org.hibernate.tool.schema.spi.CommandAcceptanceException: erreur lors de l'exécution du DDL via l'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. J'ai généré des tableaux mais avec des insertions, j'ai des problèmes. 

Je reçois cette erreur:

problème dans votre changement de moteur de dialecte à votre dialecte mysql ajouter les lignes suivantes

J'ai eu cette exception avec SprintBoot 2.x, en changeant le dialecte, il a été résolu. Org.hibernate.tool.schema.spi.CommandAcceptanceException: Erreur lors de l'exécution du DDL via l'instruction JDBC

Je faisais face au même problème et ce qui me fait ressortir de cette exception a été illustré dans les étapes suivantes:

  1. Modification de la balise <hibernate-configuration name=""> en <hibernate-configuration> dans le fichier hibernate.cfg.xml.
  2. Mentionnez toujours la balise de connexion avec l’hôte localhost, le port et le nom du schéma ou de la base de données, par exemple - <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/protein_tracker</property>

et cela rend l'exécution sans exception, cela fonctionne pour moi, j'espère que cela vous aidera aussi un peu!

Pour être précis, votre pilote Hibernate JDBC a un problème lors de l'exécution d'un script (DDL) vers la base de données mysql. 

Dans l'erreur, il y a une explication appropriée: Il y a une exception sur la requête SQL avec l'erreur "Impossible d'ajouter une contrainte de clé étrangère".

Vous avez plusieurs tables mappées, donc je suggère d'aller une par une et de voir quelle génération de table a l'erreur. Cela vous guidera pour comprendre l’erreur de contrainte que vous avez.

Le journal des erreurs que vous avez fourni n'est pas pertinent car il indique les erreurs des tables statistiques qui sont remplacées par d'autres statistiques pour l'exécution du moteur de base de données.

Merci
