Guide contributeur

Direction de recherche
Examinez la séquence des hooks d'arrêt dans Spring Cloud Gateway, en vous concentrant sur la désenregistrement de ConsulServiceRegistry et le rafraîchissement de CachingRouteLocator qui déclenchent la création de beans après que le contexte est en cours de destruction. Envisagez d'ajouter des vérifications pour empêcher la création de beans pendant la phase de destruction ou de réorganiser les hooks d'arrêt.
