如何使用Quartz在特定时区的特定时间执行一次作业

Question

我试图设置一个作业在一个用户使用Quartz的时区的特定时间的单一执行。现在，开箱即用，告诉调度器执行时区中的任何内容的唯一方法是通过cronschedule。对于Coors，我可能会将datetime转换为cron表达式，然后在第一次成功执行后立即停止触发器，但这有点难闻。

谢谢，

可以使用所需的时区更新现有触发器并重新安排作业：

http://quartz-scheduler.org/documentation/quartz-2.x/cookbook/updatetrigger

  // retrieve the trigger
  Trigger oldTrigger = sched.getTrigger(triggerKey("oldTrigger", "group1");

  // obtain a builder that would produce the trigger
  TriggerBuilder tb = oldTrigger.getTriggerBuilder();

  // update the schedule associated with the builder, and build the new trigger
  // (other builder methods could be called, to change the trigger in any desired way)

  Trigger newTrigger = tb.withSchedule(simpleSchedule()
 .withIntervalInSeconds(10)
 .withRepeatCount(10)
 .inTimeZone(TimeZone.getTimeZone("America/Los_Angeles"))
 .build();

 sched.rescheduleJob(oldTrigger.getKey(), newTrigger);
