Using Spring Aspect in Spring Boot

 Spring Aspect (AOP) aims to help with separation of concerns by providing clean reusable annotation classes.

When we work with REST controllers, especially when we create APIs for internal (or external) use, we usually end up with a lot of duplicate code that is difficult to refactor out. To solve this we will utilize Spring Aspect and Aspect-Oriented Programming (AOP) in a real world example of how you may completely remove duplicate code in your REST Controllers.
