Spring_AOP	Aspect Join Point Advice - Before, After, After Returning, After Throwing, Around Pointcut Introduction Weaving
Configuration	XML-based Configuration Annotation-based Configuration
Proxies	Spring AOP uses proxies to implement aspects. JDK Dynamic Proxies: Used if the target object implements at least one interface. CGLIB Proxies: Used if the target object does not implement any interfaces.
Common annotations	@Aspect: Marks a class as an aspect. @Before: Marks a method as a before advice. @After: Marks a method as an after advice. @AfterReturning: Marks a method as an after returning advice. @AfterThrowing: Marks a method as an after throwing advice. @Around: Marks a method as an around advice. @Pointcut: Declares a reusable pointcut expression. @DeclareParents: Used for introduction, allowing an aspect to declare that a type implements a new interface. @EnableAspectJAutoProxy: Enables support for handling components marked with AspectJ's @Aspect annotation. It can be added to a Java configuration class.
Declarative vs Programmatic AOP	Declarative AOP: Configuring aspects using XML or annotations. Programmatic AOP: Manually creating proxies and applying aspects in code.
Load-Time Weaving (LTW):	Enables aspects to be woven into classes during class loading rather than at compile time or runtime. Useful for scenarios where runtime proxies are not sufficient.
