Aspect-Oriented Programming entails breaking down program logic into distinct parts called so-called concerns. … Spring AOP module provides interceptors to intercept an application. For example, when a method is executed, you can add extra functionality before or after the method execution.

Is AOP still used?

Nowadays I see some AOP still around, but it seems to have faded into the background. Even Gregor Kiczales (inventor of AOP) called it a 15% solution. So I guess AOP has its reason for existence, but it depends on the individual developer to use it the right way.

What are the benefits of AOP?

You can use AOP to reduce code clutter by improving the readability and maintainability of your code. It should be noted that AOP is just a new programming paradigm — it doesn’t replace OOP in any way. Rather, it complements OOP by providing you another way to achieve modularity and also reduce code clutter.
