| What is Spring AOP? |
- Spring AOP
- There is a need for a separate compilation process.
- It supports only method execution pointcuts.
- It can be implemented on beans managed by Spring Container.
- It supports only method level weaving.
- Aspect - A code unit that encapsulates pointcuts, advices, and attributes.
- PointCut - It defines the set of entry points in which advice is executed.
- Weaving - It constructs code (source or object) with advice.
- JDK & CGLib proxy
- Introduction - It allows you to add new methods or attributes to existing classes.
- Advice - It is an implementation of cross-cutting concerns.
- Before Advice: An advice that executes before a join point, is called before advice. We use @Before annotation to mark an advice as Before advice.
- After Advice: An advice that executes after a join point, is called after advice. We use @After annotation to mark an advice as After advice.
- Around Advice: An advice that executes before and after of a join point, is called around advice.
- After Throwing Advice: An advice that executes when a join point throws an exception.
- After Returning Advice: An advice that executes when a method executes successfully.
- Cross cutting concern - It is a concern that we want to implement in multiple places in an application. It affects the entire application.
- Join point - This represents a point in your application where you can plug-in AOP aspect. It is the actual place in the application where an action will be taken using Spring AOP framework.
- Target object - The object being advised by one or more aspects. This object will always be a proxied object. Also referred to as the advised object.
- AOP Alliance
Difference
- Spring AOP and aspectJ
- Concern and cross-cutting concern
