使用ServerEndpoint時獲取客戶端IP地址

Question

意味着它將從本地Web中的許多用戶獲得連接。我怎樣才能得到每個單一連接的IP地址？我使用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 { 
    } 
}

不幸的是，JSR356 Websocket規範不公開客戶端IP地址。解決方案，如何破解這個，我發現在那裏：JSR-356 WebSockets with Tomcat - How to limit connections within single IP address?

這對於WebSocket的彈簧 @覆蓋 公共無效afterConnectionEstablished（WebSocketSession會話）拋出異常{ 的System.out.println（ 「connectionestablished！」 + session.getLocalAddress（））;
}
