GenerationTarget a rencontré une exception lors de l'acceptation de la commande: erreur lors de l'exécution du DDL via l'instruction JDBC

Je suis novice dans le monde en hibernation et en face,

WARN: GenerationTarget encountered exception accepting command : Error executing DDL via JDBC Statement
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement

exception pendant que je lance mon programme autonome dans la version 5.2.9 d'Hibernate. Mais en version Hibernate 4, tout mon code fonctionne bien. Je cherchais beaucoup de questions et je résolvais mais je ne travaillais pas.

Vous devriez essayer différents dialectes tels queorg.hibernate.dialect.MySQL5Dialect OR org.hibernate.dialect.MySQLMyISAMDialect OR org.hibernate.dialect.MySQLInnoDBDialect pour voir celui qui vous convient. 

Globalement, votre dialecte actuel génère, type=MyISAM alors qu'il devrait l'être, ENGINE=MyISAM dans la requête de création de table. 

erreur mysql 'TYPE = MyISAM'

Vous devriez également lire ceci, Pourquoi dois-je configurer le dialecte SQL d’une source de données?

Vos journaux indiquent que cette requête a été exécutée, create table MyTable (id integer not null, name varchar(255), primary key (id)) type=MyISAM. Vous devez donc essayer de l'exécuter directement à l'invite de la commande mysql pour voir si cela fonctionne pour votre version de MySQL. 

Aussi, en question, spécifiez également votre version de MySQL.

J'espère que ça aide !!

La raison pour laquelle vous faites face à cette erreur peut être l'une des raisons ci-dessous: -

  • Le nom de la colonne dans le script de base de données et la classe de modèle/entité sont différents.
  • Il y a une faute d'orthographe dans votre fichier de configuration en mentionnant la valeur de la propriété.
  • La version de MySQL ne correspond pas au dialecte que vous mentionnez.

Je faisais face à cette erreur parce que je modifiais les noms de colonne dans mon script de base de données, mais que j'avais oublié de le changer dans la classe modèle/entité. Donc, après 4 heures de traction, je l'ai simplement fait et mon application a commencé à fonctionner.

Modification dans le fichier XML de configuration en veille prolongée.

  <!-- SQL dialect -->      
  <property name="dialect">org.hibernate.dialect.MySQL5Dialect</property>

Ganesh Giri

Vérifiez vos erreurs de valeur de propriété.

Cela se produit parfois lorsque vous oubliez simplement le 't' dans Dialec , qui doit être Dialect , simplement une faute d'orthographe ou une erreur de valeur dans votre configuration.

Vous utilisez une version mise à jour de MySQL mais vous utilisez et old dialect

Utilisez soit,

<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property>

OR

<property name="hibernate.dialect">org.hibernate.dialect.MySQL8Dialect</property>

dans le fichier hibernate.cfg.xml.

Cela vous empêche d'obtenir les problèmes dialect.
