我有一个小的 Spring 应用程序，我正在尝试将 Hibernate 添加到它。这是我的 servlet 配置：

我有一个DatabaseUserDAO和一个DatabaseRoleDAO类，它们分别实现UserDAO和RoleDAO。两种实现也都带有注释@Repository。我没有实现任何服务类；我只是想启动并运行以确保我的配置正确。
我无法弄清楚出了什么问题。当应用程序启动时，我得到以下堆栈跟踪：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'databaseUserDAO': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire field: private org.hibernate.SessionFactory net.vivin.myapp.dao.DatabaseUserDAO.sessionFactory; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type [org.hibernate.SessionFactory] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency. Dependency annotations: {@org.springframework.beans.factory.annotation.Autowired(required=true)}
我知道我已经在我的 spring 配置中定义了会话工厂。为什么Spring没有看到它呢？
