如何编写Spring Data JPA查询在group by之后获取两个计数

@Repository
public interface UserRepository extends JpaRepository<User, Long> {
    @Query("SELECT u.gender, COUNT(u) as count1, COUNT(DISTINCT u.age) as count2 FROM User u GROUP BY u.gender")
    List<Object[]> countByGender();
}

@Service
public class UserService {
    @Autowired
    private UserRepository userRepository;

    public void countByGender() {
        List<Object[]> result = userRepository.countByGender();
        for (Object[] row : result) {
            String gender = (String) row[0];
            Long count1 = (Long) row[1];
            Long count2 = (Long) row[2];
            System.out.println("Gender: " + gender + ", Count1: " + count1 + ", Count2: " + count2);
        }
    }
}
