Netty 未调用ChannelRead 我有一个现有的应用程序，它使用java套接字连接到C++服务器，发送请求和读取响应，我尝试将java套接字转换成基于网络的连接。

我有一个netty客户端，我正在通过netty客户端发送相同的请求，我可以看到请求正在发送，并且没有调用我的通道读取来读取服务器的响应

我在netty日志中看到FLUSH、READ COMPLETE、FLUSH、INACTIVE和unregisted

我需要关于为什么不调用clients channel read方法的帮助

我使用的是Netty 4.1.10.Final，下面是客户端和客户端处理程序代码

public ChannelFuture connectLoop() throws Exception {
    EventLoopGroup group = new NioEventLoopGroup();
    try {
        Bootstrap clientBootstrap = new Bootstrap();

        clientBootstrap.group(group);
        clientBootstrap.channel(NioSocketChannel.class);
        clientBootstrap.option(ChannelOption.SO_KEEPALIVE, true);
        clientBootstrap.option(ChannelOption.TCP_NODELAY, true);
        clientBootstrap.remoteAddress(new InetSocketAddress("127.0.0.1", 8888));
        clientBootstrap.handler(new ChannelInitializer<SocketChannel>() {
            @Override
            protected void initChannel(SocketChannel socketChannel) throws Exception {
                //socketChannel.pipeline().addLast( new StringDecoder() ,new StringEncoder()  , new LineBasedFrameDecoder(1024), new ChannelHandlerAdapter(){
                socketChannel.pipeline().addLast("framer", new LengthFieldBasedFrameDecoder(1000000,0,4,0,4));//16KB

                socketChannel.pipeline().addLast("logger", loggingHandler);
               socketChannel.pipeline().addLast("frameDecoder", new LengthFieldBasedFrameDecoder(1048576, 0, 4, 0, 4));
               socketChannel.pipeline().addLast("bytesDecoder", new ByteArrayDecoder());

                // Encoder
                socketChannel.pipeline().addLast("frameEncoder", new LengthFieldPrepender(4));
                socketChannel.pipeline().addLast("bytesEncoder", new ByteArrayEncoder());
                socketChannel.pipeline().addLast(new NettyClientHandler());




            }
        });
        ChannelFuture channelFuture = clientBootstrap.connect().sync();

        this.channel = channelFuture.channel();
        //channelFuture.channel().closeFuture().sync();
        return channelFuture;

    } finally {

    }



}


    public void shutdown() {
        workGroup.shutdownGracefully();
    }

}



public class NettyClientHandler extends ChannelInboundHandlerAdapter {

   @Override
    public void channelReadComplete(ChannelHandlerContext ctx) throws Exception {
        System.out.println("Invoked -------------- > channel read complete");
        ctx.flush();
    }

    @Override
    public void channelActive(ChannelHandlerContext channelHandlerContext) throws Exception {
        System.out.println("Invoked -------------- > Channel Active");


        super.channelActive(channelHandlerContext);

    }



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


    @Override
    public void channelRead(ChannelHandlerContext channelHandlerContext, Object msg) throws Exception {
        System.out.println("Invoked -------------- > channel read");
        System.out.println("Client received:" + msg.toString());
        channelHandlerContext.close();
    }


}

完成后，

writeAndFlush

返回的

ChannelFuture

的结果是什么？ChannelFuture的结果是成功的我将在

ChannelPipeline

中添加一个

LoggingHandler

作为第一个，然后查看是否收到任何消息。管道atm中有很多处理程序，因此很难判断哪个在缓冲。感谢诺曼的回复，添加logginghandler作为通道管道中的第一行，可以得到相同的日志。。我看到一个刷新，然后一个读取完成。。我看不到频道被调用了。。还有其他建议吗？还有其他想法吗？我被这件事缠住了，不能继续下去

NettyClient nettyClient = new NettyClient(10500);
        ChannelFuture channelFuture = nettyClient.connectLoop();
        channelFuture.channel().writeAndFlush((msg)).addListener(ChannelFutureListener.FIRE_EXCEPTION_ON_FAILURE);
