What capabilities does aspect-oriented programming provide within Spring AOP?

Aspect-Oriented Programming (AOP) in Spring allows separating cross-cutting concerns (such as logging, security, transactions) from business logic, enhancing code modularity.

Spring AOP features:

• Defining aspects — classes containing cross-cutting logic.
• Advice — code that executes at specific points (before, after, around method calls).
• Pointcuts — expressions that determine which methods advice applies to.
• Declarative transaction management through aspects.

Example of using Spring AOP for logging method calls:

@Aspect
@Component
public class LoggingAspect {
    @Before("execution(* com.example.service.*.*(..))")
    public void logBefore(JoinPoint joinPoint) {
        System.out.println("Method call: " + joinPoint.getSignature().getName());
    }
}

Thus, AOP helps centrally manage repetitive tasks without polluting business logic.
