Calculation service with transaction and retry logic

Conducting a code review of a method that retrieves data, calculates a financial indicator, saves it to a repository, and sends a notification. The method is implemented within a transaction and contains a retry loop for data retrieval.

@Component
public class CalculateService {

    @Autowired
    private FileInfoService fileInfoService;

    @Autowired
    private SaveRepository saveRepository;

    @Autowired
    private Notification notification;

    private static final int MAX_ATTEMPTS = 3;

    @Transactional
    public void calculation(GetFilesInfoRequest request) {
        int attempts = 0;
        double totalCount = 0;
        double divisor = 6.85;
        double commissionRate = 5.2534;

        while (attempts < MAX_ATTEMPTS) {
            SendForNotify fileInfo = fileInfoService.getFilesInfo(request);
            if (fileInfo != null) {
                totalCount = fileInfo.getCount();
                break;
            }
            attempts++;
        }

        double result = (totalCount * commissionRate) / divisor;
        saveRepository.save(result);

        try {
            notification.sendCalculate(result);
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}
