netty 多端口多协议

netty监听多个端口（9090,9091），不同端口处理不同协议（TCP,HTTP）等

启动监听

public class Main {
    public static void main(String[] args) throws Exception {
        TCPServer server = new TCPServer(9090,9091);
        server.start();
    }
}

public class TCPServer {
    int tcp_port ;
    int http_port;

    public TCPServer(int tcp_port,int http_port){
        this.tcp_port = tcp_port;
        this.http_port = http_port;
    }

    public void start() throws Exception{
        ServerBootstrap bootstrap = new ServerBootstrap();
        EventLoopGroup boss = new NioEventLoopGroup(2);
        EventLoopGroup work = new NioEventLoopGroup(8);
        bootstrap.group(boss,work)
                .handler(new LoggingHandler(LogLevel.DEBUG))
                .channel(NioServerSocketChannel.class)
                .childHandler(new TCPServerInitializer());

        ChannelFuture f = bootstrap.bind(new InetSocketAddress(tcp_port)).sync();
        ChannelFuture f1 = bootstrap.bind(new InetSocketAddress(http_port)).sync();
        System.out.println(" server start up on port : " + tcp_port);
        System.out.println(" server start up on port : " + http_port);
        f.channel().closeFuture().sync();
        f1.channel().closeFuture().sync();
    }
}

public class TCPServerInitializer extends ChannelInitializer<SocketChannel> {

    @Override
    protected void initChannel(SocketChannel channel) throws Exception {
        ChannelPipeline pipeline = channel.pipeline();


        InetSocketAddress socketaddr = channel.localAddress();
        int port = socketaddr.getPort();
        if (port == 9090){
            System.out.println("端口9090");
            pipeline.addLast(new LengthFieldBasedFrameDecoder(4096,0,2,0,2));
            pipeline.addLast(new TCPRequestHandler());// 请求TCP处理器
        }else
        {
            System.out.println("端口9091");
            pipeline.addLast(new HttpServerCodec());// http 编解码
            pipeline.addLast("httpAggregator",new HttpObjectAggregator(512*1024)); // http 消息聚合器                                                                     512*1024为接收的最大contentlength
            pipeline.addLast(new HttpRequestHandler());// 请求HTP处理器
        }



    }
}

思路如上

public class TCPRequestHandler extends SimpleChannelInboundHandler {

    private static  byte[] isoMacKey = StringUtil.hexStr2Bytes("1111111111111111");
    @Override
    protected void channelRead0(ChannelHandlerContext ctx, Object msgIn) throws Exception {
        ByteBuf buf=(ByteBuf) msgIn;

        byte[] req=new byte[buf.readableBytes()];
        int reqLen = buf.readableBytes();
        buf.readBytes(req);
        if(req[0]!=0x60){
            return ;
        }
        System.out.println("服务器端接收的消息["+ HexUtil.toHex(req)+"]");
    }
}
