description Spring Data JPA Repository Method Generation Overview
This refactoring technique involves abstracting complex, repetitive database query logic into custom, reusable repository methods. Instead of writing boilerplate CRUD operations for every entity, developers define method signatures (e.g., `findByStatusAndDateBefore`) and let Spring Data JPA generate the underlying SQL implementation. This drastically reduces boilerplate code and centralizes data access logic.
