Question

我目前正在尝试学习netty，但没有任何作用......）：不知何故，服务器没有从客户端收到任何消息，我不知道为什么。请记住，我从未在netty中构建一个有效的应用程序，所以我绝对没有经验。如果有人可以帮助我，我会很高兴。我发布了很多代码，我很抱歉，但我不知道如何使这个问题变小。

所以，这是我的代码：

    new Server().run();
    Client client = new Client();
    client.run();

    while(true){
        System.out.println("sending message to server...");
        client.sendMessage(new PacketPing(System.currentTimeMillis()));
        Thread.sleep(1000);
    }

这是我的客户：

private Channel channel;
@Override public void run() {
    ChannelFuture future = new Bootstrap().
            group(new NioEventLoopGroup()).
            channel(NioSocketChannel.class).
            handler(new ChannelInitializer<SocketChannel>() {
                @Override protected void initChannel(SocketChannel ch) throws Exception {
                    ch.pipeline().addLast(
                            new ObjectEncoder(),
                            new ObjectDecoder(ClassResolvers.cacheDisabled(null)),
                            new ChannelInboundHandlerAdapter() {
                                @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
                                    System.out.println("client received message!");
                                }
                            });
                }
            }).connect("localhost", 40401);
    try {
        future.get();
    } catch (InterruptedException | ExecutionException e) {
        e.printStackTrace();
    }
    this.channel = future.channel();
}
public void sendMessage(Object msg) {
    channel.writeAndFlush(msg);
}

这是我的服务器：

@Override public void run() {
    new ServerBootstrap().
            group(new NioEventLoopGroup(1), new NioEventLoopGroup()).
            channel(NioServerSocketChannel.class).
            handler(new LoggingHandler(LogLevel.INFO)).
            childHandler(new ChannelInitializer<SocketChannel>() {
                @Override protected void initChannel(SocketChannel ch) throws Exception {
                    ch.pipeline().addLast(
                            new ObjectEncoder(),
                            new ObjectDecoder(ClassResolvers.cacheDisabled(null)),
                            new ChannelInboundHandlerAdapter() {
                                @Override public void channelRead(ChannelHandlerContext ctx, Object msg) throws Exception {
                                    System.out.println("server received a message!");
                                }
                            });
                }
            }).bind(40401);
}

我认为我缺少一些基本的理解，我不知道从哪里开始调试。代码非常简单，所以每个熟悉netty的人都应该很容易回答这个问题（：谢谢@everybody！
