我试图在我的项目中实现这个guide,这是一个spring-mvc项目但是只要我添加了类WebSocketConfig,就会给出以下异常:

Failed to start bean 'simpleBrokerMessageHandler'; nested exception is java.lang.IllegalArgumentException: can't serialize class org.springframework.messaging.simp.broker.BrokerAvailabilityEvent

更新:这是WebSocketConfig类:

@Configuration
@EnableWebSocketMessageBroker
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {
    @Override
    public void configureMessageBroker(MessageBrokerRegistry config) {
        config.enableSimpleBroker("/topic");
        config.setApplicationDestinationPrefixes("/calcApp");
    }
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        registry.addEndpoint("/add").withSockJS();
    }
}
