How does Spring support Aspect-Oriented Programming (AOP)?

Spring provides support for Aspect-Oriented Programming (AOP) through its robust AOP framework. AOP allows developers to modularize cross-cutting concerns, such as logging, security, and transaction management, into reusable components called aspects.

Spring simplifies AOP implementation by using AOP proxies that intercept method invocations and apply advice (logic) before, after, or around the actual methods. This allows developers to separate core business logic from cross-cutting concerns, improving code maintainability and reusability.

Key components of Spring's AOP support include pointcuts (where advice should be applied), advice (actual logic to be executed), and aspects (combination of pointcuts and advice). Developers can also leverage annotations or XML configuration to define aspects and apply them to specific methods or classes.

Overall, Spring's AOP support enhances modularity, improves code quality, and promotes cleaner application design by decoupling cross-cutting concerns from business logic.
