Java Springboot 2.2.11 websocket连接问题

在我将SpringBoot从2.2.10更新到2.2.11之后，如果我尝试连接我的客户机，我总是会收到ConnectionLostException

以下是我的测试课程的一部分：

    @BeforeEach()
    public void setup() throws InterruptedException, ExecutionException, TimeoutException {
      URL = "ws://localhost:" + port + "/notifications";
      WebSocketStompClient stompClient = new WebSocketStompClient(new 
      SockJsClient(createTransportClient()));
      stompClient.setMessageConverter(new SimpleMessageConverter());

      stompSession = stompClient.connect(URL, new StompSessionHandlerAdapter() {
      }).get(3, SECONDS);
   }

这是堆栈跟踪：

同样，我唯一改变的是将spring boot更新为2.2.11版。 我没有发现在SpringBoot2.2.11中websocket处理发生了变化

编辑： 如果我运行angular web应用程序，我会在控制台中收到以下消息：

到“ws://localhost:4200/sockjs node/589/savha4qo/WebSocket”的WebSocket连接失败：WebSocket在建立连接之前已关闭

编辑2： 状态代码是1002

编辑3：

问题是，我还使用了SpringCloudStarterSleuth中的org.springframework.cloud。如果我把它取下来，一切正常。但是我也需要它。

试着从项目依赖项中排除不必要的lib，正如您在编辑中提到的那样，它将起作用。对于mvn或gradle
