这是我的基本动作

public class BaseAction {
    @Autowired
    protected FolderService folderService;
    @Autowired
    protected ArticleService fileService;
    @Autowired
    protected TemplateService themeService;
    @Autowired
    protected HeadlineService headlineService;
    protected final Logger logger = Logger.getLogger(this.getClass());
}

那就是我的FolderService

@Service
public class FolderService {
    protected final Logger logger = Logger.getLogger(this.getClass());
    @Autowired
    private FolderDao folderDao;
    @Autowired
    private AdminFolderDao adminFolderDao;
 ...................next is the java method
}
