上面代码是登录成功后的界面里的。 通过String admin = (String)session.getAttribute("admin"); 获得登录成功后的用户Id，如何加代码使得登录成功后的界面获得该用户的admin_psw和amin_sex

那边已经回答了、给你写个demo看看
- Java code
public List<LinkDTO> queryUser(String name) { conn = ConnDB.getConn(); List<LinkDTO> list = new ArrayList<LinkDTO>(); String sql = "select Id,NickName,Others from tb_link where UserName = ?"; try { ps = conn.prepareStatement(sql); ps.setString(1, name); rs = ps.executeQuery(); while (rs.next()) { LinkDTO ldto = new LinkDTO(); ldto.setId(rs.getInt("Id")); ldto.setOthers(rs.getString("Others")); ldto.setNickname(rs.getString("NickName")); list.add(ldto); [color=#FF0000]session.setAttribute("user",ldto);[/color] } } catch (SQLException e) { e.printStackTrace(); } finally { ConnDB.closeConn(conn); } return list; }

你不是都写了么，稍微加两句。。。
if (rs.next() ){
out.println(rs.getString("admin_psw"));//获取admin_psw
out.println(rs.getString("amin_sex "));//获取amin_sex
out.println("你好，"+admin);
}
还有你的sql有点问题，改一下
String sql = "select admin_id,admin_psw,admin_sex from admin where admin_id='"+admin+"'";
------解决方案--------------------------------------------------------
你应该有个admin的实体类
String sql = "select admin_id,admin_psw.amin_sex from admin where admin_id='"+admin+"'";
ResultSet rs = sqlbean.executeQuery(sql);
if (rs.next() ){
//查询数据信息存在在实体类中,具体admin方法已实际为准
admin bean=new admin();
bean.setId（rs.getString("admin_id")）;
bean.setPsw(rs.getString("admin_psw));
bean.setSex(rs.getString("admin_sex"));
out.println("你好，"+admin);}
}
//将admin放在session中，取出时${admin.id}即可
request.setArrtibutre("admin",admin);
------解决方案--------------------------------------------------------
看着想新手
if (rs.next() ){
out.println(rs.getString("admin_psw"));//获取admin_psw
out.println(rs.getString("amin_sex "));//获取amin_sex
out.println("你好，"+admin);
}这样就行了，不用看别的什么了 javabean 你现在用不到 demo什么的你也....
------解决方案--------------------------------------------------------
用 rs.getString("admin_sex") 就可以获取了！
request.setSession()放到这里
登录后你可以把得到的放到session 里面 然后 request.getSession（）取出来就可以了
