使用ServerEndpoint获取客户端IP地址

Question

这意味着它将从本地网络上的许多用户那里获得连接。如何获得每个连接的IP地址？我用JSR356。

@ServerEndpoint(value = "/ws/example")
public class ExampleServlet {

     private static final AtomicInteger connectionIds = new AtomicInteger(0);
     private static final Set<ExampleServlet> connections = new CopyOnWriteArraySet<>();
     private Session session;

     @OnOpen
     public void start(Session session) {
         this.session = session;
         connections.add(this);
     }

     @OnClose
     public void end() {
     }

     @OnMessage
     public void incoming(String message) {
     }

     @OnError
     public void onError(Throwable t) throws Throwable {
     }
}

Answer 1

不幸的是，JSR356 Websocket规范没有公开客户端IP地址。解决方案，如何破解，我在那里找到了：JSR-356 WebSockets with Tomcat - How to limit connections within single IP address?

Answer 2

这是针对websocket的，spring @重写公共afterConnectionEstablished(WebSocketSession会话)抛出异常{WebSocketSession。

 }
