如何获取注册到 Quartz 调度器的触发器列表

Question

I need to build a gui showing some kind of 'job queue'.

I create triggers dynamically and schedule them with jobScheduler.scheduleJob(trigger); . I pass also some data via the trigger's dataMap.

How can I get back the list of triggers which didn't yet fire?

I found a way to get the currently running jobs, but no way to get the list of registered trigger.

Should I maintain this list by myself and remove stuff when it finished executing by implementing a trigger listener?

Can I get the underlying JobStore and invoke getTriggerNames() or similar? But how can I get the JobStore. All I have is a Scheduler instance (actualy a StdScheduler), and there seems no way to get a JobStore instance from it.

(I use spring to get the Scheduler from a SchedulerFactoryBean)

Answer 1

Ok, I'm just tired.

There is a method getTriggerNames() in the Scheduler. So it solves my problem.

Answer 2

With modern Quartz (and a bit of unnecessary Spring DSL) if you don't know job or group name:

@Autowired
private Scheduler scheduler;

public void x() {
    scheduler.getTriggerKeys(GroupMatcher.anyGroup()).stream()...;
    // like
    scheduler.getTriggerKeys(GroupMatcher.anyGroup()).stream()
            .filter(__ -> {
                try {
                    return "YYY".equals(scheduler.getTrigger(__)
                            .getJobDataMap().getString("myParam"));
                } catch (SchedulerException e) { return false; }
            });
    // or like
    scheduler.getTriggerKeys(GroupMatcher.anyGroup()).stream()
            .filter(__ -> "YYY".equals(__.getName()));
}
