Have you had experience applying aspect-oriented programming in your projects?

Yes, I have experience applying aspect-oriented programming (AOP). In Java projects, I used AOP to implement cross-cutting concerns such as logging, transaction management, and access control, without cluttering the business logic. For example, with Spring AOP, you can define an aspect that automatically logs 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());
    }
}

This allows separating auxiliary code from the main logic and increases the modularity of the application.
