J'essaie d'obtenir EclipseLink pour fonctionner avec Spring (MVC et Spring-Data) version 3.1.1 et je suis à un problème dès le début . L'erreur ci-dessous se produit au démarrage de Tomcat (v7.0). J'ai cherché l'erreur mais je n'ai pas trouvé grand-chose et je ne sais pas trop où aller. On parle de ce problème lors de l'utilisation d'interfaces avec des classes Entity, mais comme vous pouvez le voir, ma classe User.java ne s'étend à rien.Erreur EclipseLink: La classe d'entité n'a pas de clé primaire spécifiée. Il devrait définir soit un @Id, @EmbeddedId ou un @IdClass
