我在專案中使用springmvc+mybatis開發一個實時重繪的專案，在本地測驗前端和后端都可以正常使用，在公司linux服務器上面發布測驗也能正常訪問。但在客戶服務器上部署運行訪問就報錯，由于是客戶的服務器，只能通過外網訪問。
前端報錯：
Firefox 無法建立到 ws://外網地址/專案名/websocket 服務器的連接。
Close mySocket finish ...
后臺日志，錯誤如下：

java中的代碼：
@RequestMapping("/websocket")
public class RTWebsocketController extends TextWebSocketHandler{
private ExecutorService executor = Executors.newCachedThreadPool();
@Autowired
private RTInfoService rtInfoService;
public String deviceCode = "";
@Autowired
private DeviceInfoService deviceInfoService;
private static final Logger logger = LoggerFactory.getLogger(RTWebsocketController.class);
@Override
protected void handleTextMessage(WebSocketSession session, TextMessage message) throws Exception {}
}
HandshakeInterceptor(握手類)
public class RTHandshakeInterceptor extends HttpSessionHandshakeInterceptor{
@Override
public void afterHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler,
Exception ex) {
super.afterHandshake(request, response, wsHandler, ex);
}
@Override
public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler arg 2,Map<String, Object> attributes) throws Exception {
if(request instanceof ServletServerHttpRequest){
ServletServerHttpRequest servletRequest = (ServletServerHttpRequest) request;
HttpSession session = servletRequest.getServletRequest().getSession(false);
if(session != null){
SystemUserInfo user = (SystemUserInfo) session.getAttribute("user");
attributes.put("user", user);
}
}
return true;
}
}

java的代碼沒有寫全，就貼了大概實作，具體的業務邏輯沒有貼出來。是在是不知道為什么原因，會的大神麻煩解答下，還有一個問題就是問什么tomcat9在本地部署也不能訪問。注：訪問地址有埠號，只是沒有貼上。
