What is Jakarta Data 1.0 and how does it integrate with Hibernate 7?

import jakarta.data.repository.*;

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

    // Method name derivation:
    List<Product> findByStatus(ProductStatus status);
    List<Product> findByPriceLessThan(BigDecimal maxPrice);
    long countByStatus(ProductStatus status);

    // @Find: type-safe field query
    @Find
    List<Product> findByCategory(
        @By(Product_.CATEGORY) String category,
        @OrderBy(Product_.PRICE) Sort.Direction dir
    );

    // @Query: JPQL
    @Query("FROM Product WHERE status = :status AND price < :maxPrice")
    List<Product> findCheapActive(
        @Param("status") ProductStatus status,
        @Param("maxPrice") BigDecimal maxPrice
    );

    // Key-based pagination:
    Page<Product> findByCategory(String category, PageRequest page);
}

// Usage - inject like any Spring bean:
@Autowired ProductRepository repo;
List<Product> active = repo.findByStatus(ProductStatus.ACTIVE);
