Component Scanner : servlet et applicationContext.xml

**SebastianPx** · 16/03/2012, 20h21

Bonjour,

je développe actuellement une application Spring MvC et je voudrais utiliser Vaadin.
Jusque là, j’instanciais mon Component Scanner directement dans mes servlet.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<context:annotation-config />
<context:component-scan base-package="net.sebpx.subgeste" />

Je voudrais maintenant déclarer ceci dans un applicationContext.xml.
J'ai donc crée ce fichier dans mon WebContent/WEB-INF.
Il ressemble à ça :

    <!-- Activate Spring annotation support -->
    <context:annotation-config/>
    <context:component-scan base-package="net.sebpx.subgeste" />
 
</beans>

Le problème que j'ai, c'est que maintenant que je l'ai déplacé, quand je déploie le projet j'ai l'exception suivante :

GRAVE: Exception lors de l'envoi de l'évènement contexte initialisé (context initialized) à l'instance de classe d'écoute (listener) org.springframework.web.context.ContextLoaderListener

J'ai ensuite plein de BeanCreationException.

Est-ce que quelqu'un aurait une idée de comment je peux me sortir de là ?

Merci d'avance !

Tes exceptions te disent que tu n'as pas instancié de SessionFactory.
Du coup, la classe contactDAOImpl ne peut pas être utilisée si tu ne lui injectes pas de SessionFactory.

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

BeanCreationException: Error creating bean with name 'contactDAOImpl': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory net.sebpx.subgeste.dao.ContactDAOImpl.sessionFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.hibernate.SessionFactory] found for dependency

Solution : Déclare un bean de type SessionFactory dans ton applicationContext.xml.

Component Scanner : servlet et applicationContext.xml
