學生成績管理系統(tǒng)出現(xiàn)問題

1、);););出現(xiàn)的錯誤總結:1在選擇登陸的時候出現(xiàn)：權限失效，解決辦法：在Action中加上：/學生登錄publicString sde ng()List list= this .getIdengService().sdeng(xuehao , pass );Map sessi on=( Map)ActionCon text.getC on text().get( sessi onif (list.size()0)Stude nt stude nt=(Stude nt)list.get(O);String xuehao=stude nt.getSxuehao();sessi on. put(x

2、uehao , xuehao);sessi on. put(list , list);return sok;return no;/教師登錄publicString tde ng()List list= this .getIdengService().tdeng(xuehao , pass );Map sessi on=( Map)ActionCon text.getC on text().get( sessi onif (list.size()0)Teacher teacher=(Teacher)list.get(0);String xuehao=teacher.getSxuehao(); s

3、essi on. put(xuehao , xuehao);sessi on. put(list , list);return tok;return no;/管理員登入public String ade ng()List list= this .getIdengService().adeng(xuehao , pass );Map sessi on=( Map)Act ionCon text.getC on text().get(sessi onif (list.size()0)Admin admi n=(Admi n)list.get(O);String xuehao=adm in. get

5、rror ;/獲得圖形校驗碼String sf = (String) session.getAttribute(/如果圖形校驗碼正確，判斷帳號、密碼是否正確if (sf.equals( this .getYanzhengma()System.out .println( this .getQx();if (this . qx =1)retur nsde ng();elseif (this . qx =2)return tde ng();elseretur nade ng();elsereturn error即可。2，在學生查詢個人資料出現(xiàn)：比如A登陸，但是在查詢資料，出現(xiàn)的是查詢數(shù)據(jù)庫的第條記錄

15、;Messages:6.在管理員部分出現(xiàn)：在管理員把發(fā)布公告的時候專項失敗頁面，經(jīng)檢查后，還是失敗。 錯誤原因：我在數(shù)據(jù)庫里沒設置一個自增的值，又沒在反向生產里面修改。public Notice(Stri ngnm essage,String n adm in, Date n time, Stri ng sxuehao,Stri ng nti tle) this . nmessage = nmessage;this . nadmin = nadmin;this . ntime= ntime;this . sxuehao = sxuehao;this . ntitle= ntitle;解決辦法是
