SEVERE：异常发送上下文初始化事件到类的监听器实例org.springframework.web.context.ContextLoaderListener

我是新来的春天，我无法找出问题。请帮助我这个。我米即使在我的src位置定义了软件包，也得不到classnotfound exeption。SEVERE：异常发送上下文初始化事件到类的监听器实例org.springframework.web.context.ContextLoaderListener

和我添加了一个监听器，你可以看到它被注释掉在web.xml contextListener class.it也是在src代码定义，但它给ClassNotFound的exception.please建议和帮助我在此

我高度怀疑'com.apalya.promo.beans'是一个类。您可能想要设置'packagesToScan'属性而不是'LocalSessionFactoryBean'的'annotatedClasses'属性。 –

是的Deinum，我犯了这个错误，并通过纠正它再次运行构建，但现在我得到相同类型的错误由：java.lang.ClassNotFoundException：com.apalya.promo.entity.User.where用户类实际上存在于我的应用程序 –

不根据堆栈跟踪。 –

由于com.apalya.promo.beans是一个包不类，因此它抱怨java.lang.IllegalArgumentException: Cannot find class。

您应该使用packagesToScan属性而不是annotatedClasses或者，如果您仍想继续使用annotatedClasses，请配置完全限定的实体类名称。

我做了这个改变，我给了完全合格的实体类名称，但仍然显示相同的错误，我认为这不是实际的问题Lovababu，可能会在配置XML文件中有一些错误，请帮助在此 –

请更新问题与新的配置更改和错误。 – Lovababu
