我使用 netty 3.5.8 创建了一个游戏服务器。起初,从服务器向客户端发送数据没有任何问题。但是当服务器运行一段时间后,java.nio.channels.ClosedChannelException
我向客户端通道写入数据时会出现很多异常[ ]。
任何人以前都遇到过这个例外。有什么提示可以解决这个问题吗?我认为缓存缓冲区导致了这个。
我的代码示例如下:
ChannelBuffer bff = ChannelBuffers.buffer(18);
bff.writeByte(Events.S_SERVER_PUSH);
bff.writeByte((byte)0);
bff.writeInt(idRoom);
bff.writeInt(playerCnt);
bff.writeInt(gameCnt);
bff.writeInt(freePlayer);
channel.write(bff);
异常:java.nio.channels.ClosedChannelException
