websocket 连接发消息成功都进了AbstractWsEndpoint 里的方法 ,但是不进入WkWebSocket 里的onMessage方法

自行看onMessage的方法参数,同名还得同参数才能覆写的

重写后参数一致可以了 不过重写的onOpen这个方法要怎么接收传过来的参数呢
这个是原版的写法

@ServerEndpoint("/open/api/pc/live/websocket/{uid}")
public class ApiPcLiveWebSocket {

    protected LiveCommentService liveCommentService = SpringUtil.getBean("liveCommentServiceImpl", LiveCommentService.class);
    protected AccountInfoService accountInfoService = SpringUtil.getBean("accountInfoServiceImpl", AccountInfoService.class);
    protected LiveService liveService = SpringUtil.getBean("liveServiceImpl", LiveService.class);
    protected LiveWatchService liveWatchService = SpringUtil.getBean("liveWatchServiceImpl", LiveWatchService.class);

    private static Map<String, ApiPcLiveWebSocket> clients = new ConcurrentHashMap<String, ApiPcLiveWebSocket>();
    private Session session;
    private String username;
    private String liveId;

    @OnOpen
    public void onOpen(@PathParam("uid")String uid , Session session) throws IOException {

        this.username = uid;
        this.session = session;
        if(clients.get(username) == null){
            clients.put(username, this);
        }
    }

nutzBoot版是这样的:

 @Override
    public void onOpen(Session session, EndpointConfig config) {

//        this.username = config.toString();
        this.session = session;
        if(clients.get(username) == null){
            clients.put(username, this);
        }
    }

我找到了 EndpointConfig config 这里有 pathParamMap

突然又发现EndpointConfig里的这个pathParamMap属性获取不到 @wendal

原版可以的话,用原版+configurer类就好啦
