老哥，还能私下请教你点问题呀，我qq786744873 答案666666

有个地方不是很明白，netty的ChildHandler是否意味着一个新的连接上来创建一个handler，该连接直到断开前都是这个handler，还是每次send消息后一个新的handler，如果是前者的话，是不是意味着该NettyTcpServerHandler实例handler实例的相关的构造函数注入的参数伴随着channel连接到断开的整个周期，如果相关的NettyTcpServerHandler中包含有相关的数据库连接等对象时，是不是意味着1W个连接，创建1W个数据库连接实例，在连接断开前一直不会被释放呢呢？

bootstrap .Option(ChannelOption.SoBacklog, configuration.SoBacklog) .ChildOption(ChannelOption.Allocator, serverBufferAllocator) .ChildHandler(new ActionChannelInitializer<IChannel>(channel => { IChannelPipeline pipeline = channel.Pipeline; using (var scope = serviceProvider.CreateScope()) { channel.Pipeline.AddLast("jt808TcpBuffer", new DelimiterBasedFrameDecoder(int.MaxValue, Unpooled.CopiedBuffer(new byte[] { JT808.Protocol.JT808Package.BeginFlag }), Unpooled.CopiedBuffer(new byte[] { JT808.Protocol.JT808Package.EndFlag }))); channel.Pipeline.AddLast("jt808TcpDecode", scope.ServiceProvider.GetRequiredService<UnionTcpDecoder>()); channel.Pipeline.AddLast("jt808TcpEncode", scope.ServiceProvider.GetRequiredService<UnionTcpEncoder>()); channel.Pipeline.AddLast("systemIdleState", new IdleStateHandler( configuration.ReaderIdleTimeSeconds, configuration.WriterIdleTimeSeconds, configuration.AllIdleTimeSeconds)); channel.Pipeline.AddLast("jt808TcpConnection", scope.ServiceProvider.GetRequiredService<NettyTcpConnectionHandler>()); channel.Pipeline.AddLast("jt808TcpService", scope.ServiceProvider.GetRequiredService<NettyTcpServerHandler>()); } }));
