@IocBean
public class ClueDataService   extends HttpServlet {
	private  Log log = Logs.getLog(ClueDataService.class);
	@Inject
	private ClueDataDao   clueDataDao;	
	private ClueLoginDao   clueLoginDao;
。。。

public Boolean checkClueName(HttpServletRequest request, HttpServletResponse response) {
		String clueName = request.getParameter("clue_name");
		Integer clueId = Integer.parseInt(request.getParameter("clue_id"));
		return clueDataDao.checkClueName(clueName,clueId);
	}

	public String getCheckClueList(HttpServletRequest request, HttpServletResponse response) {
		Integer userId = Integer.parseInt(request.getParameter("user_id"));
		Integer userType = Integer.parseInt(request.getParameter("user_type"));
		return clueLoginDao.getClueIdByUserID(userId,userType);
	}

通过调试发现 clueDataDao是正常的 但是clueLoginDao为null
