带有JPA的@Retryable会产生问题

关注this post我正在尝试使用@Retryable实现我的Invoice bean的save（）方法，以使我的应用程序更加可靠。 我正在使用Spring JPA + Hibernate。

我为我的服务提供了接口：

@RemoteDestination
@DataEnabled
 @PreAuthorize("hasAnyRole('AMMINISTRATORE','CAPO_SERVIZIO','UTENTE','CONTABILITA')")
public interface FatturaCustomRepository {

@Retryable(backoff = @Backoff(delay = 200, multiplier = 2, random = true), maxAttempts = 5)
public <S extends Fattura> S save(S invoice) throws Exception;
}

这是实施：

@Override
@Transactional
public <S extends Fattura> S save(S invoice) throws Exception {
    log.debug("public <S extends Fattura> S salva(S fattura, List<Long> idVendite)");

        int anno = LocalDate.now().getYear();           
        String sQuery = "SELECT MAX(numero) FROM Fattura WHERE YEAR(data) = :anno ";
        Query q = manager.createQuery(sQuery);
        q.setParameter("anno", anno);
        Integer maxNum = 0;
        try {
            maxNum = (Integer) q.getSingleResult();
            log.debug("Numero trovato: " + maxNum);
            if (maxNum == null)
                maxNum = 0;
        } catch (NoResultException e) {             
            maxNum = 0;
        } catch (Exception e) {             
            maxNum = 0;
        }
        int numeroFattura = maxNum + 1 ;            
        invoice.setNumero(numeroFattura);       


         if (fattura.isNew())
             manager.persist(invoice);
         else
             manager.merge(invoice);

        return invoice;
    }
}

模拟错误（重复的财务编号）我在日志中看到Spring尝试重做事务，但Hibernate会话似乎有问题。

Spring重试不应该对应用程序的其余部分透明吗？代码中的问题在哪里？

由于

1 个答案:

答案 0 :(得分：0)

我解决了添加

的问题 
entityManager.clear();

位于方法的顶部

public <S extends Fattura> S save(S invoice)

不确定这是最好的方法，但我找不到其他任何有用的方法来解决这个问题！
