[Spring-jersey] Injection de dépendance

Version imprimable

Bonjour,

J'essaie de développer un web service rest qui accède à une base de données avec hibernate mais cela me provoque une exception lorsque que je souhaite interroger ma base : NullPointer.
Mon problème je pense est que je ne vois pas comment déclarer mon applicationContext.xml

voici mon web.xml:

J'ai bien déclarer mon applicationContext.xml mais j'ai toujours le null pointer.
J'utiliser jersey pour mon web service.

Quand je veut passer via l'interface avec l'annotation autowired, sa provoque le null pointer, il ne veux pas passer par ma ligne de code et quand je fait un new de la classe qui compote la méthode à appeler, tout se passe bein

Soit les membres du forum vont utiliser une boule de cristal pour trouver l'erreur, là, tu pourras avoir un malheur.
Soit tu montres le stacktrace complet de l'erreur, applicationContext.xml, le code java, web.xml, pom.xml si tu utilises maven, des âmes charitables pourront t'aider.

A+.

Voilà mon pom.xml

		String jsonInString = mapper.writeValueAsString(listeUtilisateurs);
 
		// Return JSON Data of table content
		return Response.status(200).entity(jsonInString).build();
//		return "Bonjour";
	}
}

C'est lors de l'appel de cette ligne List<Utilisateur> listeUtilisateurs = utilisateurDao.list(); que l'erreur se produit. Il ne passe même pas dans la ligne. J'ai l'impression qu'il rejette les interface ou bien les annotation @Autowired

Bonjour,

Citation:

Code:

<bean id="utilisateurDao" class="com.essaie.webservice.dao.impl.UtilisateurDaoImpl"></bean>

Je suspecte le NullPointerException dans la classe UtilisateurDaoImpl, que tu as oublié d'injecté quelque chose comme sessionFactory. Tu peux nous montrer le stracktrace complet de l'erreur et la classe UtilisateurDaoImpl?

A+.

Pour l'instant l'accès à la base de données se fait en dur et non en passant par le applicationContext.xml

En faisant un New UtilisateurDaoImplique dans monotre contrôleur sa passe nique la maison en passant par l'attribut autorités avec l'interface sa plante

1- T'as édité ton message son laissé un commentaire (merci pour la bonne foi et de faire perdre de temps aux lecteurs):
Au début t'avais

Citation:

at com.pds.webservice.controller.UtilisateurControllerRest.getUtilisateurs(UtilisateurControllerRest.java:43)

et maintenant

Citation:

at com.essai.webservice.controller.UtilisateurControllerRest.getUtilisateurs(UtilisateurControllerRest.java:43)

2- Pourquoi utiliser de très vielles versions de Jersey et de servlet pour une nouvelle application :weird::

Citation:

Envoyé par web.xml

xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">
Citation:
Envoyé par pom.xml
Code:

1 2 3 <groupId>com.sun.jersey</groupId> <artifactId>jersey-bundle</artifactId> <version>1.14</version>
3- Tu dois ajouter jersey-spring dans ton pom.xml et exclure les dépendances spring qui vont avec.
Code:

1 2 3 4 5 6 7 8 <dependency> <groupId>com.sun.jersey.contribs</groupId> <artifactId>jersey-spring</artifactId> <version>****</version> <exclusions>  </exclusions> </dependency>
4- Dans web.xml, remplace

Citation:

<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>

par

Code:

<servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>

5- Vire cette ligne de ton code:

Citation:

Code:

<bean id="utilisateurDao" class="com.essaie.webservice.dao.impl.UtilisateurDaoImpl"></bean>

6 - Tu dois seulement injecté sessionFactory dans UtilisateurDaoImpl et laisser hibernate gérer les connexions.

A+.

2- Pourquoi utiliser de très vielles versions de Jersey et de servlet pour une nouvelle application :
Je doit mettre quoi donc comme version de Jersey et de servlet?

Code:

<bean id="utilisateurDao" class="com.essaie.webservice.dao.impl.UtilisateurDaoImpl"></bean>

Si je met pas sa, il me dit qu'il peut pas accéder à l'attribut du controller Rest qui est en autowired
