Spring Data JPA (Boot 4 / Hibernate 7)

Spring Boot 4 manages Jakarta Persistence 3.2, Jakarta Validation 3.1, and Hibernate ORM 7.x. Use Boot dependency management and import jakarta.persistence.* / jakarta.validation.*. Do not add explicit Hibernate, JPA, or Validator versions unless the project has a deliberate override policy.

Entity Model Rules

Use an @Entity only for persistent state with identity and lifecycle. Use records for DTOs, commands, and read models. Use @Embeddable for values stored inside an entity table.
