The Spring Data JPA project aims to significantly improve the ORM implementation of data access layers by reducing the effort to the amount that’s actually needed. A developer only needs to write repository interfaces, including custom finder methods, and Spring will provide the implementation automatically.
The following are just a few of the powerful features specific to the Spring Data JPA project:
- Sophisticated support for building repositories based on Spring and JPA
- Support for Querydsl predicates, and thus, type-safe JPA queries
- Transparent auditing of domain classes
- Pagination support, dynamic query execution, and the ability to integrate custom data access code
- Validation of @Query annotated queries at bootstrap time
- Support for XML based entity mapping
- The JavaConfig based repository configuration by introducing @EnableJpaRepositories
