Interface ReviewRepository

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

Provides full CRUD operations inherited from JpaRepository and rich query methods optimized for review management, moderation, and display in the product catalog and customer profiles.

Reviews are user-generated content linking a Customer to a Product with a rating (1–5) and optional text. Efficient access by customer, product, or login is essential for:

  • Displaying reviews on product pages
  • Showing "My Reviews" section in customer profile
  • Admin moderation tools
  • Calculating average product ratings

This repository is automatically implemented by Spring at runtime — no manual implementation required.
