Hibernate + Spring

Bonjour,
après avoir suivi un tuto sur internet pour intégrer Spring à mon application web. cela ne fonction toujours pas

Ma classe Dao, ne récupère pas l'entityManager qui aurait du être instancié par Spring. J'ai cherché toute l'apres midi et je ne trouve pas. J'ai surement oublié quelque chose mais la je vois pas.

donc voici des détails

applicationContext.xml (fichier de configuration de Spring)
