JPA @Query java.lang.IllegalArgumentException:

Have problem with this code

public interface CharityRepository extends CrudRepository<Charity,Long> {

  @Query("select sum(sponsorSum) from Charity")
  Integer totalCharitySum();
}

Throw exception

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'adminController' defined in file [D:\IdeaProjects\maraphonskills(3)\target\classes\com\maraphon\maraphonskills\controllers\AdminController.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'charityServiceImpl' defined in file [D:\IdeaProjects\maraphonskills(3)\target\classes\com\maraphon\maraphonskills\service\CharityServiceImpl.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'charityRepository': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: Validation failed for query for method public abstract java.lang.Short com.maraphon.maraphonskills.repository.CharityRepository.totalCharitySum()!

But this code works fine

public interface CharityRepository extends CrudRepository<Charity,Long> {
  @Query("select sum(sponsorTarget) from Registration")
  Short totalSum();
}

@Modifying doesn't help.What could be the problem?
