使用struts1框架，自定義的user繼承ActionForm，public class AddUserAction extends Action { @Override public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response) throws Exception { // TODO Auto-generated method stub user u=(user)form; UserDao ud=new UserDao(); ud.addUser(u); return mapping.findForward("list"); }}使用ActionFrom獲取的表單輸入的user的用戶名為什么不支持中文啊？中文用戶名就是亂碼
