这是所写的修改类
public void updateUI(HttpServletRequest request, ActionForm form, UserDao userDao) throws GetException, IllegalAccessException, InvocationTargetException { String userIDStr = request.getParameter("userID"); if(userIDStr != null){ Integer userID = Integer.valueOf(userIDStr); UserForm userForm = (UserForm)form; User user = userDao.getUser(userID); BeanUtils.copyProperties(userForm, user); } List provs = new ArrayList(); provs.add("山西省"); provs.add("陕西省"); provs.add("河北省"); provs.add("山东省"); provs.add("新疆省"); request.setAttribute("provs", provs); } public void update(HttpServletRequest request, ActionForm form, UserDao userDao) throws IllegalAccessException, InvocationTargetException, UpdateException { UserForm userForm = (UserForm)form; User user = new User(); BeanUtils.copyProperties(user,userForm); userDao.updateUser(user);// userDao.updateUserByID(5); }
所调用的修改实现类是正确的 请问一下 怎么解决 谢谢
