我正在用spring和hibernate构建一个项目 sessionFactory 注入 setSessionFactory ，但是当我开始这个项目时，我得到了一个错误
道：

@Repository("osImageInfoDao")
public class OSImageInfoDao extends GenericDao<OSImageInfo, Integer> {

}

public class GenericDao<T, PK extends Serializable> {
    protected SessionFactory sessionFactory;

    @Autowired
    public void setSessionFactory(final SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }
}

启动项目时，出现一个错误：
