学生成绩管理系统出现问题

出现的错误总结：

1，在选择登陆的时候出现：权限失效，解决办法：在Action中加上：//学生登录

public String sdeng(){

List list=this.getIdengService().sdeng(xuehao, pass);

Map session=(Map) ActionContext.getContext().get("session");

if(list.size()>0){

Student student=(Student)list.get(0);

String xuehao=student.getSxuehao();

session.put("xuehao", xuehao);

session.put("list", list);

return "sok";

}

return "no";

}

//教师登录

public String tdeng(){

List list=this.getIdengService().tdeng(xuehao, pass);

Map session=(Map) ActionContext.getContext().get("session");

if(list.size()>0){

Teacher teacher=(Teacher)list.get(0);

String xuehao=teacher.getSxuehao();

session.put("xuehao", xuehao);

session.put("list", list);

return "tok";

}

return "no";

}

//管理员登入

public String adeng(){

List list=this.getIdengService().adeng(xuehao, pass);

Map session=(Map)ActionContext.getContext().get("session");

if(list.size()>0){

Admin admin=(Admin)list.get(0);

String xuehao=admin.getSxuehao();

session.put("xuehao", xuehao);

session.put("list", list);

return "aok";

}

return "no";

}

publicint getQx() {

return qx;

}

publicvoid setQx(int qx) {

this.qx = qx;

}

public String qxyz()

{HttpSession session = ServletActionContext.getRequest().getSession();

if(session.getAttribute("rand")==null){

return "error";

}

//获得图形校验码

String sf = (String) session.getAttribute("rand");

//如果图形校验码正确，判断帐号、密码是否正确

if(sf.equals(this.getYanzhengma())){

System.out.println(this.getQx());

if(this.qx==1)

{

return sdeng();

}

else

{

if(this.qx==2)

{

return tdeng();

}

else

{

return adeng();

}

else

return "error";

}

即可。

2，在学生查询个人资料出现：比如A登陆，但是在查询资料，出现的是查询数据库的第一条记录。

错误原因： <li><a href="sgrgl.action" target="rightFrame">个人资料</a></li>

解决办法： <li><a href="sgrgl.action?sxuehao=<%=student.getSxuehao() %>" target="rightFrame">个人资料</a></li>

3，在学生发布公告时候：出现；

You are seeing this page because development mode is enabled. Development mode, or devMode, enables extra debugging behaviors and reports to assist developers. To disable this mode, set:

struts.devMode=false

in your WEB-INF/classes/struts.properties file.

错误原因：<li><a href="student/messageadd.jsp" target="rightFrame">我的留言</a></li>

解决办法：

<result name="success">student/messageadd.jsp</result>

</action>

<result name="success">student/mok.jsp</result>

<result name="error">student/merror.jsp</result>

</action>

<li><a href="userid.action?sxuehao=<%=student.getSxuehao() %>" target="rightFrame">我的留言</a></li>

4.在修改密码的时候出现：比如原来密码是123，我把它修改为456后，它说修改成功，但是我在数据库查看是密码由原来的123变为了123456：

错误原因：jsp页面写错了name="Spass"：

<p>修改后的密码：<input type="password" name="Spass"></p>

解决办法：

<p>修改后的密码：<input type="password" name="Spass"></p>

即可

5.在教室添加学生成绩的时候出现：失败页面

错误原因：在Serviceimpl中忘记给返回值了

public List tjpai(String xtype, String cname) {

return ture;

}

解决办法：

public List tjpai(String xtype, String cname) {

returnthis.getItchengjiDao().tjpai( xtype, cname);

}

6.在管理员部分出现：

在管理员把发布公告的时候专项失败页面，经检查后，还是失败。

错误原因：我在数据库里没设置一个自增的值，又没在反向生产里面修改。

public Notice(String nmessage, String nadmin, Date ntime, String sxuehao,

String ntitle) {

this.nmessage = nmessage;

this.nadmin = nadmin;

this.ntime = ntime;

this.sxuehao = sxuehao;

this.ntitle = ntitle;

}

解决办法是：public Notice(String nid,String nmessage, String nadmin, Date ntime, String sxuehao,

String ntitle) {

this.nid = nid;

this.nmessage = nmessage;

this.nadmin = nadmin;

this.ntime = ntime;

this.sxuehao = sxuehao;

this.ntitle = ntitle;

}

这样就可以了

7.在添加教研室的时候出现错误页面，

错误原因：在Action里面我没封装完。

解决办法：我在Action里面把他们全部封完就可以了！！

8.在修改该教研室时候出现：
