[hibernate Tools][LazyInitializationException] Au secour (many-to-many)

ça ne marche pas !!! je comprends plus....
(vraiment, aidez moi ou je vais tout peter)

l'enregistrement dans la table de liaison ne ce fait jamais ! j'ai ajouter les hashcode mais ca ma fait l'erreur sur les hashcode propriete.hashcode() qui est un Set.

3 tables :
films
propriete
film_has propriete

2 objets:
films
propriete

2 mappings :

Merci (infiniment)

Code:

1 2 3 4 Set test=proprieteses; int testhc=test.hashCode(); <------ apparement l'erreur viendrais d'ici ! result = PRIME * result + ((proprieteses == null)....
Est-ce que redefinir les methode hashcode et equal est vraiment nécessaire ?

avec j'ai l'exception LazyInitializationException

et sans je n'ai pas d'enregistrement

Code:

Set p=f.getProprieteses();

quand tu fais ça tu tente de charger les proprietes de film.
tu as bien chargé ta classe film.
mais par defaut dans hibernate les set ne sont pas chargés (lazy loading, chargement paresseux, ie lazy="true");
une solution simple pour charger tout les set à chaque fois que tu charges un film, ajouter lazy="false dans le mapping :
Code:

1 2 3 4 5 6 7 8 9 10 11 12 <set name="proprieteses" inverse="true" table="films_has_proprietes" lazy="false"> <key> <column name="films_idfilms" not-null="true"> <comment></comment> </column> </key> <many-to-many entity-name="com.db.hibernate.Proprietes"> <column name="proprietes_idproprietes" not-null="true"> <comment></comment> </column> </many-to-many> </set>
sinon si tu veux charger ces proprietes au cas par cas (et pas chaque fois que tu recupere un film) , tu mets lazy=true dans le set (ou rien puisque c la valeur par defaut).
et tu provoques le chargement des proprietes :
requete = "from film f left join fetch f.proprietes";

Bein je comprends pas bien le rapport car mais propriete sont bien charge puisque je les affiche dans la boucle , mais c'est la mise a jour (donc en fait l'enregistrement dans la table de liaison ) qui ne ce fait pas .

pas une autre idée ???

Ha pardon.
Hibernate n'enregistre les enfants de ton objet parents que si tu "cascade".
Code:

1 2 3 4 5 6 7 8 9 10 11 12 <set name="proprieteses" inverse="true" table="films_has_proprietes" lazy="false" cascade="save-update"> <key> <column name="films_idfilms" not-null="true"> <comment></comment> </column> </key> <many-to-many entity-name="com.db.hibernate.Proprietes"> <column name="proprietes_idproprietes" not-null="true"> <comment></comment> </column> </many-to-many> </set>
pour les effacer si tu effaces le parent il faut un cascade="delete"
et pour les 2 : cascade="all"
ou plus radical "all-delete-orphan"

plus d'info sur cascade dans la doc
