Netty ServerBootstrap 绑定多个端口（代码示例）

EventLoopGroup bossGroup = new NioEventLoopGroup();
        EventLoopGroup workerGroup = new NioEventLoopGroup();
        try {
            ServerBootstrap b = new ServerBootstrap();
            b.group(bossGroup, workerGroup)
             .channel(NioServerSocketChannel.class)
             .childHandler(new ChannelInitializer<SocketChannel>() {
                 @Override
                 public void initChannel(SocketChannel socketChannel) throws Exception {
                     ChannelPipeline pipeline = socketChannel.pipeline();
                     pipeline.addLast("in2", new LengthFieldBasedFrameDecoder(Integer.MAX_VALUE, 0, 4, 0, 4));
                     pipeline.addLast("in1", new TimeDecoder());
                     pipeline.addLast("out0", new LengthFieldPrepender(4));
                     pipeline.addLast("out1", new TimeEncoder());
                     pipeline.addLast("in3", new TimeServerHandler());
                 }
             })
                    .option(ChannelOption.SO_BACKLOG, 128)
                    .childOption(ChannelOption.SO_KEEPALIVE, true);

            //绑定端口 开始接收连接
            //绑定多个端口
            ChannelFuture f = b.bind(port);
            ChannelFuture f1 = b.bind(8001);

            f.channel().closeFuture().sync();
            f1.channel().closeFuture().sync();

绑定多个端口代码：

            //绑定端口 开始接收连接
            //绑定多个端口
            ChannelFuture f = b.bind(port);
            ChannelFuture f1 = b.bind(8001);

            f.channel().closeFuture().sync();
            f1.channel().closeFuture().sync();
