WebSocketAnnotationMethodMessageHandler没有匹配方法

Question

我正在使用Stomp编写WebSocket客户端，当我使用Stomp客户端发送请求时，日志输出为:

15:17:44.688]-[clientInboundChannel-59]-[org.springframework.web.socket.messaging.WebSocketAnnotationMethodMessageHandler]-{Searching methods to handle SEND /app/vehicle session=qnlerizz}
15:17:44.688]-[clientInboundChannel-59]-[org.springframework.web.socket.messaging.WebSocketAnnotationMethodMessageHandler]-{No matching methods.}

表示客户端没有问题。服务器找不到匹配的URL来处理请求。但我已经有了一个处理方法。这是代码:

@Controller
@Log4j2
public class WebSocketController {
    public SimpMessagingTemplate template;
    @Autowired
    public WebSocketController(SimpMessagingTemplate template) {
        this.template = template;
    }       
    @MessageMapping("/vehicle")
    @SendTo("/topic/location")
    public void getloc() throws Exception {
        try {
            for (int i = 0; i < 10; i++) {
                template.convertAndSend("/topic/location", "aaaaaaa");
            }
        } catch (Exception e) {
            log.error(e);
        }
    }
}

这是我的web配置:

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("/vehicle").withSockJS();           
    }
}

这是客户端代码:

function connect() {
        var socket = new SockJS('/clbs/vehicle');
        stompClient = Stomp.over(socket);
        stompClient.connect({}, function (frame) {
            setConnected(true);
            console.log('Connected: ' + frame);
            stompClient.subscribe('/topic/location', function (greeting) {
                showGreeting(JSON.parse(greeting.body).content);
            });
        });
    }
stompClient.send("/app/vehicle",{},JSON.stringify("bbb"));

我该怎么办?哪里出了问题?

PS:控制器WebSocketController已经自动扫描。

JDK:

1.8Tomcat: 8.0.36春天:4.2.6

这个问题我已经纠结了2天了

确保控制器自动扫描成功。我遇到这个问题是因为bean没有扫描。因此无法匹配属性方法来处理stomp客户端请求。检查自动扫描配置。搜索历史日志内容，汇总的详细信息在这里。
