Netty Server 启动时序图

正常启动netty Server端代码如下

// 配置服务端的NIO线程组
    EventLoopGroup bossGroup = new NioEventLoopGroup();
    EventLoopGroup workerGroup = new NioEventLoopGroup();
    ServerBootstrap b = new ServerBootstrap();
    b.group(bossGroup, workerGroup).channel(NioServerSocketChannel.class)
        .option(ChannelOption.SO_BACKLOG, 100)
        .handler(new LoggingHandler(LogLevel.INFO))
        .childHandler(new ChannelInitializer<SocketChannel>() {
            @Override
            public void initChannel(SocketChannel ch)
                throws IOException {
            ch.pipeline().addLast(
                new NettyMessageDecoder(1024 * 1024, 4, 4));
            ch.pipeline().addLast(new NettyMessageEncoder());
            ch.pipeline().addLast("readTimeoutHandler",
                new ReadTimeoutHandler(50));
            ch.pipeline().addLast(new LoginAuthRespHandler());
            ch.pipeline().addLast("HeartBeatHandler",
                new HeartBeatRespHandler());
            }
        });

    // 绑定端口，同步等待成功
    b.bind(NettyConstant.REMOTEIP, NettyConstant.PORT).sync();
