Have you worked with Spring AOP? What task did you solve using custom aspects?

Spring AOP (Aspect-Oriented Programming) allows separation of cross-cutting concerns (such as logging, transactions, security) from business logic. In projects with Spring AOP, custom aspects are often created to address tasks such as:

• Logging method calls with parameters and execution time.
• Managing transactions in non-standard scenarios.
• Validating input data before method execution.
• Caching method results.

For example, I created an aspect for logging all service method calls with the method name and execution time, which helped quickly identify performance bottlenecks without changing business logic.
