Bonjour à tous

J'ai cherché sur le forum, malgré cela aucune réponse n'a fonctionné. Je n'arrive pas à lancer mon application car j'ai un message d'erreur, j'ai essayé plusieurs solutions sur le forum mais le problème persiste. Je suis en train de mettre en place ce projet mais je n'ai jamais utilisé ce genre de configuration

 Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
