我正在使用Hibernate 4+ Spring MVC 4，当我开始时Apache Tomcat Server 8出现此错误：

Error creating bean with name 'welcome': Injection of autowired dependencies failed;
Could not autowire field: private dao.IRegion controller.welcome.regionI;
No qualifying bean of type [dao.IRegion] 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)}

这是我的hibernate配置，其中包含<property name="packagesToScan" value="dao" />：

<?xml version="1.0" encoding="UTF-8"?>

   </bean>

   <bean id="persistenceExceptionTranslationPostProcessor" class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor"/>

</beans>

dao 是我放置dao和接口的软件包。

我的区域界面dao.IRegion：

public interface IRegion<T extends Serializable> {

    List<T> findAll();

}

我的地区DAO dao.RegionDAO

@Repository
public class RegionDAO  implements IRegion < Region > {

    @Autowired
    private SessionFactory sessionFactory;

    @Override
    public List<Region> findAll() {

        return  sessionFactory.getCurrentSession().createQuery("from Region").list();
    }

}

我的控制器

@Controller
public class welcome {

    @Autowired
    private IRegion<Region> regionI;
        ....

}

我的servlet调度程序
