quartz quartz中的pauseJob()和pauseTrigger()有什么区别？如何选择其中一个使用？现在我想暂停/干预一个特定的工作我该怎么办

我的调度程序代码如下

JobDetail job = new JobDetail();
            job.setName("pollerjob"+pollerId);
            job.setJobClass(Pollersheduller.class);
            job.getJobDataMap().put("socialMediaObj", socialMediaObj);
            job.getJobDataMap().put("queue", queue);


            //configure the scheduler time
            SimpleTrigger trigger = new SimpleTrigger();
            trigger.setName("pollerSocial"+pollerId);
            trigger.setStartTime(new Date(System.currentTimeMillis() + 1000));
            trigger.setRepeatCount(SimpleTrigger.REPEAT_INDEFINITELY);
            trigger.setRepeatInterval(Long.parseLong(intervel));


            //schedule it
            Scheduler scheduler = null;
            try {
                scheduler = new StdSchedulerFactory().getScheduler();
                scheduler.start();
                scheduler.scheduleJob(job, trigger);
            } catch (SchedulerException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
