本文介绍了如何使用Netty在Java中创建一个简单的服务端和客户端网络应用，包括ServerBootstrap配置、ChannelInitializer和Bootstrap连接设置。

服务端

public class NettyBootstrap {
    public static void main(String[] args) throws InterruptedException {
        NioEventLoopGroup boss = new NioEventLoopGroup();
        NioEventLoopGroup worker = new NioEventLoopGroup();
        ServerBootstrap serverBootstrap = new ServerBootstrap();
        try {
            serverBootstrap.group(boss, worker)
                    .channel(NioServerSocketChannel.class)
                    .handler(new LoggingHandler())
                    .childHandler(new ChannelInitializer<SocketChannel>() {
                        @Override
                        protected void initChannel(SocketChannel socketChannel) {
                            socketChannel.pipeline().addLast(new CustomChannelHandler());
                        }
                    });
            final ChannelFuture sync;
            sync = serverBootstrap.bind(8080).sync();
            sync.channel().closeFuture().sync();
        } catch (InterruptedException e) {
            e.printStackTrace();
        } finally {
            boss.shutdownGracefully().sync();
            worker.shutdownGracefully().sync();
        }
    }
}

客户端

NioEventLoopGroup work = new NioEventLoopGroup();
        bootstrap = new Bootstrap();
        bootstrap.group(work)
                .channel(NioSocketChannel.class)
                .option(ChannelOption.CONNECT_TIMEOUT_MILLIS, 15000)
                .handler(websocketInitializer);
                //.handler(initializer);
    	String host="127.0.0.1";
    	int port = 8080;
        bootstrap.connect(host,port).channel();
