I have classes Category and SubCategory. Now in SubCategoryRepository, I have written a method something like - 

@Repository
public interface SubCategoryRepository extends JpaRepository<SubCategory, Long> {

    List<SubCategory> findByCategoryName(String categoryName);
}

How will this implementation work internally? How will it find based on category name. Category class is having field as - 

class Category {
    private String categoryName;
}
