Erreur lors de la création du bean avec le nom 'org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping # 0' défini dans la ressource ServletContext

PROBLÈME:

Je crée un pointcut pour l'exécution d'une méthode dans une classe. Cette classe est une classe de contrôleur et notée par l'annotation @Controller et donc aucun bean n'est nécessaire pour la même chose qui est requise par l'aspect. J'attache le code de servlet dispathcher, l'aspect et la classe de contrôleur. Quelqu'un peut-il identifier le problème.

Il s'agit d'une limitation dans Spring AOP. Lorsque vous utilisez des points de coupe AspectJ pour tisser des aspects en beans, Spring utilise CGLIB pour générer une sous-classe de la cible et invoquer les aspects de cette sous-classe.

Cependant, si la classe cible n'a pas de constructeur public par défaut, cela échouera. CGLIB a la capacité de gérer cela, mais tout cela est caché derrière les trucs Spring AOP et vous ne pouvez pas changer ce comportement.

Je ne peux que vous suggérer de revenir à l'utilisation de l'injection de setter pour votre contrôleur, plutôt que de l'injection de constructeur. Ce n'est pas idéal, je sais, mais je ne peux penser à aucune autre solution.
