quartzScheduler_Worker-1] but has failed to stop it. This is very likely to create a memory leak解决

出现此问题是由一于spring 启动了quartz，而当tomcat 关闭的时候而没有关闭造成的。

在web 加一个监听器当关系的时候判断作业是否启动，启动就关闭。

<!-- 作业监听器 -->
 <listener>
   <listener-class>cn.test.job.JobListener</listener-class>
 </listener>

 

 

public class JobListener implements ServletContextListener {

 public void contextDestroyed(ServletContextEvent arg0) {
  Scheduler job = (Scheduler) SpringBeanLoader.getSpringBean("quartzScheduler");
  try {
   if(job.isStarted()){
    job.shutdown();
    Thread.sleep(1000);
   }
  } catch (SchedulerException e) {
   e.printStackTrace();
  } catch (InterruptedException e) {
   e.printStackTrace();
  }

 }

 public void contextInitialized(ServletContextEvent arg0) {
  

 }

 加 上过后会有此显示，创建的10个线程就会被关闭。如果Thread.sleep(1000)如果不会有些线程不会关闭。不知道有什么更好方法不。

加上过后再停止tomcat 就会显示相应线程就会关闭。
