public class InitIndexAction extends DispatchAction {
private IFoodInfoDAO iFoodInfoDAO;
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) {
List
foodInfos=iFoodInfoDAO.findAll(2);执行到这里iFoodInfoDAO=null，配置都是正确的啊？
request.setAttribute("foodInfos", foodInfos);
return mapping.findForward("ok");
}
public IFoodInfoDAO getiFoodInfoDAO() {
return iFoodInfoDAO;
}
public void setiFoodInfoDAO(IFoodInfoDAO iFoodInfoDAO) {
this.iFoodInfoDAO = iFoodInfoDAO;
}
输入InitIndexAction.do时候
foodInfos=iFoodInfoDAO.findAll(2);执行到这里iFoodInfoDAO=null，配置都是正确的啊，高手给看看。
