Authentification CAS de base + Spring Security

Bonsoir,

J'essaie de faire une authentification CAS de base mais j'ai l'impression que le filtre n'est pas pris en compte. C'est à dire que des que je lance mon projet, j'ai juste le "Hello World" qui s'affiche.

Mon code :
applicationContext-security.xml

Voilà, si vous avez une idée du pourquoi je suis preneur.

Merci d'avance.
