使用 StompClient 在 Spring WebSocket 上传递消息时出错

Question

我正在尝试向我的主题发送消息，但问题是当我发送消息时没有任何反应...我使用的是 apache tomcat 7.0.53

代码：

@Service
public class ExampleServiceImpl implements ApplicationListener<BrokerAvailabilityEvent> {

private AtomicBoolean brokerAvailable = new AtomicBoolean();

@Autowired
private MessageSendingOperations<String> messagingTemplate;

@Override
public void onApplicationEvent(BrokerAvailabilityEvent event) {
    this.brokerAvailable.set(event.isBrokerAvailable());
}

@Scheduled(fixedDelay=3000)
public void testing() {
    if (this.brokerAvailable.get()) {
        this.messagingTemplate.convertAndSend("/topic/greetings", "Testing....");
    }
}

Javascript 连接：

        var socket = new SockJS('/kupo/application'); // <!-- My endpoint
        var stompClient = Stomp.over(socket);
        stompClient.connect({}, function(frame) {
            
            var username = frame.headers['user-name'];
            console.log("User connected: " + username);
            
            stompClient.subscribe("/topic/greetings", function(message) { // <-- Topic where I want to received the message
                console.log("TOPIC:",message);
            });
            
        } , function(error) {
            console.log("STOMP protocol error " + error);
        });

浏览器控制台：

Opening Web Socket... stomp.min.js:8
Web Socket Opened... stomp.min.js:8
>>> CONNECT
accept-version:1.1,1.0
heart-beat:10000,10000

<<< CONNECTED
user-name:balbi
heart-beat:0,0
version:1.1

connected to server undefined stomp.min.js:8
User connected: balbi 
>>> SUBSCRIBE
id:sub-0
destination:/topic/greetings

Websocket 上下文配置：

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketApplicationContext extends AbstractWebSocketMessageBrokerConfigurer {

@Autowired
private Environment env;

@Override
public void registerStompEndpoints(StompEndpointRegistry registry) {
    if (env.acceptsProfiles("test.tomcat")) {
        registry.addEndpoint("/application")
                .setHandshakeHandler(
                        new DefaultHandshakeHandler(new TomcatRequestUpgradeStrategy()))
                .withSockJS();
    } else {
        registry.addEndpoint("/application").withSockJS();
    }
}

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

连接到您的应用程序时，我设法从 JavaScript 控制台向主题发送了一条消息，并在网页中返回一条消息。

var socket = new SockJS('/kupo/application');
var stompClient = Stomp.over(socket);
stompClient.send('/topic/greetings',{},"hello");

我收到了：

<<< MESSAGE
subscription:sub-0
content-length:5
message-id:ts3oov6b-1
destination:/topic/greetings
content-length:5

hello 

您的调度任务是否按预期调用？

为什么你在你的主要配置中是importing some Configurations and still scanning the configuration package？不应该是其中之一吗？
