java - Spring JPA没有从数据库中获取最新记录

Question

我有一个用用户的参考号更新数据库的方法，然后我有一个 Spring 重试机制来重试并检查用户的记录是否用参考号更新。但是重试调用不会从数据库中获取最新记录。我没有更新记录的问题，但只有获取，它没有获取最新的更新记录。

用户重试模板

@Component
public class UserRetryTemplate {


    @Value("${retry.max.attempts:5}")
    private int maxAttempts;

    @Value("${response.waiting.time.in.seconds:60}")
    private long maxDelay;

    @Autowired
    private UserRepository userRepository;

    private static final long INITIAL_INTERVAL = 2000L;

    public RetryTemplate retryTemplate() {

        // Max timeout in milliseconds
        long maxTimeout = maxDelay*1000;

        //double multiplier = (maxTimeout - INITIAL_INTERVAL)/((maxAttempts-2)*6000);

        SimpleRetryPolicy retryPolicy = new SimpleRetryPolicy();
        retryPolicy.setMaxAttempts(maxAttempts);


        FixedBackOffPolicy backOffPolicy = new FixedBackOffPolicy();
        backOffPolicy.setBackOffPeriod(maxTimeout/(maxAttempts-1));

        RetryTemplate template = new RetryTemplate();
        template.setRetryPolicy(retryPolicy);
        template.setBackOffPolicy(backOffPolicy);
        return template;
    }

    public boolean doUserReferenceRetry(String userId) {
        boolean isUserReferenceValid = true;
        try {
            boolean isValidUser = retryTemplate().execute(context -> {
                logger.info("Attempted {} times", context.getRetryCount());
                User user = userRepository.findByUserName(userId);
                logger.info("User Retry :" + user);

                if (user.getResponseDateItem() == null || user.getReferenceNumber == null) {
                    logger.info("response not yet received");
                    throw new IllegalStateException("User Response not yet received");
                }
                if (user.getReferenceNumber != null)) {
                    return true;
                }
                throw new IllegalStateException("Response not yet received");
            });
            return isUserReferenceValid ;
        } catch (IllegalArgumentException e) {

        }
        return true;
    }

}

用户存储库.java

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

    User findByUserName(String userName);

}

UserManagerImpl

public void updateReference(String userId, String referenceNumber) {

        User user = userRepository.findById(userId);
        if (user != null) {
            user.setReference(referenceNumber);
            user.setResponseDate(DateHelper.createXMLGregorianCalendar());
            userRepository.saveAndFlush(user);
        }
    }

队列在处理响应时更新数据库中用户的参考编号（工作正常）

用户队列客户端：

@Component
public class UserQueueClient {



    @JmsListener(id = "#{T(java.util.UUID).nameUUIDFromBytes('${in.res}",
            destination = "${in.res}", containerFactory = "containerFactory")
    public void receive(Message message, UserEnvelopeV1_0 envelope) throws{


        try {
            String userId = envelope.getHeader().getMessageIdentification().getUserId();
 ApplicationInformationStructure applicationInformation = envelope.getBody().getApplicationInformation();

if(CollectionUtils.isNotEmpty(applicationInformation.getApplicationInformationResult())) {
          String referenceNumber = applicationInformation.getApplicationInformationResult().getRefNumber();      

                userManager.updateReference(userId, referenceNumber);
            }

        } catch (Exception e) {
            //
        }
    }


}

所以还有其他更新参考号的过程，它工作正常，它用值更新数据库。但是读取（来自重试模板）不会获取更新的记录。
