netty同时支持socket和http

项目需要使用netty做中转服务器，同时支持两种不同协议的客户端，经过几天查询资料终于找到合适的方案了，同时感谢Netty权威指南及论坛问答,开始贴代码

客户端1==》socket

public class Bluetooth implements Runnable {
    //蓝牙
 
    private int port;
    @Override
    public void run() {
        System.out.println("--------进入蓝牙---------");
        EventLoopGroup bossGroup = new NioEventLoopGroup();
        EventLoopGroup workGroup = new NioEventLoopGroup();
        try {
            ServerBootstrap b = new ServerBootstrap();
            b.group(bossGroup, workGroup);
            b.channel(NioServerSocketChannel.class);
            b.childHandler(new ChannelInitializer<SocketChannel>() {
                @Override
                public void initChannel(SocketChannel ch) throws Exception {
                    System.out.println("chhhh"+ch.id());
                            // 注册handler
                            /*ch.pipeline().addLast("http-codec", new HttpServerCodec());
                            ch.pipeline().addLast("aggregator", new HttpObjectAggregator(65536));
                            ch.pipeline().addLast("http-chunked", new ChunkedWriteHandler());*/
                    ch.pipeline().addLast(new SimpleServerHandler());
                }
            });
//            b.childHandler(new ChannelFilter());
            System.out.println("平台监听开启....");
            Channel ch = b.bind(5500).sync().channel();
            ch.closeFuture().sync();
 
        } catch (Exception e) {
            e.printStackTrace();
        }finally{
            //优雅的退出程序
            bossGroup.shutdownGracefully();
            workGroup.shutdownGracefully();
        }
    }

客户端2==》http

public class Myweb implements Runnable {
    //Myweb
 
    private int port;
    @Override
    public void run() {
        System.out.println("--------进入web---------");
        EventLoopGroup bossGroup = new NioEventLoopGroup();
        EventLoopGroup workGroup = new NioEventLoopGroup();
        try {
            ServerBootstrap b = new ServerBootstrap();
            b.group(bossGroup, workGroup);
            b.channel(NioServerSocketChannel.class);
            b.childHandler(new ChannelInitializer<SocketChannel>() {
                @Override
                public void initChannel(SocketChannel e) throws Exception {
                    System.out.println("chhhh"+e.id());
                    e.pipeline().addLast("http-codec", new HttpServerCodec());
                    e.pipeline().addLast("aggregator", new HttpObjectAggregator(65536));
                    e.pipeline().addLast("http-chunked", new ChunkedWriteHandler());
                    e.pipeline().addLast(new SimpleServerHandler());
                }
            });
//            b.childHandler(new ChannelFilter());
            System.out.println("平台监听开启....");
            Channel ch = b.bind(8888).sync().channel();
            ch.closeFuture().sync();
 
        } catch (Exception e) {
            e.printStackTrace();
        }finally{
            //优雅的退出程序
            bossGroup.shutdownGracefully();
            workGroup.shutdownGracefully();
        }
    }
}

main==>开启两个监听线程

public class main {
    private int port;
 
    public main(int port) {
        this.port = port;
    }
 
    public void run() throws Exception {
 
    }
 
    public static void main(String[] args) throws Exception {
//        new main(5500).run();
        Bluetooth bluetooth = new Bluetooth();
        Myweb myweb = new Myweb();
 
        Thread th1 = new Thread(bluetooth);
        Thread th2 = new Thread(myweb);
        th1.start();
        th2.start();
 
    }
}

Handler代码就不贴了，网上很多，主要是通过多线程分别使用不同编解码器，

对不同客户端的协议进行解析。同时将Chnnel通道保存在Map集合中，两个线程可共享这个Chnnel。
