即使删除了 Quartz 作业，它们仍然会出现。你知道为什么吗？

Question

我看到调度程序返回相同的作业 (scheduler.getCurrentlyExecutingJobs())，即使在删除它之后 (scheduler.deleteJob(jobExCntxt.getJobDetail().getName(), jobExCntxt.getJobDetail().getGroup()))。我做的事正确吗？我想永远删除该作业和相关线程。这可能吗？

        try {
            List<JobExecutionContext> jobExCntxts = scheduler.getCurrentlyExecutingJobs();
            if(jobExCntxts != null){

                for(JobExecutionContext jobExCntxt: jobExCntxts){
                    if(jobExCntxt != null){
                        Date triggerTime =  DateUtils.addMinutes(jobExCntxt.getTrigger().getPreviousFireTime(), 1);
                        if(triggerTime.before(Calendar.getInstance().getTime())){
                            System.out.println("Deleting a long living job !");

                            System.out.println("Delete return = " + scheduler.deleteJob(jobExCntxt.getJobDetail().getName(), 
                                        jobExCntxt.getJobDetail().getGroup()));
                        }
                    }
                }
            }

        } catch (SchedulerException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }

您是否尝试过中断（）工作？ deleteJob() 仅从作业存储中删除作业。
