java - 在kryonet中发送和接收数组

我正在使用kryonet创建一个服务器/客户端系统。
我正在尝试从服务器向我的客户端发送int[][]。为了完成这项任务,我尝试了:

publc class ArrayPacket {
 public int[][] array
}

然后,在服务器侦听器中我写道:
ArrayPacket myPacket = new ArrayPacket();
for (int y = 0; y < Level.height; y++) {
    for (int x = 0; x < Level.width; x++) {
        myPacket.id[x][y] = somethingAt[x][y];
    }
}
clientConnection.sendTCP(myPacket);

最后,在客户端侦听器中,我接收到arraypacket:
public void received(Connection con, Object object) {
            if (object instanceof ArrayPacket) {
                for (int y = 0; y < Level.height; y++) {
                    for (int x = 0; x < Level.width; x++) {             
                        somethingAt[x][y] = ((ArrayPacket) object).array[x][y];
                    }
                }
            }
        }

我把所有东西都登记了:
public void register(Kryo k) {
    k.register(ArrayPacket.class);
    k.register(int[][].class);
}

但是,当我运行它时,会抛出一个错误,告诉我必须注册int[].class。所以我这样做,再次运行程序,编译器抛出一个bufferoverflowexception:

那么,我怎样才能纠正这个错误呢?
提前谢谢。


最佳答案:

我解决了这个问题。这很简单:我只是增加了服务器和客户机可以接收的数据量。
