如何在Entity的瞬态字段中设置来自存储过程的计算字段？

@Entity
@Table(name = "user")
public class User {

    @Id
    private Long id;

    private String name;
    
    @Transient
    private String calculatedField; // 瞬态字段用于存储计算结果
    
    // 省略其他字段和方法
}

@Repository
public interface UserRepository extends JpaRepository<User, Long> {

    @Query(value = "CALL calculate_field(:userId)", nativeQuery = true)
    void setCalculatedField(@Param("userId") Long userId);
}

@Service
public class UserService {

    @Autowired
    private UserRepository userRepository;

    public void calculateAndSetField(Long userId) {
        userRepository.setCalculatedField(userId);
    }
    
    // 省略其他服务方法和业务逻辑
}
