$(function () {
    var ws = new WebSocket('ws://' + location.host + '/chat');
    //....
});

// WebSocket
@BeanWebSocketConfigurer createWebSocketConfigurer(@Autowired ChatHandler chatHandler, @Autowired ChatInterceptor chatInterceptor) {
   return new WebSocketConfigurer() {
      @Override      
      public void registerWebSocketHandlers(WebSocketHandlerRegistry webSocketHandlerRegistry) {
         webSocketHandlerRegistry.addHandler(chatHandler, "/chat").addInterceptors(chatInterceptor);      
      }
   };
}

读完这篇文章有2处不懂的问题

这段代码，仅调用了父类 HttpSessionHandshakeInterceptor 的构造方法，是怎么做到从 HttpSession 复制属性到 WebSocketSession ？源码跟迷路了。。。

@Component
public class ChatHandshakeInterceptor extends HttpSessionHandshakeInterceptor {
    public ChatHandshakeInterceptor() {
        // 指定从HttpSession复制属性到WebSocketSession:
        super(List.of(UserController.KEY_USER));
    }
}

另一个问题是：浏览器请求一个WebSocket连接后，如果成功建立连接，WebSocketSession 接口的实例从哪取得？装配的实例是哪个类？

public void afterConnectionEstablished(WebSocketSession session) throws Exception { ...
