[Zenith]

Bonjour,

Je travaille sur un projet de portlet avec Spring MVC 3 et Hibernate, et je suis confronté à un probleme que je ne parviens pas à résoudre.

J'ai des tables reliées entre elles via de multiples associations ManyToOne et OneToMany.

Mon probleme est que je souhaite accéder à des champs des objets représentant ces tables via lazy loading dans la vue de mon portlet. Jusque la, pour éviter la fameuse LazyInitializationException, je force le chargement de mes objets a base de requetes supplémentaires (du eager loading barbarre quoi ....) C'est pas beau, je sais.

Pour éviter cela, je pense qu'il faut que j'étende la durée de vie de ma session Hibernate à toute la durée de traitement de ma requete, pour pouvoir conserver l'avantage du lazy loading dans la vue

C'est la que ca coince. Je n'arrive pas à mettre en place le pattern OSIV (OpenSessionInView) dont tout le monde parle sur le net, et j'ai besoin d'un coup de main à ce niveau la.

Je vous poste quelques segments de code ou j'ai peut etre fait n'importe quoi:

Merci d'avance de votre aide.

Je précise que je fais bel et bien des recherches pour résoudre mon problème, sans pour autant y arriver.

D'apres ce que j'ai compri, OSIV ne peut être mis en place dans les portlets de la meme facon qu'il l'est dans les servlets à cause du découpage du traitement des requetes dans un portlet (action/render).

any suggestions ?

dans ton fichier web.xml ajouter ça:

Salut,

Merci de ta réponse,

J'avais déjà essayé de mettre un filtre, ca a effectivement changé une partie du probleme, mais pas tout. Je m'explique:

J'ai moins d'exceptions LazyInitializationException (j'en ai toujours cependant), mais la jsp ne parvient pas à trouver les données. Par exemple, j'arrive à afficher les informations sur un Group récupéré en BD, mais pas celles des Content de chaque Publication de ce Group (Group -> List<Publication> -> List<Content>), c'est comme si la jsp recevait des valeurs vides.

un autre probleme est que lorsque, dans ma couche service, je fais par exemple: group.getPublications().add(publication); je me retrouve avec une LazyInitializationException, dont voici la trace:

Code de la fonction ou se trouve la ligne (classe PublicationService):

	}

[Jacobian]

annoter la méthode addPublication @Transactional

[Zenith]

annoter la méthode addPublication @Transactional

Mes services sont déjà annotés en @Transactional au niveau de la classe

[Jacobian]

si ta met le filter dans web.xml et tu a annoté la méthode ça devrais marcher parce que l'annotation laisse la session ouverte si ta une autre exception met le ici

[Zenith]

Voici l'exception que ca me donne (j'ai mi le XML que tu m'as donné dans web.xml, et mes services sont marqués Transactionnal):
