我在 STOMP Java 客户端(Spring 项目)中开发了我的 websocket 客户端，并在 Spring 启动中实现了服务器。
当客户端/服务器握手发生时，我遇到了连接升级问题。
Java客户端代码
List transports = new ArrayList<>(1);
transports.add(new WebSocketTransport(new StandardWebSocketClient()));
SockJsClient sockjsClient = new SockJsClient(transports);
WebSocketStompClient stompClient = new WebSocketStompClient(sockjsClient);
stompClient.setMessageConverter(new MappingJackson2MessageConverter());
stompClient.setTaskScheduler(new ConcurrentTaskScheduler());
StompSessionHandler sessionHandler = new SessionHandler();
stompClient.connect("ws://localhost:9090/health", sessionHandler);
服务器端
@Override
public void registerStompEndpoints(StompEndpointRegistry stompEndpointRegistry) {
stompEndpointRegistry.addEndpoint("/health")
.setAllowedOrigins("*")
.withSockJS();
}
@Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.enableSimpleBroker("/topic");
registry.setApplicationDestinationPrefixes("/app");
}
连接到服务器时在客户端生成的异常

在 tomcat localhost_access_log 中，我看到以下请求信息
127.0.0.1 - - [01/Nov/2018:22:09:41 +0530] "GET /health/info HTTP/1.1" 302 - 0
127.0.0.1 - - [01/Nov/2018:22:09:41 +0530] "GET /login.jsp HTTP/1.1" 200 7649 16

127.0.0.1 - - [01/Nov/2018:22:09:41 +0530] "GET /login.jsp HTTP/1.1" 200 7649 0
我没有找到有关如何解决此问题及其原因的任何信息。
请帮我解决这个问题。
