preface The last chapter introduces the development process and practical application of Io. When talking about the multithreading model of multiplexer, I have gone through it. This chapter will supplement here, and then go to Netty's IO model. Finally, the idea will be realized through code. 1, Introduce In the previous chapter, a multiplex ...

brief introductionWe know that the foundation of netty is channel and the selector on channel.
