SEVERE：異常發送上下文初始化事件到類的監聽器實例org.springframework.web.context.ContextLoaderListener

我是新來的春天，我無法找出問題。請幫助我這個。我米即使在我的src位置定義了軟件包，也得不到classnotfound exeption。SEVERE：異常發送上下文初始化事件到類的監聽器實例org.springframework.web.context.ContextLoaderListener

和我添加了一個監聽器，你可以看到它被註釋掉在web.xml contextListener class.it也是在src代碼定義，但它給ClassNotFound的exception.please建議和幫助我在此

我高度懷疑'com.apalya.promo.beans'是一個類。您可能想要設置'packagesToScan'屬性而不是'LocalSessionFactoryBean'的'annotatedClasses'屬性。 –

是的Deinum，我犯了這個錯誤，並通過糾正它再次運行構建，但現在我得到相同類型的錯誤由：java.lang.ClassNotFoundException：com.apalya.promo.entity.User.where用戶類實際上存在於我的應用程序 –

不根據堆棧跟蹤。 –

由於com.apalya.promo.beans是一個包不類，因此它抱怨java.lang.IllegalArgumentException: Cannot find class。

您應該使用packagesToScan屬性而不是annotatedClasses或者，如果您仍想繼續使用annotatedClasses，請配置完全限定的實體類名稱。

我做了這個改變，我給了完全合格的實體類名稱，但仍然顯示相同的錯誤，我認爲這不是實際的問題Lovababu，可能會在配置XML文件中有一些錯誤，請幫助在此 –

請更新問題與新的配置更改和錯誤。 – Lovababu
