Quartz：调度程序已关闭

Question

I have developed a small Java application in which i use the Quartz.jar library.

But when executing my application and calling Quartz, I get the following error message in my console:

org.quartz.SchedulerException: The Scheduler has been shutdown

I have no idea where it comes from and what causes the error.

Has anyone an idea what the solution to this could be?

Answer 1

If you don't edit the question to include the code for " executing my application and calling Quartz ", it's going to be really hard to tell exactly what could be happening.

However , it may have something to do with this little caveat about calling Scheduler.shutdown() :

Once you have shutdown a scheduler, it cannot be restarted

It might be that you are trying to start() a scheduler that was already shutdown, hence the error.

But once again, can't really tell if you don't include the related code.
