Design for Failures

Comment

The concept of “Design for Failure” is often used to describe the approach that assumes that there will be a hardware or system failure somewhere, sometime – and instead of architecting for hardware and server clustering and availability, to design applications so that recovery can be performed quickly.

@Service
public class RatingServiceImpl implements RatingService {

    @Value("${rating.service.url}")
    private String ratingServiceUrl;

    @Autowired
    private RestTemplate restTemplate;

    @Override
    @Retryable(
            value = {SocketTimeoutException.class},
            maxAttempts = 2,
            backoff = @Backoff(delay = 1000)
    )
    public ProductRatingDTO getRatings(int productId) {
        String url = this.ratingServiceUrl + "/" + productId;
        return this.restTemplate.getForObject(url, ProductRatingDTO.class);
    }

    @Recover
    public ProductRatingDTO getRecoveryRatings() {
        return new ProductRatingDTO();
    }

}
