作业1 按计划每5分钟运行一次，大约需要1分钟才能完成.

Job 1 is scheduled to run every 5 minutes, and takes ~1 minute to complete.

大量工作堆积如山，工作1 需要15分钟才能运行.

A lot of work piles up and Job 1 takes 15 minutes to run.

现在有3个职位1 正在同时处理-我不希望这样.

如何防止作业1 再次添加到队列中?

There are now three Job 1's being processed concurrently - I don't want this.

---

How do I prevent Job 1 being added to the queue again if it is already there?

是否有Hangfire设置，还是需要手动轮询作业状态?

Is there Hangfire setting, or do I need to poll job statuses manually?

推荐答案

您可以使用

You can use DisableConcurrentExecution attribute to prevent multiple executions of a method concurrently. Just put this attribute above your method -

[DisableConcurrentExecution(timeoutInSeconds: 10 * 60)]
public void Job1()
{
    // Metohd body
}
