HibernateDaoSupport getHibernateTemplate retourne null

Invité · 21/11/2007, 14h05

Bonjour,

Je tente (vainement) de configurer un dao avec Spring et Hibernate. Mais lorsque je demande le HibernateTemplate je reçoit un null :

        System.out.println("Student : " + student);
        return student;

}

public class StudentManagerTest {
 
    /** Creates a new instance of StudenteManagerTest */
    public StudentManagerTest() {
    }
 
    public static void main(String[] args) {
 
        ApplicationContext ctx = 
                new FileSystemXmlApplicationContext("applicationContext.xml");
        StudentManager mngr = (StudentManager) ctx.getBean("studentManager");
 
        System.out.println("Student Manager :" + mngr);
        mngr.getStudent(3);
 
    }
}

et le résultat à la console (les logs d'hibrenate ne me sortent aucunes erreurs, que des TRACE, DEBUG et INFO) :

Student Manager :manager.StudentManager@5e222e
HibernateTemplate : null
Exception in thread "main" java.lang.NullPointerException

Je soupçone le fait de ne jamais injecter mon "HibernateTemplate" mais dans tous les fichiers de config que je trouve, je en vois jamais cette injection et je ne sais pas comment la créer.

Merci de m'éclairer

C'est assez bizarre en effet, apparement, l'HibernateTemplate est crée dans le setter de la sessionFactory de HibernateDaoSupport...

Tu sais vérifier que la sessionFacotry est bien différente de null ? ( normaleme,nt oui vu que tu l'injecte mais bon ... )

public class SpringHibernateStudentDao extends HibernateDaoSupport implements StudentDao {
 
    public Student getStudent(int id) throws DataAccessException {
        System.out.println("Session factory :" + getSessionFactory());
        HibernateTemplate hibtemp = getHibernateTemplate();
        System.out.println("HibernateTemplate : " + hibtemp);
        Student student = (Student) hibtemp.get(Student.class, id);
        System.out.println("Student : " + student);
        return student;
    }
...

mais le résultat ne vas te plaire :

Student Manager :manager.StudentManager@5e222e
Session factory :null
HibernateTemplate : null

Note : Je travaille avec NetBeans et j'ai divisé cela en plusieurs sous projets :
- MoiCommons (Beans généraux : Personne, Contact,..)
- ProjetCommons (Student)
- ProjetDao (StudentDao,..)
- ProjetServices (StudentManager, et Classe de test)
Toutes mes archives sont présentes dans ProjetServices (sur lequel je fais mes tests). Lorsque j'ai voulu rajouter getSessionFactiry(), j'ai du également ajouter la jar d'hibernate dans ProjetDao. Je suppose que ça n'a pas d'importance, c'est juste des délires de NteBeans mais bon..
Edit : Je viens de fusionner ProjetDao avec ProjetService et ça ne change pas. Donc ce n'est pa sle fait d'avoir de multiples sous projets

**Hikage** · 21/11/2007, 16h02

Heu vi .. alors la, j'ai du mal a comprendre ce qu'il se passe ...

As-tu possibilité de configurer log4j, et de mettre le niveau pour les classe org.spring à DEBUG voir TRACE?

Histoire de voir ce qu'il configure

MM j'ai une piste.

Montre le code de ton DaoFactory :p

Car tu récupere le StudentDao par la, mais si c'est la DaoFactory qui te retourne le StudentDao sans passer par l'ApplicationContext, ce n'est pas Spring qui gere, donc la SessionFactory n'est simplement pas injectée

HibernateDaoSupport getHibernateTemplate retourne null [Data]

Spring Java

Vue hybride
