        String[] reminderTime = getFirstReminderTime().trim().split(":");

            System.out.println("Job 1 Scheduled");

            Scheduler scheduler2 = new StdSchedulerFactory().getScheduler();
            scheduler2.start();
            scheduler2.scheduleJob(job, trigger2);
            System.out.println("Job 2 Scheduled");

        } catch (SchedulerException ex) {
            ex.printStackTrace();
        }
    }



    private void deleteJob()
    {
        try {
            Scheduler scheduler = new StdSchedulerFactory().getScheduler();
            scheduler.deleteJob(null);

        } catch (SchedulerException ex) {
            System.out.println(ex);
        }
    }
}

在这里，我创建了deleteJob()方法来删除并重新打开或重新安排passportReminder1()中列出的作业。但是我不知道怎么做。我可以删除或重新安排石英作业吗？我正在使用quartz 2 API。

Answer 1

我们可以通过两种方式做到：

手动杀死工作并重新开始
1. 使用以下代码：

scheduler.deleteJob（new JobKey（jobData.getJobName（）））;

有关详细信息，请参阅link。

你要做的是删除一个没用的新作业。

您可以像下面一样编辑您的deleteJob（）并在需要时调用它：

   private void deleteJob(Scheduler scheduler, String jobName)
    {
        try {

            scheduler.deleteJob(new JobKey(jobName));

        } catch (Exception ex) {
            System.out.println(ex);
        }
    }

如何删除或重新安排工作？
