Multithreaded Programming Learning (9) Worker pattern mode

Worker pattern[Working mode]
One: Participants in Worker pattern
--->client (principal thread)
--->channel (channel, inside, storage queue for request)
--->request (packaging of work contents)
--->worker (worker thread)


Two: When the Worker pattern pattern is used
---> Similar producer consumers


Three: Worker pattern thinking


Four step instructions
---> Worker threads take out the requested content after wrapping, depending on polymorphism, different requests execute different business methods
