Bonjour,

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

private CutPosteService itemService = new CutPosteService();

Tu l'instancie manuellement donc les dépendances dans cette classe ne seront pas injectées, donc null, d'où le NullPointerException. Contrairement à ce que tu as dans le test, tu l'injectes avec @Autowired, donc ses dépendances seront injectées par spring et ça passe.

A+.

**andry.aime** · 25/11/2016, 09h22

Pas le temps de lire en détail tous ces codes mais tu ne dois pas utiliser @ContextConfiguration(locations="classpath:laplace-servlet.xml") dans PosteBean. Tu as commentés pas mal de lignes dans les xml, édite ton message en ajoutant le langage dans la balise code. [code=xml], ... Vérifie que tes packages sont bien scannées.

T'as toujours un NullPointerException mais je ne pas que c'est le même, c'est itemService qui doit être null, vu que tu as commenté tous les component-scan. Tu utilises aussi spring-mvc? Peut-on voir ton web.xml?

**yLaplace** · 25/11/2016, 11h24

j'ai un doute mais je pense que le souci vien de ces lignes
laplace-servlet.xml

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<import resource="classpath:jdbc-context.xml" />

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<mvc:resources mapping="/resources/**" location="/resources/" cache-period="31556926"/>

étant donné que les resources ont été redirigé vers webapp/resources alors que la 1 ere ligne import le fichier jdbc-context d'un autre projet donc il doit se retrouver dans les resources. Mais dans lequel?
celui de l'appli par defaut src/java/resources ou celui du webapp/resources?
Je penses que le fichier doit se trouver dans le 1 er enfin je pense et comme il y a une redirection des resources alors il le cherche peut être dans le second.
Si c'est le cas comment resoudre cela?

c'est itemService qui doit être null, vu que tu as commenté tous les component-scan

même quand je active cette ligne commentée c'est pareil. au fait le fichier jdbc-context.xml contient deja

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

<context:component-scan base-package="org.laplace" />

c'est pourquoi c'est commenté dans le fichier laplace-servlet.xml
