集成JSF，SPRING和Hibernate并始终得到错误-org.springframework.beans.factory.CannotLoadBeanClassException

Question

我是Spring的新手。尝试使用JSF Spring和Hibernate在Maven中构建Web项目，但似乎我的应用程序无法获取spring配置XML。

下面是堆栈跟踪：

Answer 1

我相信您的问题与组件扫描有关。在此blog中，似乎要使用您的配置，必须将以下注释@ManagedBean添加到bean中。

不过，还有一种更简单的方法来进行完整扫描，这使Spring可以为您完成扫描。为此，您可以尝试从 applicationContext.xml 中删除以下几行。

<!-- service -->
<bean id="userDetailsService" class="co.MyJavaCode.spring.service.impl.UserDetailsServiceImpl" />

<!-- dao -->
<bean id="userDetailsDao" class="co.MyJavaCode.spring.dao.impl.UserDetailsDaoImpl" />

删除这些行后，将以下行添加到同一文件中。

<context:component-scan base-package="co.MyJavaCode"/>

这将自动扫描所有带有@Component或@Service批注的文件。我添加了co.MyJavaCode作为基本程序包，因为看起来每个类都在该程序包中，但是如果没有，则只需创建一个基本程序包，然后将所有内容添加到该程序包中，然后将其用作自动扫描的参考即可。希望对您有帮助！
