Table of Contents

Introduction

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.

Repository

A repository abstraction aims to significantly reduce the boilerplate code required to implement data access layers for various persistence stores.

@Repository
public interface CarRepository extends CrudRepository<Car, Long> {

  List<Car> findByType(CarType type);

  Optional<Car> findByName(String name);

}
@Inject
CarRepository repository;
...
Car ferrari = Car.id(10L).name("Ferrari").type(CarType.SPORT);
repository.save(ferrari);

Pagination

Jakarta Data also supports particular parameters to define pagination and sorting.

@Repository
public interface ProductRepository extends PageableRepository<Product, Long> {

 Page<Car> findByTypeOrderByName(CarType type, Pageable pageable);

}
