[Débutant] ClassCastException après requête SQL

**tck-lt** · 06/12/2006, 15h16

Je continue d'avancer, j'ai créé mes getters et setters pour éviter les exceptions. je tente maintenant de récupérer des éléments dans ma base grâce au code test suivant :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

public class Test {
 
	 public static void main(String[] args)
		throws HibernateException {
 
		 Session session = HibernateUtil.currentSession();		 
		 SQLQuery myQuery = session.createSQLQuery("select * from abonne");
 
		 System.out.println("-----------> TAILLE : "+myQuery.list().size());
		 for (int i=0;i<myQuery.list().size();i++) {
			 Abonne abonne = (Abonne) myQuery.list().get(i);
			 if (abonne != null) {
				 System.out.println(abonne.getNom());
			 } else {
				 System.out.println("L'enregistrement est vide");
			 }
		 }
 
		 HibernateUtil.closeSession();
 
	 }
}

Malheureusement une exception est encore levée, cette-fois-ci au moment où je caste mon objet contenu dans ma "List". Voici l'exception :

Exception in thread "main" java.lang.ClassCastException: [Ljava.lang.Object;
	at hibernate.Test.main(Test.java:25)

Je trouve très bizarre le nom de la classe qui n'arrive pas à caster pourquoi il y a-t-il "[L" dans le nom de la classe de type Object.
Pour rappel, j'utlise MySQL/Hibernate/Tomcat/JSP sur Windows avec Eclipse 3.1.

Merci d'avance de m'aider à supprimer cette exception.

Et bien apparement c'est içi :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Abonne abonne = (Abonne) myQuery.list().get(i);

Il ne vaut mieux pas caster un objet comme ça, fait un test avant :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

if(myQuery.list().get(i) instanceof Abonne) {/***}

Si tu sors un élément d'une base de donnée, je doute que se soit un objet Java. Créer plutôt un nouvel objet Abonne à partir des infos de la base de données.

Merci pour ta réponse, mais dans ce cas-là avec Hibernate comment me conseilles-tu de récupérer mes éléments, car les logs Hibernate me donnent bien les informations contenues dans ma base (cf dans la partie code de la ligne 3454 à 3469 - j'en ai enlevé un bout) :

Code :

Les différents .list() n'exécutent ils pas plusieurs fois la requête ?

J'aurais écrit ta méthode différemment :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
3
4
5
6
7
8
9
10
11

Session session = HibernateUtil.currentSession();		 
SQLQuery myQuery = session.createSQLQuery("select * from abonne");
List liste =  myQuery.list();
 
System.out.println("-----------> TAILLE : "+ liste.size());
 
Iterator iter = liste.iterator();
while(iter.hasNext())
{
  Abonne abonne = (Abonne) iter.next();
  if (abonne != null)
  {
    System.out.println(abonne.getNom());
  }
  else
  {
    System.out.println("L'enregistrement est vide");			
  }
}
 
HibernateUtil.closeSession();

Vérifier la syntaxe, car j'ai écrit ça vite fait.

Bonjour,

Lorsque sur le nom d'une classe tu as [L c'est que ta classe est un tableau;

Tu devrais plutot écrire

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

10
11

public class Test {
 
	 public static void main(String[] args)
		throws HibernateException {
 
		 Session session = HibernateUtil.currentSession();		 
		 Query myQuery = session.createQuery("From Abonne");
                 List result = myQuery.list();
		 System.out.println("-----------> TAILLE :  "result.size());
// j'utilise un iterator mais tu peux prendre result.get(i)
		 for (Iterator it = result.iterator(); it.hasNext();) {
			 Abonne abonne = (Abonne) it.next();
			 System.out.println(abonne.getNom());
// abonne est forcement != null
//			 if (abonne != null) {
//				 System.out.println(abonne.getNom());
//			 } else {
//				 System.out.println("L'enregistrement est vide");
//			 }
		 }
 
		 HibernateUtil.closeSession();
 
	 }
}

Edit : arf devancé

Merci mais j'avais déjà essayé ça (j'aurais dû vous le préciser). Le problème avec cette requête en HQL (si j'ai bien compris) est que j'obitens l'exception suivante :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

Faut-il que je fasse comme avec l'autre classe (cf post précédent) ?

Bonjour,

il te manque apparemment la jar Ant dans ta bibliothèque.

**tck-lt** · 06/12/2006, 16h03

merci c'est que je viens de voir grâce à mon ami Google. C'est le bordel de reprendre un projet où chacun a mis son petit plug-in de son côté sur Eclipse.
