1. 該啟動方式無需單獨開線程啟動netty,dubbo的NettyService就是此方式

  public static void main(String[] args) {
        ServerBootstrap serverBootstrap = new ServerBootstrap();
        // boos接受新連接線程，主要負責創(chuàng)建新連接(從dubbo copy 過來)
        NioEventLoopGroup boos = new NioEventLoopGroup(1,
                new DefaultThreadFactory("NettyServerBoss", true));
        // worker負責讀取數(shù)據(jù)的線程，主要用于讀取數(shù)據(jù)以及業(yè)務邏輯處理(從dubbo copy 過來)
        NioEventLoopGroup worker = new NioEventLoopGroup(10,
                new DefaultThreadFactory("NettyServerWorker", true));
        try {
            serverBootstrap
                    .group(boos, worker)
                    .channel(NioServerSocketChannel.class)
                    .childHandler(new SimpleServiceChannelInitializer());

            ChannelFuture channelFuture = serverBootstrap.bind(10086);
            channelFuture.syncUninterruptibly();
            channelFuture.channel();
          //該啟動方式為了阻塞主線程
            Thread.sleep(200000);
        } catch (Exception e) {

        } finally {
            boos.shutdownGracefully();
            worker.shutdownGracefully();
        }

    }
