Int�gration de Redis pour une authentification JWT avec SpringBoot
Bonjour � tous !
Je rencontre deux probl�mes...
J'ai une application qui fonctionne avec Spring + JWT.
D�sormais je souhaite int�grer Redis pour le stockage des tokens, suite � beaucoup de modification, le probl�me est que j'ai une erreur de base, mais je n'arrive pas du tout � trouver sa source..
J'ai tout tent�, @Autowired ou non... toujours pareil..
Code:

.common.security.specific.jwt.JwtUtil.extractToken(javax.servlet.http.HttpServletRequest)" because "this.jwtUtil" is null
Le problème est identique avec "because "this.tokenService" is null"..
Bon en fait c'est à se demander si le autowired fonctionne.. aucune instanciation ne fonctionne.. |
Et mon deuxi�me probl�me, mais peut �tre li� au premier est qu'une fois que mon application m'a donn� le token, elle ne l'a pas ins�r� dans Redis ( alors que la connection est OK ).
Voila tout ce que j'ai c�t� code :
Merci pour l'aide !
