RegeditSerlet.java:

 

package aa;

import java.io.IOException;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class RegeditServlet extends HttpServlet{
 public void doPost(HttpServletRequest request,HttpServletResponse response)
      throws ServletException,IOException{
  String use = "";
  String sex="";
  String sexname = "";
  String password="";
  sex = request.getParameter("sex");
  use = request.getParameter("use");
  password = request.getParameter("password");
  request.setAttribute("sex",sex);//可以不要
  request.setAttribute("use",use);//可以不要
  request.setAttribute("password",password);//可以不要
      
   response.sendRedirect("/demo/disregedit.jsp?use="+use+"&password="+password+"&sex="+sex);
 }
 
}

 

regedit.jsp文件中,只要把下面语句修改一下:

.....

<form name="form" action="/demo/regedit" method="post">

...........

 

disregedit.jsp文件不变.

 

在web.xml里面增加如下语句:

....

     <servlet>
    <servlet-name>regedit</servlet-name>
    <servlet-class>aa.RegeditServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet> 
 
  <servlet-mapping>
    <servlet-name>regedit</servlet-name>
    <url-pattern>/regedit</url-pattern>
  </servlet-mapping>
