Bonjour,

Dans le cas d'une refonte d'une application web, je repars uniquement de la base de données (Oracle).
Comment exploiter les classes générées par Hibernate Tools ?

Pour une table Profil par exemple :


Le plugin hibernate Tools me génére deux classes : une pour la primary key et une autre pour les colonnes
Classe Profil.java : qui ne mappe pas correctement les colonnes de ma table.

Code :

Ma question est comment faire une rêquete pour avoir une liste de tous les profils ?

Voici ma fonction qui récupère tous les profils :

Je ne peux pas utiliser le nom Profil dans ma rêquete puisqu'il ne correspond pas a la configuration de ma table .

[tchize_]

La génération a l'air un peu foirax. Je ferais le mapping à la main si j'étais toi.

[yenfou2000]

J'ai beaucoup de tables dans ma base, c'est justement pour ça que je voulais utiliser un outils pour générer les classes.

Tu connais une autre alternative a hibernate Tools ?

[tchize_]

Hibernate fait ce qu'il peut avec les contraintes de la table. Si tu te retrouve avec les 3/4 de la table en clé primaire, il y a un problème sur la table même, aucun outil ne va te sauver.
