Generical CrudRepository unrelated Entities, Native Queries multible Entities












0














I know how use CrudRepository related to some entity...



import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.data.repository.CrudRepository;

public interface MyEntityRepository extends CrudRepository<MyEntity, Long>, JpaRepository<MyEntity, Long> {

//MyCustom Queries

}


But, I need to use Queries unrelated to specific Entity (There is not exist specific Entity, and I have multiple Queries of these types)
I want to put all kind of these queries in only one class.



Here my code something like...



import java.util.List;
import org.springframework.data.jpa.repository.Query;

public class MyGeneralRepository {

static final String QUERY_findCompoundResult
= "SELECT ta.param1, tb.param2 "
+ "FROM myscheme.tablea ta, myscheme.tableb tb "
+ "WHERE ta.param2 = tb.param2 ";
@Query(value = QUERY_findCompoundResult, nativeQuery = true)
List<Object> findCompoundResult();
}


Now in my IDE I have: missing method body, or declare abstract obviously because I haven't implemented method.



Then my Questions:




  1. How explode the CrudRepository potential without relate someone Entity?


  2. Is it possible?
