Spring Data JPA

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
