SockJS无法创建/连接到Spring WebSocket

我正在学习Spring WebSocket。我已经成功运行了这个Spring WebSocket教程。现在我试图在我现有的Spring MVC应用程序中将按原样并入。当我从Chrome浏览器运行它时，我在其dev控制台中看到下面的错误。SockJS无法创建/连接到Spring WebSocket

Chrome的控制台

Opening Web Socket... 
GET http://localhost:8080/MyAppName/api/gs-guide-websocket/info?t=1497735312528 500 (Internal Server Error) -- abstract-xhr.js:132 
Whoops! Lost connection to http://localhost:8080/MyAppName/api/gs-guide-websocket -- stomp.min.js:8

服务器端错误

javax.servlet.ServletException: Could not resolve view with name '/MyAppName/api/gs-guide-websocket/info' in servlet with name 'MyAppName' 
at org.springframework.web.servlet.DispatcherServlet.render(DispatcherServlet.java:1262) 
at org.springframework.web.servlet.DispatcherServlet.processDispatchResult(DispatcherServlet.java:1037)

客户端

function connect() { 
    var socket = new SockJS('/MyAppName/api/gs-guide-websocket'); 
    stompClient = Stomp.over(socket); 
    stompClient.connect({}, function (frame) { 
     setConnected(true); 
     console.log('Connected: ' + frame); 
     stompClient.subscribe('/topic/greetings', function (greeting) { 
      showGreeting(JSON.parse(greeting.body).content); 
     }); 
    }); 
}

服务器端

@Configuration 
@EnableWebSocketMessageBroker 
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer { 

    @Override 
    public void configureMessageBroker(MessageBrokerRegistry config) { 
     config.enableSimpleBroker("/topic"); 
     config.setApplicationDestinationPrefixes("/app"); 
    } 

    @Override 
    public void registerStompEndpoints(StompEndpointRegistry registry) { 
     registry.addEndpoint("/MyAppName/api/gs-guide-websocket").withSockJS(); 
    } 

}

我试图解决现在这个为几个小时。我该如何解决这个问题？

你解决呢？我看到mt有同样的问题... – Juan

如果你的应用环境是MyAppName那么你并不需要在addEndpoint方法来指定它 - 这个路径是相对于你的aaplication上下文。

大概registry.addEndpoint("/MyAppName/api/gs-guide-websocket")注册与路径端点/MyAppName/MyAppName/api/gs-guide-websocket
