石英:内存泄漏？

Question

我每小时都在使用Quartz来完成一项工作.servlet在Tomcat上运行,我正在使用ServletConextListener监听上下文被销毁的时间.

当我关闭tomcat时,我收到消息:

"似乎已经启动了一个名为[MyScheduler_Worker-1]但未能阻止它的线程".

但后来我看到这个消息:

"[DEBUG] 28 Sep 11:45:26.671 AM MyScheduler_Worker-1 [org.quartz.simpl.SimpleThreadPool]

WorkerThread被关闭."

因此可以安全地假设因为这个线程没有内存泄漏？

这是我的日志的样子:

{SEVERE: The web application [/*************] appears to have started a thread

named [MyScheduler_Worker-1] but has failed to stop it. This is very likely to c

reate a memory leak.

您可以假设没有内存泄漏，因为您看到线程关闭消息。但是，可以通过在关闭之前清除线程来克服警告。

The shutdown-hook plugin catches the event of the JVM terminating, and calls shutdown on the scheduler.
