ERREUR: ORA-02289: la séquence n'existe pas - org.hibernate.exception.SQLGrammarException: impossible d'extraire ResultSet

Je crée une application de mise en veille prolongée de base pour la table des employés dans laquelle j'ajoute, met à jour, supprime et affiche l'enregistrement à l'aide de la classe ManageEmployee.

En fait, ManageEmployee est ma classe de test et j'utilise le fichier Employee.Java et Employee.hbm.xml pour faire les choses ci-dessus.

Détails: Base de données: Oracle 11 g Hibernate version: hibernate-release-4.3.8.Final Java Version: Java 1.8

Détails de la table des employés:

USER_ID NUMBER (15,0) No 1 1
FIRST_NAME VARCHAR2 (20 BYTE) Oui 2
LAST_NAME VARCHAR2 (20 BYTE) Oui 3
NUMÉRO DE SALAIRE (10,0) Oui 4

Journal des erreurs: vous pouvez voir dans le journal que l'erreur arrive 3 fois car j'ajoute l'objet employé 3 fois dans la classe ManageEmployee.Java avec la méthode addEmployee (...), donc je suppose que le problème vient du générateur de séquence pour la colonne id.

Ici, j'utilise un générateur naïf. i.g. Entier empID1 = ME.addEmployee ("Zara", "ALi", 1000);

Il manque un générateur de séquence à la classe des employés, donc hibernate ne peut pas insérer la ligne. cela devrait être quelque chose comme ça qui augmente la colonne de nombre d'id de 1:

@Id
@GeneratedValue(strategy=GenerationType.SEQUENCE, generator="SEQUENCE1")
@SequenceGenerator(name="SEQUENCE1", sequenceName="SEQUENCE1", allocationSize=1)
private int user_id;

Asura

après avoir lu séquences Oracle et comment elles fonctionnent, ainsi que indiquant à Hibernate que vous utilisez une SEQUENCE (section 5.1.2.2.4) plutôt qu'un générateur natif, J'ai corrigé mes erreurs.

J'ai créé une séquence dans la base de données Oracle par la requête ci-dessous et mis à jour mon fichier hbm.xml

CREATE SEQUENCE TAB_CUSTOMER_SEQ
START WITH 1
MAXVALUE 999999999999999999999999999
MINVALUE 1
NOCYCLE
CACHE 20
NOORDER;
<id name="user_id" type="int" column="user_id">
