SEVERE：将上下文初始化事件发送到类org.springframework.web.context.ContextLoaderListener的侦听器实例的异常

时间：2017-08-21 09:31:00

标签： spring hibernate spring-mvc

我是春天的新手，我无法弄清楚这个问题。请帮我解决这个问题。即使在我的src位置定义了包，我也得到了classnotfound exeption。

我已经添加了一个监听器，因为你可以看到它在web.xml contextListener类中被注释。它也在src代码中定义但它给出了classNotFound异常。请建议并帮助我这个

答案 0 :(得分：0)

由于 com.apalya.promo.beans 是一个不是类的包，因此它会抱怨java.lang.IllegalArgumentException: Cannot find class。

如果您仍想继续使用packagesToScan，则应使用annotatedClasses属性而不是annotatedClasses或配置完全限定的实体类名称。
