Websocket 块在客户端插头拔出/断电时不会超时

【中文标题】Websocket 块在客户端插头拔出/断电时不会超时

【问题描述】：

我的 Tomcat + Spring websocket 应用程序有一个奇怪的问题。当用户在没有发送“关闭”信号的情况下断开连接时，由于断电或拔插头，线程将在大约 10 秒后阻塞。

这个函数的线程阻塞：

org.springframework.web.socket.WebSocketSession.sendMessage(WebSocketMessage<?> wsm) throws IOException;

我尝试在我的 AppConfig 中添加一条线以尝试设置 3 秒的超时，但它似乎无法正常工作，因为 块似乎持续了 15 分钟以上，然后才抛出异常。

@Bean(name="servletServerContainerFactoryBean")
public int maxSessionIdleTimeout() 
  return 3000;

这是 eventual SocketTimeoutException 之后的堆栈跟踪

Step: 2304
SendB -> test isOpen -> sendMes -> Done -> Finished Send.
SendB -> test2 isOpen -> sendMes -> User closed connection during packet sending: s01
Propogating exception up!

一次阻塞线程 15 分钟是一个主要问题。任何有关为什么会发生这种情况以及如何解决它的信息将不胜感激。谢谢！

终于找到答案了。这实际上是一个系统设置。
