Spring AOP has good support for exception handling. Spring
I haven't used spring for a long time. Suddenly picked up the book. I found myself unfamiliar with AOP.In fact, the meaning of AOP is to face-slicing programming.OO focuses on our approach to problem solving (encapsulated into method), while AOP
