`Type cannot be null` exception when trying to run out Stored Procedure using Spring Data JPA

Question

I am trying to invoke a Stored Procedure whose signature looks like the following:

CREATE OR REPLACE PROCEDURE FIND_FIRST_BOOKMARK_GT(bookmark IN NUMBER, cur OUT         


        

Answer 1

Faced with the same issue using @Procedure. As a workaround, you could refer to the entityManager in the service class and call procedure from it.

@Service
public interface ResponseService {

    @PersistenceContext
    EntityManager entityManager;

    public Response findFirstBookmarkGreaterThan(Long bookmark){
          Query query  = entityManager.createNamedStoredProcedureQuery("Response.findFirstBookmarkGreaterThan");
          query.setParameter("bookmark", bookmark);
          return query.getFirstResult();
    };
}

Note that Response must be an @Entity.
