Et voici le code de ma classe TClient:

et voici l'appel que je fais dans ma fonction main()

        // couche service
            service = (IService) ctx.getBean("service");
                service.getAll();

Et maintenant quand j'exécute mon programme le message d'erreur suivant:

J'ai vraiment besoin de comprendre comment faire le mapping Spring dans le fichier de configuration.

Merci d'avance!
