Kolekcja hibernacji nie jest powiązana z żadną sesją

Question

Znalazłem kilka pytań i odpowiedzi dotyczących tego problemu na SO, ale wszystkie wydają się obejmować jedną główną przyczynę problemu: pobieranie kolekcji poza transakcją lub w ramach innej transakcji . Ale w moim przypadku pobieram w ramach tej samej transakcji podczas pobierania obiektu nadrzędnego i kolekcji.

@Service 
@Transactional 
public class IntegrationServiceImpl implements IntegrationService { 
@Override 
    public Integration getIntegrationByIdFetchBackendParameters(Long integrationId) { 
     Integration integration = integrationDao.get(integrationId); 
     //not all integrations have to have backend. 
     if (integration.getBackend() != null) { 
      Hibernate.initialize(integration.getBackend().getBackendParameters()); 
     } 
     return integration; 
    } 
... 

Ale jeśli chodzi o Hibernate.initialize ten oddział w org.hibernate.collection.internal.AbstractPersistentCollection jest wykonywany

if (session == null) { 
       throw new HibernateException("collection is not associated with any session"); 
      } 

Nie mogę zrozumieć, dlaczego session jest null. Czy ktoś to wytłumaczy i zaproponuje rozwiązanie?

EDIT 1 - Pełna ślad stosu

Answer 1

Wydaje się nazywacie to w swoim sposobie AbstractIntegrationManagedBeaninit.

Musisz się upewnić, że hibernacja zostanie prawidłowo skonfigurowana przed tym punktem.

Najprawdopodobniej twoja konfiguracja tego nie odzwierciedla i zakładasz, że hibernacja już tam jest, chociaż nie ma na to żadnej gwarancji.

Answer 2

Aby zapobiec LazyLoadingException w mojej aplikacji, używam metody pomocnika, że ​​najpierw łączy podmiot z powrotem do sesji, a następnie inicjuje żądanych kolekcji. Ostatnio okazało się, że czasami wciąż cierpi na "kolekcję nie ma związku z żadną sesją", mimo że sesja wydaje się być otwarta i ogólnie wygląda dobrze. Trudno mi powiedzieć, jaka jest przyczyna takiego zachowania, ale mimo to znalazłem lekarstwo przeciwko niemu. Spróbuj odświeżyć stan obiektu przed pobraniem leniwej kolekcji przy użyciu session.refresh(entity). To spowoduje, że Hibernate ponownie załaduje twój obiekt z DB. Po wykonaniu tej czynności bieżąca sesja pozwoli na płynne ładowanie kolekcji za pomocą Hibernate.initialize().

Answer 3

ja też miałem ten problem, jednak problemem dla mnie było to, że nie było konfigurowanie zarządzania transakcyjną w moim pliku konfiguracyjnym tak:

dodać @EnableTransactionManagement Java plik konfiguracyjny lub dodać <tx:annotation-driven/> do xml pliku konfiguracyjnym

Answer 4

Naprawiłem ten problem, umieszczając na wierzchu metody @Transactional.

Answer 5

Rozwiązałem ten problem, umieszczając na wierzchu metody @Transactional. a także uzyskać klasę przez jego id tak:

Test s=get(test.getId()) 

Answer 6

Jak @Zmicier Zaleznicenka wskazał, komunikat ten wyjątek może mieć nic wspólnego z sesją. Wystąpił również ten problem, ale przyczyną źródłową było ustawienie klucza podstawowego jednostki zdefiniowane w pliku odwzorowania było niepoprawne. Na przykład w poniższym kodzie kolumna bazy danych "Foo_SK" nie jest unikalnym identyfikatorem tabeli.

Id(x => x.Id, "Foo_SK").GeneratedBy.Assigned(); 

W naszym przypadku nie mamy kontroli nad schematem bazy danych. W związku z tym naprawiliśmy problem za pomocą mapowania za pomocą klucza złożonego.
