Voilà les différentes classes qui semblent poser problèmes :

Si quelqu'un avait une piste, ça m'aiderait beaucoup !

Merci d'avance

Je suis pas certain de ma réponse mais je dirais que

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
@Service
public class ContactServiceImpl implements ContactService

devrait peut-être être remplacé par

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

1
2
@Service("ContactService")
public class ContactServiceImpl implements ContactService

?

Merci pour ton aide miles_
Malheureusement, j'ai le même problème avec "@Service("ContactService")"

[chewing-gum]

Je crois avoir repéré ton erreur. Le package que tu scannes est celui-ci :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

 <context:component-scan base-package="net.sebpx.subgeste.controller">

MAIS tu dois aussi scanner les autres packages, pas seulement tes controller... Tu dois notamment scanner le package qui contient la classe ContactServiceImpl . Sinon, comment Spring pourrait-il utiliser les beans dont il n'a pas connaissance ?

Bref, change simplement de package et écrit ça :

Code :

Sélectionner tout - Visualiser dans une fenêtre à part

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

ça scannera tout ton projet.

N'oublie pas d'ajouter l'annotation "@Service" sur la classe "ContactServiceImpl".

Pour terminer, tu t'es trompé dans ton diagnostique :

Je ne vois vraiment pas d'ou vient cette première erreur : "No matching bean of type [net.sebpx.subgeste.service.ContactService] found for dependency'. Cette classe existe !

Cela ne signifie pas que ta classe n'existe pas dans ton projet, mais ça signifie plutôt que Spring ne contient pas de définition de beans du type ContactService.

Ahh c'était exactement ça !
Merci beaucoup pour ton aide et tes explications chewing-gum !
