当我使用Quartz 2.x运行我的Web应用程序时收到此消息。它运行正常但我在说服务器
时遇到此错误INFO: Server startup in 1792 ms

GRAVE: The web application [/servlet] appears to have started a thread named [Thread-4] but has failed to stop it. This is very likely to create a memory leak.

这可能是由于在Tomcat关闭或Web应用程序重新部署时没有关闭Quartz调度程序（很可能是您的情况）。
您需要实现一个ServletContextListener，并在其contextDestroyed方法中需要执行此操作：
scheduler.shutdown( true ); // true = wait for jobs to complete
// you may want to give Quartz some extra time to shutdown
//Thread.sleep(1000);
您可能还希望配置Quartz线程池以将其线程标记为＆＃34;守护程序线程＆＃34; （org.quartz.threadPool.makeThreadsDaemons = true）因为它们不会阻止JVM停止。否则，JVM将等待所有这些工作线程完成。
