Controller component issue with Spring and SockJs - spring

Question

I have a problem with a configuration of a WebSocket using Spring and SockJs.
I have configured all my app like Spring Documentation, the connection seems to be fine, but when I send a message the Controller is never involved and it doesn't work.
This is the Configuration component:
#Configuration
#EnableWebMvc
#EnableWebSocketMessageBroker
public class MyWebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer implements WebSocketConfigurer {
#Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
registry.addEndpoint("/mySocket").withSockJS().setInterceptors(new MySocketHandshakeInterceptor());;
}
#Override
public void configureMessageBroker(MessageBrokerRegistry registry) {
registry.setApplicationDestinationPrefixes("/app").enableSimpleBroker("/topic");
}
#Override
public void registerWebSocketHandlers(WebSocketHandlerRegistry registry) {
}
}
This is the HandshakeInterceptor implementation:
public class MySocketHandshakeInterceptor implements HandshakeInterceptor {
#Override
public void afterHandshake(ServerHttpRequest paramServerHttpRequest, ServerHttpResponse paramServerHttpResponse, WebSocketHandler paramWebSocketHandler, Exception paramException) {
// TODO Auto-generated method stub
System.out.println("MySocketHandshakeInterceptor afterHandshake");
}
#Override
public boolean beforeHandshake(ServerHttpRequest request, ServerHttpResponse response, WebSocketHandler wsHandler, Map<String, Object> paramMap)
throws Exception {
System.out.println("MySocketHandshakeInterceptor beforeHandshake");
return true;
}
}
This is the Controller component:
#Controller
public class MySocketController {
#MessageMapping("/testsocket")
#SendTo("/topic/testresponse")
public MessageOut test(MessageIn message) throws Exception {
System.out.println("MySocketController start");
System.out.println("MySocketController test "+ message);
return new MessageOut("test OK");
}
}
These are MessageIn and MessageOut:
public class MessageIn {
private String test;
/**
* #return the test
*/
public String getTest() {
return test;
}
}
public class MessageOut {
private String result;
public MessageOut(String result) {
super();
this.result = result;
}
/**
* #return the test
*/
public String getResult() {
return result;
}
/**
* #param result the result to set
*/
public void setResult(String result) {
this.result = result;
}
}
Finally, this is the client side (javascript):
var socketSession = {};
connectToMySocket();
function connectToVideoSocket() {
socketSession.socket = new SockJS("/mySocket");
socketSession.socket.stomp = Stomp.over(socketSession.socket);
socketSession.socket.stomp.debug = null;
socketSession.socket.stomp.connect({}, function () {
socketSession.socket.stomp.subscribe("/topic/testresponse", function (data) {
console.log(data);
});
});
}
This is the command that I launch to test the socket:
socketSession.socket.stomp.send("app/testsocket", {}, JSON.stringify({'test': 'test'}));
In the system out console I can only see the two rows:
MySocketHandshakeInterceptor beforeHandshake
MySocketHandshakeInterceptor afterHandshake
The interceptor works fine, but I don't see any print by the Controller component.
What's wrong?
Thanks.

I resolved by myself.
It was a problem of the client-side.
The correct script is:
var mySocket = undefined;
var stompClient = undefined;
connectToVideoSocket();
function connectToVideoSocket() {
mySocket = new SockJS('/mySocket');
stompClient = Stomp.over(mySocket);
stompClient.debug = null;
stompClient.connect({}, function(frame) {
stompClient.subscribe('/topic/testresponse', function(data){
console.log(JSON.parse(data.body).result);
});
});
}
In this way it works fine.
