Spring 4 Websocket和脚踩-控制器未达到

Question

我正在使用spring的官方示例（问候示例）：

http://spring.io/guides/gs/messaging-stomp-websocket/

一切似乎都正常，当我按连接时，我可以看到连接已建立，服务器已经连接好了。

但是，在连接后，当我向服务器提交“名称”时，我没有收到任何错误，也没有任何请求到达GreetingController。

我试图使日志级别处于跟踪状态，并且在执行“发送”时看到以下几行：

22 Ar 2014 17:10:52 DEBUG DispatcherServlet - Successfully completed request
22 Apr 2014 17:10:52 DEBUG ExceptionTranslationFilter - Chain processed normally

有任何想法吗？

PS，这是我使用的js代码的一部分（与网站相同）：

    function connect() {
        var socket = new SockJS('/MyWebApp/hello');
        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);
            });
        });
    }

    function disconnect() {
        stompClient.disconnect();
        setConnected(false);
        console.log("Disconnected");
    }

    function sendName() {
        debugger;
        var name = document.getElementById('name').value;
        stompClient.send("/app/hello", {}, JSON.stringify({ 'name': name }));
    }

Answer 1

好的，服务器正在捕获消息，但是它并没有执行任何操作，因此，我认为您应该：

1. 注意这一行“ config.setApplicationDestinationPrefixes（“ / app”）;“ 在WebSocketConfig类上;
2. 确保您的Controller带有@Controller，方法带有@MessageMapping（“ / hello”）;

Answer 2

好的，我有一个spring配置问题，我没有扫描必要的bean目录。
