使用石英调度程序时，如何处理JavaFX应用程序的应用程序关闭？

Question

So I want to write a JavaFX app that will have some background tasks using Quartz Scheduler http://www.quartz-scheduler.org/documentation/quartz-2.2.x/quick-start.html#quartz-quick-start-guide

Based on their documentation you should call shutdown() at the end.

How/when/where is the right place to call shutdown() in a JavaFX app so that if the users closes the window or does something that exists the app this function will be called.

Answer 1

There are 2 places where you could call the shutdown() method.

First is the stop() method you can override in your Application class. This will be called when your application shuts down. From experiance though, that is not always the case unfortunatly.

So the second one might be a better solution. Wich is setting the onCloseRequest eventHandler on the stage retrieved from the start() method in your Application class. Mainly that eventHandler is used to prevent a application from shutingdown (cause of various reasons like unsaved changes etc.), besides it is a failproof way to add a shutdown hook. (like you need)
