Question

我正在使用服务器，每个请求都创建自己的堆栈现在我有主对象，我将它传递给每个请求创建方法。这个主对象lts称之为：GameManager拥有名为GameRooms的嵌套Map对象并且每个房间都有嵌套对象（Map），称为玩家
像这样的东西：

public  class GameManager {
    private final Map<Integer, GameRoom> gameRooms; 
    public GameManager (Map<Integer, GameRoom> _gameRooms)
    {
      gameRooms = _gameRooms;
       create only 1 room 
    gameRooms.put(0,new  GameRoom());
    }
}

public class GameRoom {
      private final Map<Integer, Player> players;
      public GameRoom() 
      {
           players = new HashMap<Integer, Player>();
      }
      public Map<Integer, Player>  getPlayers()
      {
         return players;
      }
}

public int setPlayer(Player _player)
{
    int playerId = _player.getID();
    this.players.put(playerId,_player);   // THIS doesn't keep the player reference
    // //this.players.put(playerId,new Player(_player.getID())); // THIS also doesn't keep the player reference when i do New
}


public class Player {
   private int id;
   public Player (int _id)
   {
       id = _id
   } 
   public int getID() 
   {
      return id
   }
}

服务器类

public class GameServerInitializer extends ChannelInitializer<Channel> {
    private final GameManager gameManager; 
    private int i ;
    public GameServerInitializer(GameManager _gameManager) {
        this.gameManager = _gameManager;
        i = 0;
    }
    //this called on each request 
    public void Request()
    {
          Player p = new Player(i++); 
          //if it the first request it will be 0
          int s = this.gameManager.getGameRooms().get(0).getPlayers().size();
          this.gameManager.getGameRooms().get(0).setPlayer(p);
          //now it is 1 on the first request 
          int s1 = this.gameManager.getGameRooms().get(0).getPlayers().size();

    }

}

现在从主服务器启动时

private final Map<Integer, GameRoom> gameRooms = new HashMap<Integer, GameRoom>();
private final GameManager gameManager = new GameManager(gameRooms); 
new GameServerInitializer(gameManager);

现在我期待着。this.gameManager.getGameRooms（）得到（0）.getPlayers（）大小（）。将累积每个请求将添加1个玩家到GameRoom 但是每个请求的大小都不是0 这只适用于玩家，游戏室地图确实在请求中保持其大小

Java对嵌套成员的引用迷失了，试图避免单圈
