quartz-scheduler - Quartz Scheduler 工作线程问题

Question

我对 Quartz Scheduler 工作线程有疑问。我创建了一个调度程序任务，它将每 3 小时执行一次。我创建了一份工作和一个触发器。当我执行这个调度程序时，我观察到一个奇怪的行为，同一个作业被分配给 10 个工作线程。这 10 个工作线程正在执行相同的代码 10 次。我该如何解决这个问题...？

谁能帮我解决这个问题。我是 Quartz Scheduler 的新手。

提前致谢，阿马尔

来自quartz manual在 org.quartz.threadPool.threadCount header 下

If you only have a few jobs that fire a few times a day, then 1 thread is plenty! If you have tens of thousands of jobs, with many firing every minute, then you probably want a thread count more like 50 or 100 (this highly depends on the nature of the work that your jobs perform, and your systems resources!).

这就是可以更改 threadCount 的方式。
