Mapper un Map sous Hibernate
Bonjour,
Je suis sur hibernate depuis un moment pour une appli. Avant j'utilisais un Set<Competence>, mais je dois passer à un Map<Competence,Integer>.
J'ai regardé sur pas mal de sites, mais les réponses ne corrigent pas l'erreur.
Voici l'exception levée :
Edit : avec le code c'est mieux...
Code:
1

|
@ElementCollection(targetClass=Competence.class,fetch=FetchType.EAGER)
@MapKey(name="id")
@ManyToMany(targetEntity = Competence.class, cascade = {
CascadeType.PERSIST, CascadeType.MERGE })
private Map<Competence,Integer> competences = new HashMap<Competence,Integer>(); |
Code:

Pourriez-vous m'expliquer d'où elle vient? Étant novice en hibernate, je pense qu'il cherche à créer une clé pour l'Integer mais j'en suis pas sur...
Je vous remercie par avance pour vos réponses.
