priority.properties");
    Scheduler scheduler = sf.getScheduler();

    TriggerKey triggerKey = new TriggerKey("trigger" + aveId, "group1");

    if (updateExisting) {
        Trigger oldTrigger = scheduler.getTrigger(triggerKey);
        TriggerBuilder oldTriggerBuilder = oldTrigger.getTriggerBuilder();

        Trigger newTrigger = oldTriggerBuilder.startAt(closeDate).build();
        scheduler.rescheduleJob(triggerKey, newTrigger);

    } else {
        Trigger trigger = TriggerBuilder.newTrigger().withIdentity(triggerKey).startAt(closeDate).build();

        // Define job instance
        JobDetail job1 = JobBuilder.newJob(.class).withIdentity("job" + aveId, "group1").build();

        JobDataMap map = job1.getJobDataMap();
        map.put(, aveId);

        // Schedule the job with the trigger
        scheduler.scheduleJob(job1, trigger);
    }
