Lorsque j'ai eu cette erreur, cela s'est avéré être dû au fait que j'essayais d'accéder au contexte d'application dans une initialisation de champ ou un constructeur dans une classe (dans ce cas, AuthenticationFilter étend UsernamePasswordAuthenticationFilter) qui est instancié AVANT LE CONTEXTE IS DISPONIBLE.

myField  = (MyClass)SpringApplicationContext.getBean(MyClass.BEAN_NAME);

En déplaçant cette instruction vers une méthode qui est appelée au début du cycle de vie de cette classe mais longtemps après le constructeur, l'erreur a été résolue et l'application a démarré normalement.

La chose vraiment ennuyeuse, comme pour la plupart de l'opacité du modèle d'injection de dépendance de Spring Boot, est que, à la fin de la journée, c'était un cas classique de NullPointerException, le journal ne donnait pas la classe et le numéro de ligne où l'erreur était en cours; donc j'étais seul à déduire des preuves indirectes ce qui se passait.
