spring - 坟墓 : Error listenerStart

Question

当我尝试运行我的应用程序时出现此错误，我不知道为什么...

GRAVE: Error listenerStart 11 sept. 2011 23:37:04 org.apache.catalina.core.StandardContext startInternal GRAVE:Error Starting context [/ gest_project] following previous errors

这是我的 web xml:

问候。

看起来你有一个类 gest_project.model.metier.ActeurServiceImp，我猜它使用了一个 @Service 或者 @Component 注释使它成为一个 Spring bean，看起来它实现了一个名为 gest_project.model.metier.ActeurService 的接口(interface)。该接口(interface)对您的应用不可用，因此出现 NoClassDefFoundError。
