Websocket服务器到服务器的通信不起作用

Question

我有一个websocket服务器。我收到的消息是，收到消息后，我试图将其发送到另一个将实际处理这些消息的websocket服务器。我通过创建ClientEndpoint将消息发送到另一台服务器。我无法在客户端端点上得到任何响应。我不确定我的代码设置是否正确。请帮忙 ServerSocketHandler

public class ServerSocketHandler extends AbstractWebSocketHandler {
  private Map<WebSocketSession, ProcessingService> sessions = new HashMap<>();

  @Override
  public void afterConnectionEstablished(WebSocketSession session) throws Exception {
    sessions.put(session, new ProcessingService());
    log.info("New connection established from client, sessionId={}", session.getId());
  }

  @Override
  protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {
    sessions.get(session).send(message.getPayload());
  }

  @Override
  public void afterConnectionClosed(WebSocketSession session, CloseStatus status) throws Exception {
    sessions.get(session).close();
    sessions.remove(session);
  }

}

ProcessingService

@ClientEndpoint
public class ProcessingService {
  private Session session = null;
  private static final String SERVER_URL = "wss://serverb.com/endpoint";

  public ProcessingService() {
    try {
      WebSocketContainer container = ContainerProvider.getWebSocketContainer();
      this.session = container.connectToServer(this, URI.create(SERVER_URL));
    } catch (Exception e) {
      e.printStackTrace();
    }
  }

  @OnOpen
  public void onOpen(Session session) {
    this.session = session;
    log.info("New connection established to serverB, sessionId={}", session.getId());
  }

  @OnMessage
  public void onMessage(String message, Session session) {
    log.info(message);
  }

  @OnClose
  public void onClose(Session session, CloseReason reason) {
    this.session = null;
    log.info("connection closed, sessionId={}, code={}", session.getId(), reason.getCloseCode());
  }

  @OnError
  public void onError(Throwable t) {
    t.printStackTrace();
  }

  public void send(String message) throws Exception {
    this.session.getBasicRemote().sendText(message);
  }

  public void close() throws Exception {
    this.session.getAsyncRemote().sendBinary(ByteBuffer.wrap(new byte[0]));
  }
