Clé composite : souci mapping

**VanFanel** · 27/07/2010, 11h34

Hello,

Je débute sur Hibernate, et le projet a un schéma de base complexe

Env.
Base Mysql
Développement sous Eclipse avec Spring, Hibernate

J'ai l'erreur suivante : FATAL (ThesaurusTreeDaoImpl.java:64) Erreur lors du chargement du site 1
java.lang.IllegalArgumentException: org.hibernate.hql.ast.QuerySyntaxException: ThesaurusTree is not mapped [SELECT tt FROM ThesaurusTree tt WHERE tt.id.site.id = :siteId]

Auriez vous une petite idée de la cause ?? Merci par avance.

Arff, il suffisait que je rajoute dans persistence_tree.xml

<class>com.leguide.thesaurus.tree.model.Site</class>
<class>com.leguide.thesaurus.tree.model.Thesaurus</class>
<class>com.leguide.thesaurus.tree.model.ThesaurusTree</class>

Dans JUnit Test, il ne prenait pas en compte les classes ci-dessus.
