Spring Learning Note four: AOP

AOP (Aspect Orient programming), aspect-oriented programming is a complement to object-oriented programming oops

Object-oriented programming uses a static perspective to consider the structure of a program, while aspect-oriented programming is a dynamic consideration of the program's running process

The underlying AOP is implemented using dynamic proxy mode. Two kinds of proxies are used: Dynamic proxy domain cglib dynamic proxy of JDK

AOP Programming belongs to:

1. Facets (Aspect)

Tangent refers to cross-service logic

2. Weave in (weaving)

Weaving refers to the process of inserting slice code into a target object

3. Entry point (Pointcut)

A pointcut refers to the location of a plane's specific weave.

4. Destination object (target)

Target object refers to the object that will be enhanced

5. Notice (Advice)

Notification is a specific implementation of the aspect, can complete simple weaving function

6. Advisor (advisor)

A consultant is another implementation of a slice that can weave a notification into a target object in a more complex way, and is the assembler that wraps the notification as a more duplicated slice

Spring's AOP programming environment builds

1. Create a MAVEN project to configure the jar packages required by spring's AOP
