我在原有的项目当中按照官方的例子集成了spring websocket，没有报错，但是项目无法启动

我的项目是sring+springMVC+Mybatis,JDK为1.7，tomcat 7 按照官方的例子spring web socket demo搞了好几天了，一直是这样，有木有大神帮我看看是怎么回事

主要的代码在这里
@Configuration
@EnableWebSocketMessageBroker
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("/hello").withSockJS();
}

这是我的pom文件
