我的错误显示在浏览器的控制台中：

"WebSocket connection to 'ws://localhost:32768/DspClusterWebServices/myHandler' failed: Unexpected response code: 200"

我正在使用Spring Websockets 4.1.5和Tomcat 8.0.18。我的WebSocketConfigurer实现类如下所示：

@Configuration
@Controller
@EnableWebSocket
public class WebSocketConfig implements WebSocketConfigurer
{
   class MyHandler implements WebSocketHandler
   {
      @Override
      public void afterConnectionEstablished(WebSocketSession session) throws Exception
      {
         System.out.println("afterConntectionEstablished called");
      }

       ...implements rest of functions with a System.out.println and false for supportsPartialMessages()

      }
   }

   @Override registerWebSocketHandlers(WebSocketHandlerRegistry registry)
   {
      registry.addHandler(myHandler(), "myHandler").withSockJS();
   }

   @Bean
   public WebSocketHandler myHandler()
   {
      return new MyHandler();
   }
}

我的testWebsocketClient.js尝试与此代码连接，但错误代码为200：

websocket = new WebSocket("ws://localhost:8080/myApp/myHandler");

我不知道下一步该怎么做。我以为这会导致afterConnectionFounded（WebSocketSession
session）方法启动？代码200不好吗？
