package com.tievd.cloud.vbp.message.config;

@Configuration
@EnableWebSocketMessageBroker
@Order(Ordered.HIGHEST_PRECEDENCE + 99)
public class WebSocketConfig extends AbstractWebSocketMessageBrokerConfigurer {

    private Log LOG = LogFactory.getLog(WebSocketConfig.class);

    /**
     * 定义服务器端接改地址
     *
     * @param registry
     */
    @Override
    public void registerStompEndpoints(StompEndpointRegistry registry) {
        //服务端点接收客户端的连接
        registry.addEndpoint("/notify").setAllowedOrigins("*").withSockJS().setClientLibraryUrl("../js/1.1.4/sockjs.min.js");
    }

    /**
     * 定义服务器端发送地址
     *
     * @param config
     */
    @Override
    **public void configureMessageBroker(MessageBrokerRegistry config) {
        //客户端给服务端发消息的地址的前缀
        config.setApplicationDestinationPrefixes("/app");
        //客户端接收服务端消息的地址的前缀信息
        config.enableSimpleBroker("/topic", "/queue");
    }**
}

在以上服务端配置的情况下，js也有相应的写法：
连接websocket：很明显对应者registerStompEndpoints方法里的配置notify

var socket = new SockJS("http://master:8989/msg/notify/?access_token=" + token);

订阅：对应于enableSimpleBroker方法

                stompClient.subscribe('/user/queue/face_compare', function(greeting){

客户端向服务端发送消息：对应与setApplicationDestinationPrefixes方法

     stompClient.send("/app/hello", {atytopic:"greetings"}, JSON.stringify({ 'name': name }));
