잡기 하이버 네이트 예외

Question

다음과 같이 나는 @Repository을 가지고 다음과 같이 @Service에 의해 불려

@Repository 
public class OrderRepository { 

    @Autowired 
    SessionFactory sessionFactory; 

    public void update(Order order) { 

     sessionFactory.getCurrentSession().update(order); 
    } 
} 

:

@Transactional 
@Service 
public class OrderService { 

    @Autowired 
    OrderRepository orderRepository; 

    public void updateOrder(Order order) { 

     orderRepository.update(order); 
    } 
} 

업데이트되는 순서가 제거되었습니다 어떤 경우가 있습니다 데이터베이스 (이것은 예상되며 양성이다).

@Repository 
public class OrderRepository { 

    @Autowired 
    SessionFactory sessionFactory; 

    public void update(Order order) { 

     try { 
      sessionFactory.getCurrentSession().update(order); 
     } catch (HibernateOptimisticLockingFailureException e) { 
      System.out.println("Exception occurred"); 
     } 
    } 
} 

는 슬프게도 작동하지 않는 사용자는 여전히 예외를보고 :

내가 저장소 내에서 HibernateOptimisticLockingFailureException을 잡으려고 노력하고 있어요 :이 문제가 발생하면 예외가 발생합니다. 나는 또한 HibernateException과 StaleStateException을 잡으려고 노력했지만 둘 중 어느 것도 그 중 하나도 시도하지 못했습니다.

리포지토리 대신 서비스에 동일한 try/catch를 추가하려고 시도했지만 작동하지 않습니다. 나는 어떤 조언을 주셔서 감사하겠습니다.

Answer 1

실제 업데이트 쿼리는 플러시 시간에 실행됩니다. 세션에서 update()를 호출 할 때가 아닙니다. 이 특별한 경우 플러시는 서비스 메소드에 대한 호출을 처리하는 트랜잭션이 커밋되기 바로 전에 발생합니다. BTW, 그 스택 추적에서 볼 수있다 :

at org.springframework.transaction.interceptor.TransactionAspectSupport.commitTransactionAfterReturning(TransactionAspectSupport.java:478) 

그래서, 당신은 예외를 catch하려는 경우, 당신은 서비스의 외부 그것을 잡을해야합니다

try { 
    orderService.updateOrder(order); 
} 
catch (ConcurrencyFailureException e) { 
    ... 
} 

을 경우에도 명시 적으로 플러시 () 서비스 나 DAO 메소드 내부에서 예외가 발생하면 Hibernate 세션이 신뢰할 수없는 상태로 남을 것이므로 나쁜 생각이 들게된다. 트랜잭션은 롤백되어야하며 세션은 즉시 닫아야합니다. 예외를 버블 링하면 자동으로 처리되기 때문에 서비스를 호출하는 코드에서 catch하는 것이 좋습니다.
