Spring AOP

Spring AOP (Aspect-Oriented Programming) is a way to add common functionalities—like logging, security checks, or transaction management—to your application without cluttering the core logic. It separates these concerns into special modules called "aspects" that automatically execute at designated points in your program's flow, called "join points." This modular approach makes the code cleaner, more maintainable, and easier to manage. Essentially, Spring AOP helps you inject additional behavior into existing code seamlessly, like adding borders or decorators to a product without altering its core design.
