La collection Hibernate n'est associée à aucune session

J'ai trouvé plusieurs questions et réponses concernant ce problème sur SO, mais elles semblent toutes couvrir une cause majeure du problème: récupérer une collection en dehors d'une transaction ou dans une autre transaction. Mais dans mon cas, je récupère la même transaction lors de la récupération d'un objet parent et d'une collection.

@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;
    }
...

Mais quand il s'agit de Hibernate.initialize cette branche dans org.hibernate.collection.internal.AbstractPersistentCollection est exécutée

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

Je ne vois pas pourquoi session est null. Quelqu'un pourrait-il expliquer cela et suggérer une solution?

J'ai résolu ce problème en mettant simplement @Transactional en haut de la méthode.

Pour éviter un LazyLoadingException dans mon application, j'utilise une méthode d'assistance qui fusionne d'abord l'entité à la session, puis initialise les collections demandées. Il s'est récemment avéré que, parfois, il souffre toujours du problème "la collection n'est associée à aucune session", malgré que la session semble ouverte et semble globalement bien. Il m'est difficile de dire quelle est la cause d'un tel comportement, mais j'ai quand même trouvé un remède contre cela. Essayez d'actualiser l'état de l'entité avant de récupérer la collection paresseuse à l'aide de session.refresh(entity). Cela obligera Hibernate à recharger votre entité à partir de la base de données. Après cela, votre session en cours vous permettra de charger vos collections en douceur avec Hibernate.initialize().

Comme l'a souligné @Zmicier Zaleznicenka, ce message d'exception n'a peut-être rien à voir avec la session. Nous avons également rencontré ce problème, mais la cause principale était que le paramètre de clé primaire d'entité défini dans le fichier de mappage était incorrect. Par exemple, dans le code suivant, la colonne de base de données "Foo_SK" n'est pas l'identifiant unique de la table.

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

Dans notre cas, nous n'avons aucun contrôle sur le schéma de la base de données. Par conséquent, nous avons résolu le problème en utilisant le mappage de clés composites.

Veuillez vérifier l'autre post pour le même problème.

J'ai résolu ce problème en mettant simplement @Transactional en haut de la méthode. Et obtenez également la classe par son identifiant comme ceci:

Test s=get(test.getId())

Moi aussi, j'ai eu ce problème, mais le problème pour moi était que je ne configurais pas la gestion transactionnelle dans mon fichier de configuration:

ajouter @EnableTransactionManagement à Java Fichier de configuration ou ajoutez <tx:annotation-driven/> au fichier de configuration xml

Il semble que vous l'appeliez dans votre méthode init de AbstractIntegrationManagedBean.

Vous devez vous assurer que la mise en veille prolongée est correctement configurée avant ce point.

Votre configuration ne reflète probablement pas cela et vous supposez que l'hibernation est déjà là, bien qu'il n'y ait aucune garantie pour cela.

Voir cette question pour plus de détails: Comment contrôler l'ordre d'invocation de la méthode d'initialisation du bean dans Spring?
