Jakarta Data 1.0

Release for Jakarta EE 11

The Jakarta Data specification provides an API for easier data access. A Java developer can split the persistence from the model with several features, such as the ability to compose custom query methods on a Repository interface.

Jakarta Data’s goal is to provide a familiar and consistent, Jakarta-based programming model for data access while still retaining the particular traits of the underlying data store.

Goals

  • Increase productivity performing common database operations
  • Rich Object Mapping integrated
  • Define Repositories
@Repository
public interface Garage extends BasicRepository<Car, Long> {

  List<Car> findByType(CarType type);

  Optional<Car> findByName(String name);

}
...

@Inject
Garage garage;
...
Car ferrari = Car.id(10L).name("Ferrari").type(CarType.SPORT);
garage.save(ferrari);

New features, enhancements or additions

  • Define the Repository pattern
  • Allows pagination on Repository
  • Enhance type safety with a StaticMetamodel
  • Define platform integrations with CDI, Persistence, NoSQL, Transactions, and Validation
  • Produce a TCK with the ability to run against the following matrix:
    • Profiles: none (standalone), core, web, platform
    • Entities: persistence, nosql

Removals, deprecations or backwards incompatible changes
