Il s'agit bien des deux autowired qui sont à null. Je ne sais pas pourquoi celle ci est à null pourtant bien indiqué dans mon ApplicationContext

**tchize_** · 22/03/2016, 23h23

Ta classe UserResource est chargée par jersey, pas par Spring, il n'y a donc aucune injection car Spring ne la vois jamais. Il existe des manières spécifiques à Spring pour créer des webservice avec l'injection spring.

Ou tu passe à javaEE qui a ses propres services + injection CDI

**quentinb56** · 23/03/2016, 08h06

Pourtant je vois bien l'injection en utilisant

J'ai réussis à contourner le problème en modifiant le web.xml

en lancant :

TbUserDAO >> TbUserDAO created
TbUserDAO >> main.webapp.dao.TbUserDAO@2f1c1fe5
TbUserDAO >> class main.webapp.bean.TbUser
TbUserDAO >> null
UserResource >> UserResource created
UserResource >> main.webapp.rest.resources.UserResource@7534ac58
UserResource >> userService: main.webapp.dao.TbUserDAO@2f1c1fe5
UserResource >> authManager: org.springframework.security.authentication.ProviderManager@4838deb5

en essayant l'authentification:

Je ne vois pas pourquoi il appel TbUserDAO create

**tchize_** · 23/03/2016, 10h09

peut être parce que c'est ce que tu as écrit dans ton code à la ligne 158?

Pourtant je vois bien l'injection en utilisant

Vous avez bien une bean Spring injectée correctement - puisque c'est un @Component qui est dans le package concerné par le package-scan - mais Jersey créé une autre instance ignorée par Spring,
vous pourriez vous en rendre compte en ajoutant à vos logs le "this" : vous verrez alors qu'il y a bien 2 instances différentes :
celle pour laquelle le @PostContruct est invoqué par Spring et celle qui répond à la requête REST.

Si je comprends bien j'ai deux instances parallèles qui tournent une première pour Spring et une seconde pour jersey ? Les deux se lancent aux même moments et comment résoudre le problème ?

Le scope par défaut de Spring est le singleton, pour JAX-RS c'est la requête.
