无法自动连线栏位：无法连线至com.sun.proxy$ Proxy22

通常，这意味着有一个委派给您的bean的AOP代理。例如，如果您使用注释了一种方法@Transaction。

解决方法

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

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