当ChannelDuplexHandler写方法是最后一个处理程序时,应该调用它,但实际上它不是。
来自,
ChannelPipeline p = ...;
p.addLast("1", new InboundHandlerA());
p.addLast("5", new InboundOutboundHandlerX());
入站事件和出站事件的评估顺序分别为1、5和5。
因此,我认为当调用ctx.write() in channelRead时,应该调用以下类中的ctx.write():
@ChannelHandler.Sharable
@Compone

at my wedding
We will PATTERN

all are welcome
