A personal understanding of aspect-oriented programming (AOP) in spring

Programming AOP for Facets is a major feature of spring

Aspect Facets: A (Enhanced) class that encapsulates the functionality of a common feature

Advice by: A method of encapsulating enhancements in a slice class.

PointCut: A pointcut, is the concept of a collection that expresses using a regular expression

Before and after all the methods of all core business objects (transactional AOP typical applications)

Joinpoint: Connection point, where the program needs to join advice, and the ponitcut being executed

Weaving (Weaving): The process of integrating aspect and core business objects.

Implementing AOP through specific interfaces

Types of AOP Notifications:

Before: front-facing notification

After: Post notification

Around: Surround Notifications

Throwing: Exception notification

Here is a common example of life: cut watermelon = aspect-oriented programming AOP

Cut the watermelon first to have a knife, and this knife is like writing a need to cut the various methods

Configure the appropriate pointcuts in the configuration file

Then, cut down = Execute the program, when the program executes, the chopper (slice) becomes part of the watermelon (object) and is executed by a piece.

In the simplest sentence, the service layer is cut in half and the log and transaction commits are added.
