javascript - 未调用 Spring Stomp Websockets 回调

Question

给定一个 websocket 配置:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfiguration extends AbstractWebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry registry) {
        registry.setApplicationDestinationPrefixes("/app");
        registry.enableSimpleBroker("/queue", "/topic");
    }

    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/add").withSockJS();
    }
}

和客户端javascript:

<script type="text/javascript">
    console.log('begin javascript');

    var stompClient = null;

    function connect() {
        var socket = new SockJS('/myapp/add');
        stompClient = Stomp.over(socket);
        stompClient.connect({}, function(frame) {
            console.log('Connected to STOMP: ' + frame);
            stompClient.subscribe('/user/topic/abc', function(calResult) {
                console.log('*** Got it ***');
            });
        });
    }

    connect();

</script>

并从服务器发送此消息:

messagingTemplate.convertAndSendToUser(username, "/topic/abc", "hello");

回调永远不会被触发。

javascript 控制台显示连接已建立:

Connected to STOMP: CONNECTED user-name:jschmoe heart-beat:0,0 version:1.1 SUBSCRIBE id:sub-0 destination:/user/topic/abc

并且 tomcat 控制台显示:

Processing SUBSCRIBE destination=/topic/abc-useryl3ovhr2 subscriptionId=sub-0 session=yl3ovhr2 user=jschmoe payload=byte[0]

然后在发送消息时:

Processing MESSAGE destination=/topic/abc-useryl3ovhr2 session=null payload=hello

似乎除了回调之外一切正常。

在我的例子中，问题是由 XML 配置引起的，一旦我切换到带有 @EnableWebSocketMessageBroker 注释的 Java 配置，我就在客户端收到了消息。
