Jetty:以编程方式停止导致“1个线程无法停止”

标签: java jetty shutdown

我有一个嵌入式Jetty 6.1.26实例。 我希望通过发送到/shutdown的HTTP GET将其关闭。 所以我创建了一个JettyShutdownServlet

@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {

 resp.setStatus(202, "Shutting down.");
 resp.setContentType("text/plain");
 ServletOutputStream os = resp.getOutputStream();
 os.println("Shutting down.");
 os.close();
 resp.flushBuffer();

 // Stop the server.
 try {
    log.info("Shutting down the server...");
    server.stop();
 } catch (Exception ex) {
    log.error("Error when stopping Jetty server: "+ex.getMessage(), ex);
 }

但是,当我发送请求时,Jetty不会停止 - 一个帖子一直悬挂在org.mortbay.thread.QueuedThreadPool的{​​{1}}行上:

this.wait()

...

   // We are idle
   // wait for a dispatched job
   synchronized (this)
   {
       if (_job==null)
          this.wait(getMaxIdleTimeMs());
       job=_job;
       _job=null;
   }

它会阻塞一分钟,然后关闭。 我添加了Graceful shutdown,这应该允许我从servlet关闭服务器;但是,它从日志中看不到。

我已经这样解决了:

需要在Server server = new Server( PORT ); server.setGracefulShutdown( 3000 ); server.setStopAtShutdown(true); ... server.start(); if( server.getThreadPool() instanceof QueuedThreadPool ){ ((QueuedThreadPool) server.getThreadPool()).setMaxIdleTimeMs( 2000 ); } 之后调用

setMaxIdleTimeMs(),因为在start()中创建了threadPool。但是,线程已经创建并等待,因此它仅在所有线程至少使用一次后才适用。

除了中断所有主题或start()之类的可怕之外,我不知道还能做什么。

有什么想法吗?有好办法吗?
