What is Spring AOP and how does it work?

Spring AOP (Aspect-Oriented Programming) is a programming paradigm that allows you to separate cross-cutting concerns from your business logic. It enables you to define aspects, which are reusable modules that can be applied to various parts of your application.

Can you give me an example of how to implement AOP in a Spring application?

Sure! You can create an aspect by using the @Aspect annotation. For example, you can log method execution times by defining a pointcut and an advice that runs before or after the method execution.

What are some common use cases for Spring AOP?

Common use cases include logging, transaction management, security, and performance monitoring. AOP helps keep these concerns separate from your core business logic.

How does AOP differ from traditional OOP?

AOP focuses on cross-cutting concerns that affect multiple parts of an application, while OOP is centered around objects and their interactions. AOP allows for cleaner code by separating these concerns.
