This is a pair programming test that uses Spring Cloud Open Feign to call an external validator.
I failed this test because I didn't know that Spring AOP wouldn't work if @Retryable method and calling method were in the same class.
The problem is explained at Understanding AOP Proxies.
The solution is simply extracting the AOP-annotated methods into a separate class.
@Component
@RequiredArgsConstructor
@Slf4j
public class PersonValidator {
private final ValidatorClient validatorClient;
@Retryable(value = RuntimeException.class, backoff = @Backoff(5000))
public String validatePhoneNumberDigits(String phoneNumber) {
log.info("Calling #validatePhoneNumberDigits...");
String response = validatorClient.validatePhoneNumberDigits(phoneNumber);
log.info("#validatePhoneNumberDigits; " + response);
return response;
}
}
