Spring et hibernate

**zaidoune** · 10/03/2010, 12h20

salut ,
Je travaille sur un projet qui utilise les technologie Spring, Hibernate, Spring MVC. j`ai un probleme au niveau de hibernate .La (P.J) decrit une partie de ma conception de la base de donnees . J`aime avoir une requête qui m`aide a extraire les données qui existe dans la table "employes_has_rules" sachant que la table "Employes" et " rules " possèdent entre eux une relation "manytomany", mais j`arrive pas a le faire . j`ai fait des methodes getter et setter d`une collection mais toujours le problème persiste .
voici l`entité Employes
