Alors, quelqu'un peut-il m'aider à faire fonctionner correctement l'em.
Merci Mohammed Amr.
Réponses:
1 pour la réponse № 1Ceci est un problème de chargeur de classe, vous avez en quelque sorte deux versions différentes de la même classe chargées.
Assurez-vous de ne pas avoir déployé cette classe à deux endroits différents et d'avoir correctement configuré Spring. Peut-être essayer quelques exemples de printemps.
Êtes-vous redéployé? Si vous n'avez pas fermé l'ancien EntityManagerFactory, vous pouvez obtenir cette erreur. Essayez de redémarrer le serveur.
Toutes vos classes ont-elles la même erreur ou travaillez-vous?
1 pour la réponse № 2
J'ai compris :),
Parce que j'utilise tomcat 7 pour les applications en cours d'exécution, et qu'il ne s'agit pas d'un EE, il doit donc utiliser "LocalEntityManagerFactory" plutôt que "LocalContainerEntityManagerFactory".
De cette manière, vous pourrez invoquer les méthodes du gestionnaire d’entités et prendre une transaction dans votre compte.

Peut-être que vous devez spécifiquement GénérerType, pas utiliser GenerationType.Auto.Essayez.Je ne suis pas sûr.Le même cas est ici
