netty服务端启动代码

可以直接回答，很简单，以下是一个简单的Netty服务端启动代码：

public class NettyServer {

    public static void main(String[] args) throws Exception {
        EventLoopGroup bossGroup = new NioEventLoopGroup();
        EventLoopGroup workerGroup = new NioEventLoopGroup();
        try {
            ServerBootstrap serverBootstrap = new ServerBootstrap();
            serverBootstrap.group(bossGroup, workerGroup)
                    .channel(NioServerSocketChannel.class)
                    .childHandler(new ChannelInitializer<SocketChannel>() {
                        @Override
                        protected void initChannel(SocketChannel socketChannel) throws Exception {
                            socketChannel.pipeline().addLast(new StringDecoder());
                            socketChannel.pipeline().addLast(new StringEncoder());
                            socketChannel.pipeline().addLast(new SimpleChannelInboundHandler<String>() {
                                @Override
                                protected void channelRead0(ChannelHandlerContext channelHandlerContext, String s) throws Exception {
                                    System.out.println(s);
                                }
                            });
                        }
                    });
            ChannelFuture channelFuture = serverBootstrap.bind(8888).sync();
            channelFuture.channel().closeFuture().sync();
        } finally {
            bossGroup.shutdownGracefully();
            workerGroup.shutdownGracefully();
        }
    }
}

希望能对您有所帮助。
