如何共享 ByteToMessageDecoder？

Question

我有一个扩展 ByteToMessageDecoder that's also marked as shareable via the ChannelHandler.Sharable annotation. However I encounter a runtime error with the following stack trace which is because the constructor of ByteToMessageDecoder invokes ensureNotSharable() 的解码器 class。为什么会这样，是否可以创建共享解码器？

Answer 1

来自 ByteToMessageDecoder 的文档：

Be aware that sub-classes of ByteToMessageDecoder MUST NOT annotated with @Sharable.

无法共享解码器。要解决此问题，请实例化一个新的解码器。
