我正在尝试在DepartmentService中注入DepartmentDAO.这是在我添加@Transactional注释后出现的.所以这是我的DepartmentService：
@Service
@Transactional
public class DepartmentService extends AbstractCRUDService
这是我的部门DAO：
@Repository
@Transactional(propagation = Propagation.MANDATORY)
public class DepartmentDAO extends AbstractCRUDDao
这是一个applicationContext.xml：
