Is there a way to transform objects that spring data repositories return?

Question

Right now I have an entity object and a DTO. The repository returns a list of objects arrays when I do a simple example like: findById(). Is there a way to easily map the re

Answer 1

Try this.

@Query("Select new package.FoodDto(f.id, f.name) from Food f where f.id = :id")
public List findById(@Param("id") String id);

Assuming class FoodDto is in package, if not you need to set the full package.

Also I assume the FoodDto have a constructor that match

public FoodDto(int id, String name){
 //Variable assignation
}

I never tried in spring-jpa but that works in JPQL so I assume it will work XD
