Spring Data JPA Repository Creator

Instructions

The following are key principles to follow while creating Spring Data JPA Repositories:

• Make sure to create the recommended package structure for Spring Boot projects
• Create repositories only for aggregate roots
• Use @Query with JPQL for custom queries
• Prefer meaningful method names over long Spring Data JPA finder methods
• Use constructor expressions or Projections for read operations
• Use default methods for convenience operations

Example: EventRepository

File: events/domain/EventRepository.java

interface EventRepository extends JpaRepository<EventEntity, EventId> {
