Erreur Hibernate lors de l'exécution de DDL via une instruction JDBC
J'ai vraiment besoin d'aide. J'ai cherché dans toutes les questions que j'ai trouvées sur stackoverflow et rien ne fonctionne. Je n'ai jamais utilisé l'hibernation auparavant et je ne sais pas ce que je fais mal.
Voici mon référentiel: https://github.com/ionutincau/test_db
Je reçois cette erreur:

dans votre fichier CFG s'il vous plaît changer le dialecte Hibernate
<!-- SQL dialect -->
<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>
J'ai eu cette erreur en essayant de créer une entité JPA avec le nom "User" (dans Postgres) qui est réservé. La solution consiste donc à changer le nom de la table en annotations @Table:
@Entity
@Table(name="users")
public class User {..}
Ou changez le nom de la table manuellement.
J'ai eu cette même erreur quand j'essayais de faire une table avec le nom "admin". Ensuite, j'ai utilisé l'annotation @Table et donné à la table un nom différent, comme @Table (name = "admins"). Je pense que certains mots sont réservés (comme: - mots-clés en Java) et vous ne pouvez pas les utiliser.
@Entity
@Table(name = "admins")
public class Admin extends TrackedEntity {
}
Je suppose que vous utilisez une ancienne version de Hibernate. Vous pouvez télécharger la dernière version, 5.2, à partir de ici .
La première chose à faire ici est de corriger la version en dialecte de veille prolongée, comme l'a expliqué @JavaLearner. Ensuite, vous devez vous assurer que toutes les versions des dépendances Hibernate que vous utilisez sont à jour. En règle générale, vous avez besoin d'un pilote de base de données tel que mysql-connector-Java, d'une dépendance hibernate: hibernate-core et d'un gestionnaire d'entités hibernate: hibernate-entitymanager. Enfin, n'oubliez pas de vérifier que les tables de la base de données que vous utilisez ne sont pas des mots réservés comme order, group, limit, etc. Cela pourrait vous éviter beaucoup de maux de tête.
Les dialectes sont supprimés dans le SQL récent, utilisez donc
<property name="hibernate.dialect" value="org.hibernate.dialect.MySQL57Dialect"/>
