比如本来是改的密码从1改到111，结果保存的时候，不同输入框的内容位置全部乱掉了，比如输入框A的内容保存到了输入框B上
我刚接触JSP，请问大大们这是什么原因？
下面是servlet的代码：
package com.gkd.servlet;
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import com.gkd.service.UpdateService;
import com.gkd.vo.UserVo;
/**
* Servlet implementation class UpdateServlet
*/
@WebServlet("/UpdateServlet")
public class UpdateServlet extends HttpServlet {
private static final long serialVersionUID = 1L;
/**
* @see HttpServlet#HttpServlet()
*/
public UpdateServlet() {
super();
// TODO Auto-generated constructor stub
}
/**
* @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
*/
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
doPost(request, response);
}
/**
* @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
*/
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
request.setCharacterEncoding("UTF-8");
String idNum = request.getParameter("idNum");
String userName = request.getParameter("userName");
String password = request.getParameter("password");
String phoneNum = request.getParameter("phoneNum");
String address = request.getParameter("address");
String sex = request.getParameter("sex");
String area = request.getParameter("area");
String credit = request.getParameter("credit");
String flg = request.getParameter("flg");
UserVo userVo = new UserVo(idNum, password, userName, phoneNum, address, area, sex, credit);
UpdateService updateService = new UpdateService();
UserVo userVo1 = updateService.findUserById(idNum);
if("preupd".equals(flg)){
request.setAttribute("userVo", userVo1);
request.setAttribute("password", userVo1.getPassword());
request.setAttribute("userName", userVo1.getUserName());
request.setAttribute("phoneNum", userVo1.getPhoneNum());
request.setAttribute("address", userVo1.getAddress());
request.setAttribute("area", userVo1.getArea());
request.setAttribute("sex", userVo1.getSex());
request.setAttribute("credit", userVo1.getCredit());
request.getRequestDispatcher("/grxx.jsp").forward(request, response);
}else if("update".equals(flg)){
boolean b = updateService.saveInfo(userVo);
String s=null;
if(b)
{
s="修改成功！";
}
else
{
s="修改失败！";
}
request.setAttribute("reminder", s);
request.setAttribute("userVo", userVo);
request.setAttribute("password", userVo.getPassword());
request.setAttribute("userName", userVo.getUserName());
request.setAttribute("phoneNum", userVo.getPhoneNum());
request.setAttribute("address", userVo.getAddress());
request.setAttribute("area", userVo.getArea());
request.setAttribute("sex", userVo.getSex());
request.getRequestDispatcher("/grxx.jsp").forward(request, response);
}
}
}
