problème avec la persistance des objets

Version imprimable

Bonjour tout le monde,

Je travaille à partir d'un tutoriel pour apprendre hibernate, c'est le tutoriel de julien DEFAUT.

J'ai suivi methodiquement, j'ai configuré correctement hibernate.

Mais lors de la compilation de cette page j'ai cette erreur qui est générée:

Apparement il te dit que tu n'as pas creer cette classe :
Code:

1 2 com.minosis.hibernate.TContact
As-tu creer la classe TContact?
As-tu creer le mapping?
L'as-tu ecris dans ton fichier de configuration?

Je te remercie de ta réponse aussi rapide.

J'ai bien créé la classe TContact, elle fait partie du package com.minosis.hibernate.

Il te faut definir chacun des mappings dans le fichier de configuration

Code:

<mapping resource="la_ou_tu_l_as_range/TContact.hbm.xml"/>

Jette un oeil sur la doc, tu comprendras certaines choses
http://www.hibernate.org/hib_docs/v3...iguration.html

Je te remercie de ton aide.

Je voudrais savoir, je mets ce bout de code:

Code:

<mapping resource="TContact.hbm.xml"/>

dans ce fichier là?:
Code:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE hibernate-configuration PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd"> <hibernate-configuration> <session-factory> <property name="hibernate.connection.driver_class">org.gjt.mm.mysql.Driver</property> <property name="hibernate.connection.url">jdbc:mysql://localhost/base1</property> <property name="hibernate.connection.username">root</property> <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property> </session-factory> </hibernate-configuration>
Si oui à quel emplacement, car là je viens de le mettre après le tag sessionfactory est la il a des erreurs.

NB:mon fichier "TContact.hbm.xml" est dans le scr
Je vous remercie de votre aide

Je voualis vous dire que j'ai résoulu le problème, il m'a bien rentré dans la base les infos.

Je ne vois pas d'erreur dans les messages que tu m'as passé.
ce sont juste des messages d'information.

ce que tu as fait me parait correct.

Parviens-tu a ecrire Jean Dupont dans la base de donnees?
Si oui c est que cela fonctionne.

Je te remercie.

Je parviens à écrire Jean Dupont dans la base de données mais par contre je ne parviens pas à le récupérer avec une requete SQL.

J'ai une question les requete SQL, il faut les écrire dans le fichier mapping car moi j'ai écris directement dans Test.Java car dans le tutoriel c'est là où il a écrit mais j'ai vu dans le forum, il a des personnes qui écrive dans le fichier mapping.

il te faut utiliser createQuery ou createSqlQuery

Jette un oeil ici :

gentil

Je te remercie de ton aide.

Je suis en train de regarder par conséquent si je comprend bien, il ne faut pas coder les requetes sql dans le mapping alors.

Je vous remercie

Je te remercie encore de ton aide.

J'ai modifier mon code mais des erreurs résides, visiblement il veut pas que je fasse des select .

createQuery prends la syntaxe HQL
createSQLQuery prends la syntaxe SQL

Tu as ecris une syntaxe SQL dans createQuery.

Dans ma base de donnée, je n'ai pas de champ "'id0_", ce ne compred pas pourquoi il me demande ce champ.

Code:

Iterator it= session.createSQLQuery("select * FROM t_contact").list().iterator();

A mon avis ceci est largement suffisant.(la syntaxe que tu utilises est deprecated)
Mais ca me parait plus simple en faisant la syntaxe HQL :
Code:

1 2 3 4 5 6 Iterator it= session.createSQLQuery("FROM TContact").list().iterator(); while(it.hasNext()) { TContact uncontact=(TContact) it.next(); System.out.println(uncontact.getAge()); }

gentil

Je te remercie de ton aide.

J'avais réussi avec la methode createSQLQuery mais je vais utiliser la methode que tu me dis car la mienne est obsolete.

Sinon avec la methode HQL, comment sélectionner certains champs, car on ne peut pas faire "select nom, prenom" par exemple.

Sinon j'ai ouvert une autre discussion afin de savoir si j'ai bien assimilé ces nouvelles notions.

Je te remercie de ton aide
