La trace de la pile indique que vous êtes manquant org.aspectj.weaver.reflect.ReflectionWorld de votre classpath. Cela se retrouve dans la AspectJ Pots, soit aspectjweaver.jar ou aspectjtools.jar, selon la version.

pourquoi je devrais les avoir??je pense à un défaut de l'aop capacité vient de printemps 3 pack.n'est pas vrai?
- je ajouter aspectjweaver.jar et maintenant, je donne des nouvelles d'exception avec cet en-tête:Exception in thread "main" org.springframework.les haricots.usine.BeanCreationException: Erreur lors de la création de haricots avec le nom "knifeBean" défini dans le chemin de classe de ressource [codes/aspect.xml]: Initialisation du bean n'a pas; nested exception est org.springframework.aop.cadre.AopConfigException: Impossible de proxy classe cible parce que CGLIB2 n'est pas disponible. Ajouter CGLIB au chemin de classe, ou de spécifier des interfaces de proxy.
Ce qu'il dit - ajouter cglib au classpath
ouai..ok maintenant! merci beaucoup..j'ai accepté de vous

Il vous manque quelques dépendances.
Si vous utilisez maven ajouter ces dépendances:
```
  <dependency>
<groupId>org.aspectj</groupId>
<artifactId>aspectjtools</artifactId>
<version>1.6.2</version>
</dependency>
<dependency>
<groupId>cglib</groupId>
<artifactId>cglib</artifactId>
<version>2.2</version>
</dependency>
```
Sinon, il suffit de télécharger le besoin de pots et de les ajouter à votre classpath.

Mais si c'est nécessaire, la dépendance de Printemps, pourquoi ne Ressort pas de la déclarer comme une dépendance?
Je suis tombé sur cette même erreur à l'aide de Maven et de placer le aspectjtools dépendance fixe. Le cglib dépendance est inutile, car mon projet marche bien avec elle commenté. Merci, toutefois, pour l'accès rapide corrigé 🙂

Cglib ne devrait pas être nécessaire si vous exposer des interfaces pour chaque pojo.
