Interface ProductRepo

All Superinterfaces:
org.springframework.data.repository.CrudRepository<Product,Long>, org.springframework.data.jpa.repository.JpaRepository<Product,Long>, org.springframework.data.repository.ListCrudRepository<Product,Long>, org.springframework.data.repository.ListPagingAndSortingRepository<Product,Long>, org.springframework.data.repository.PagingAndSortingRepository<Product,Long>, org.springframework.data.repository.query.QueryByExampleExecutor<Product>, org.springframework.data.repository.Repository<Product,Long>
public interface ProductRepo extends org.springframework.data.jpa.repository.JpaRepository<Product,Long>
Spring Data repository for Product entities.

Inherits CRUD, pagination, and sorting from JpaRepository and adds a simple case-insensitive name search.

Examples


 // Page through all products, newest first
 Page<Product> page = repo.findAll(PageRequest.of(0, 20, Sort.by(DESC, "id")));

 // Search by name, case-insensitive
 Page<Product> mugs = repo.findByNameContainingIgnoreCase("mug", PageRequest.of(0, 10));

Performance tips:

  • Consider an index on lower(name) for large catalogs to speed up case-insensitive matching.
  • Always pass a Pageable to avoid loading large result sets into memory.
