Bonjour, j'ai créé un exemple d'application en utilisant hibernate avec hsqldb.Hibernate n'enregistre aucun enregistrement dans la base de données
Lorsque je lance mon application, cela fonctionne très bien et ne donne aucune erreur, il donne l'accusé de réception suivant pour mes tables. Mais lorsque je vérifie les tables, il n'y a pas d'enregistrements nouvellement entrés.
Voici le code de mon application.
