Génération de schéma avec Maven Hibernate3 plugin
Je suis en train de configurer un simple hibernate + projet maven. Je suis en suivant les étapes comme mentionné dans le Chapitre 2 de Java presistence avec hibernate (seule diff c'est que je suis à l'aide de maven au lieu de Fourmi). Cependant, tout en essayant de générer le schéma avec maven, hibernate 3 plugin, il semble qu'il n'est pas en mesure de créer les tables nécessaires.

</hibernate-configuration>- juste pour être sûr, vous voulez générer le schéma sur la DB ou pour générer le schéma DDL?
- Je le voulais pour générer un schéma sur la DB. Et aussi, le fichier de sortie
F:\workspace\SpringExample\target\hibernate3\sql\schema.sqlest également vide.
Vous devez vous connecter pour publier un commentaire.
Je pense que le problème avec la la DDL création, c'est qu'il ne peut pas trouver le fichier de configuration hibernate. Essayez d'enlever le slash sur le chemin d'accès dans le fichier pom. De sorte que la ligne devrait se lire comme suit:
Pour créer automatiquement la DB ajouter la propriété suivante à votre hiberante.cfg.xml
hibernate.cfg.xml
