WebSoket一对多聊天(仅供参考)

soket通过Session来记录会话,通话一般首先要解决的是,这条消息由谁发给谁,所以我为此创建了一个实体类代码如下:

//如果没有使用lombok请自己生成get,set方法
@Data
public class SocketMsg {
    private String My;  //用于记录我的Id
    private String passageway;   //频道
    private String fromUser;//发送者.
    private String toUser;//接受者.
    private String msg;//消息
}

上面的频道我用于存游客id,因为我是一对多所以我要单独维护我的id,接下来就是Soket类

//nickname用于传用户名不需要可以去掉
@ServerEndpoint(value = "/websocket/{nickname}")
@Component
public class MyWebSocket {

    //用来记录sessionId和该session进行绑定
    private static Map<String,Session> map = new HashMap<String, Session>();

    //用来存放每个客户端对应的MyWebSocket对象。
    private static CopyOnWriteArraySet<MyWebSocket> webSocketSet = new CopyOnWriteArraySet<MyWebSocket>();


    //我把自己取名为老中医,这是我自己会话
    private static Session laoZhongYi;

    //与某个客户端的连接会话,需要通过它来给客户端发送数据
    private Session session;

    private String username;




    /**
     * 连接建立成功调用的方法
     */
    @OnOpen
    public void onOpen(Session session,@PathParam("nickname") String nickname) {
        SocketMsg socketMsg = new SocketMsg();
         //如果是不是我自己上线
        if (!"老中医".equals(nickname)){
            this.session = session;
            this.username = nickname;
            webSocketSet.add(this);     //加入set中
            map.put(session.getId(), session);
            System.out.println("有新连接加入:"+session.getId()+"当前在线人数为" + webSocketSet.size());
            socketMsg.setPassageway(session.getId());
            this.session.getAsyncRemote().sendText(JSON.toJSONString(socketMsg));
            laoZhongYi.getAsyncRemote().sendText(JSON.toJSONString(socketMsg));
            //        this.session.getAsyncRemote().sendText("恭喜"+session.getId()+"成功连接上WebSocket(其频道号:"+session.getId()+")-->当前在线人数为:"+webSocketSet.size());
        }else {
            //我上线就加入会话
            laoZhongYi = session;
            socketMsg.setLaoZonYiId(laoZhongYi.getId());
            socketMsg.setMsg("老中医连接成功");
            laoZhongYi.getAsyncRemote().sendText(JSON.toJSONString(socketMsg));
        }

    }
    /**
     * 连接关闭调用的方法
     */
    @OnClose
    public void onClose() {
        webSocketSet.remove(this);  //从set中删除
        map.remove(this.session.getId());
        System.out.println("有一连接关闭!当前在线人数为" + webSocketSet.size());
    }
