java - Jetty Websocket 空闲超时

Question

我最近一直在使用 Jetty API(9.4.5 版本) 研究带注释的 websockets，并与之交谈。

但是我遇到了一个问题，5 分钟后(我相信这是默认计时器)， session 关闭(这不是由于错误)。 我找到的唯一解决方案是在关闭事件时通知我的套接字并在新套接字中重新打开连接。

但是我在 stackOverflow 上读到，通过在 WebsocketPolicy 中设置 IdleTimeOut，我可以避免这个问题:

1. 例如，我尝试设置为 3600000，但行为根本没有改变

2. 我也尝试将其设置为 -1 但出现以下错误:IdleTimeout [-1] 必须大于或等于 0

   private ServletContextHandler setupWebsocketContext() {
       ServletContextHandler websocketContext = new AmosContextHandler(ServletContextHandler.SESSIONS |  ServletContextHandler.SECURITY);
   
       WebSocketHandler socketCreator = new WebSocketHandler(){
           @Override
           public void  configure(WebSocketServletFactory factory){    
               factory.getPolicy().setIdleTimeout(-1);
               factory.getPolicy().setMaxTextMessageBufferSize(MAX_MESSAGE_SIZE);
               factory.getPolicy().setMaxBinaryMessageBufferSize(MAX_MESSAGE_SIZE);
               factory.getPolicy().setMaxTextMessageSize(MAX_MESSAGE_SIZE);
               factory.getPolicy().setMaxBinaryMessageSize(MAX_MESSAGE_SIZE);          
               factory.setCreator(new UpgradedSocketCreator());
   
   
           }
   
       };  
       ServletHolder sh = new ServletHolder(new WebsocketChatServlet());  
       websocketContext.addServlet(sh, "/*");  
       websocketContext.setContextPath("/Chat");
       websocketContext.setHandler(socketCreator);
       websocketContext.getSessionHandler().setMaxInactiveInterval(0);
       return websocketContext;
   }
   

我还尝试通过调用 session.getpolicy.setIdleTimeOut() 直接在 OnConnect 事件中更改策略，但我没有注意到任何结果。

这是预期的行为还是我遗漏了什么？感谢您的帮助。

注释的 WebSockets 在注释中有自己的超时设置。

@WebSocket(maxIdleTime=30000)
