Question

如果是客户端连接的同步TCP服务器，我会获得客户端示例的引用：

 int serverPortNum = 9000;
socket while(true) {
     ServerSocket connectionSocket = new ServerSocket(serverPortNum);
     Socket dataSocket = connectionSocket.accept( );
     // pass this reference(dataSocket ) to other part of program to read or write depending on app logic
}

现在我想使用Netty使用异步TCP服务器，所以我可以通过任何方式获得连接新客户端时创建的ChannelPipeline或ChannelHandler的引用。

在客户端，我可以轻松完成：示例代码： NioClientSocketChannelFactory ncscf = new NioClientSocketChannelFactory（Executors.newCachedThreadPool（），Executors.newCachedThreadPool（））; ClientBootstrap clientBootstrap = new ClientBootstrap（ncscf）;

    final DummyHandler  dummy = new DummyHandler();
    clientBootstrap.setPipelineFactory(new ChannelPipelineFactory() { 
        @Override
        public ChannelPipeline getPipeline() throws Exception { 
            return Channels.pipeline(dummy); 
        } 
    }); 

    InetAddress inetaddress = InetAddress.getByName(host);
    ChannelFuturecf=clientBootstrap.connect(newInetSocketAddress(inetaddress,port));

因此，每次创建新客户端时，我都会有新的DummyHandler参考

在服务器端：示例代码： ServerBootstrap bootstrap = new ServerBootstrap（新的NioServerSocketChannelFactory（ Executors.newCachedThreadPool（） Executors.newCachedThreadPool（）））;

    bootstrap.setPipelineFactory(new ChannelPipelineFactory() {
        public ChannelPipeline getPipeline() throws Exception {
            return Channels.pipeline(new DummyServerHandler());
        }
    });


    bootstrap.bind(new InetSocketAddress(port));
   So when client request connection new DummyServerHandler object is created but i cannot get reference of this.

我可能会错过这个问题，但不会这样做。

Channel.getpipeline()

当客户端连接到服务器端的服务器时，有没有办法获得ChannelPipeline的引用？
