我正在使用实现 ServletContextListener 的 servlet 来启动石英调度程序实例@starup。在 contextDestroyed() 方法中，调度程序实例被停止。

@Override
public void contextDestroyed(ServletContextEvent sce) {
    try {
        Scheduler scheduler = QuartzSchedulerUtil.getCurrentScheduler();
        scheduler.shutdown(true);
        // Sleep for a bit so that we don't get any errors
        Thread.sleep(1000);
        Driver mySqlDriver = DriverManager.getDriver(hibernateConnectionUrl);
        DriverManager.deregisterDriver(mySqlDriver);
    } catch (SchedulerException ex) {
        Logger.getLogger(QuartzServlet.class.getName()).log(Level.SEVERE, null, ex);
    } catch (InterruptedException ex) {
        Logger.getLogger(QuartzServlet.class.getName()).log(Level.SEVERE, null, ex);
    } catch (SQLException ex) {
        Logger.getLogger(QuartzServlet.class.getName()).log(Level.SEVERE, null, ex);
    }        
    System.out.println("THE QUARTZ APP STOPPED");
}

但是当应用程序被部署时，我收到内存泄漏警告，指出woker 线程没有停止。

appears to have started a thread named [Timer-0] but has failed to

我尝试了帖子中提到的解决方案 - http://forums.terracotta.org/forums/posts/list/15/4341.page 但是在取消部署应用程序时仍然收到严重的内存泄漏警告。

org.quartz.scheduler.interruptJobsOnShutdown 如果您想关闭作业仍在执行中，您可以设置该属性以中断作业。
