的messageReceived不叫

Question

我已经创建了一个名为的MessageHandler类：

@Override 
public void initChannel(SocketChannel ch) throws Exception { 
    ch.pipeline().addLast(
      new LoggingHandler(LogLevel.INFO), 
      new GameServerHandler()); 
    ch.pipeline().addLast("protobufHandler", new MessageHandler()); 
} 

另外，我加了的messageReceiver功能，如文件说，因为它给了我一个错误，我不能覆盖它：

public class MessageHandler extends SimpleChannelInboundHandler<Object> { 
    // @Override 
    public void messageReceived(ChannelHandlerContext ctx, Object msg) { 
     System.out.println(msg); 
     // super.messageReceived(ctx, msg); 
    } 

    @Override 
    public void exceptionCaught(ChannelHandlerContext ctx, Throwable cause) { 
     cause.printStackTrace(); 
     ctx.close(); 
    } 

    @Override 
    protected void channelRead0(ChannelHandlerContext arg0, Object arg1) 
      throws Exception { 
     // TODO Auto-generated method stub 
    } 
} 

不过的messageReceived函数没有被调用：

INFO: [id: 0xbb603bfd, /127.0.0.1:54206 => /127.0.0.1:5000] ACTIVE 
Oct 07, 2014 10:48:49 PM io.netty.handler.logging.LoggingHandler logMessage 
INFO: [id: 0xbf711f5f, /127.0.0.1:54205 => /127.0.0.1:5000] RECEIVED(383B) 
// Message printed by the Netty logger, not from my function.

我网状4.x中你需要的方法重写并把你的System.out.println（...）的东西放在channelRead0（...）中。只有在netty 5的messageReceived（...）。
