الربيع - java.lang.IllegalArgumentException

Question

هذا يقودني إلى الجنون - لقد بحثت ووجدت منشورات تحتوي على أخطاء مماثلة، ولكن يبدو أن أيًا من الحلول لا يعمل لصالحي.

حسنًا، يخبرك مكدس الاستدعاءات بالسبب:

Initialization of bean failed; nested exception is
    java.lang.IllegalArgumentException: warning no match for this type name:
    coreservlets.aopaspj.service.DepartmentService [Xlint:invalidAbsoluteTypeName]

بالنسبة لي يبدو كما لو كنت تستخدم اسم فئة مثل Foo في إحدى نقاطك الجانبية، لكن Spring-AOP تتوقع شخصًا مؤهلاً بالكامل مثل com.blah.Foo.نظرًا لأنك لم تنشر رمز الجانب الخاص بك، فمن الصعب معرفة ذلك.أنا لست من مستخدمي Spring، ولكنه مأزق شائع في AspectJ أيضًا، خاصة إذا كنت لا تستخدم بناء الجملة الأصلي (حيث يمكنك استخدام الواردات العادية لتقصير أسماء الفئات في Pointcuts) ولكن بناء جملة نمط التعليقات التوضيحية.هذا الأخير يريد أسماء فئات مؤهلة بالكامل.
