我开发了一个作业，我想每 5 分钟运行一次，但在某些情况下，作业完成时间可能会超过 5 分钟.

I have developed a job which I want to run say after every 5 mins, but there may be certain circumstances where the job completion time may exceeds 5 mins.

我正在使用石英调度程序使用 cron 表达式来安排我的工作.有什么办法可以告诉quartz scheduler 等待下一个作业运行，直到第一个作业完成?

I am using quartz scheduler to schedule my job using a cron expression. Is there any way to tell quartz scheduler to hold the next run of job untill first one is completed?

我正在寻找类似于 -

private static final ScheduledExecutorService executor = Executors.newScheduledThreadPool(1); executor.scheduledWithFixedDelay(..);

推荐答案

使用 有状态作业.来自文档:

不允许有状态的作业并发执行，这意味着新的触发之前发生的execute(xx) 方法完成会延迟.

stateful jobs are not allowed to execute concurrently, which means new triggers that occur before the completion of the execute(xx) method will be delayed.
