java 我做了简单的用户注册系统，现在我要把用户注册的信息显示在jsp页面上，该怎么写？
我记得老师好像在显示的jsp？这是我的部分servlet类代码（变量的定义在图片里）：
if (b) {
notice = "添加用户成功！";
UserBean user=ud.getOneUser(username);
request.setAttribute("abc",username);
send="Chenggong.jsp";
}
我该怎么写Chenggong.jsp的代码才可以显示该注册用户信息？答案：这是我的代码你看了就懂了，方法是一样的
HandleRegister.java
package bean;
import bean.BaseDAO;
import bean.Regiser;
import bean.*;
import java.sql.*;
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HandleRegister extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {doPost(request,response);
}
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
response.setContentType("text/html;charset=gb2312");
request.setCharacterEncoding("gb2312");
BaseDAO bd = new BaseDAO();
Regiser reg = new Regiser();
request.setAttribute("regiser",reg);
String logname=request.getParameter("logname").trim();
String password=request.getParameter("password").trim();
String email=request.getParameter("email").trim();
String phone=request.getParameter("phone").trim();
String message=request.getParameter("message");
String backNews="";
try{String insert="insert into member values ('"+logname+"','"+password+"','"+phone+"','"+email+"','"+message+"')";
int n=bd.Exec(insert);
if(n!=0){
backNews="注册成功";
reg.setBackNews(backNews);
reg.setLogname(logname);
reg.setEmail(email);
reg.setPassword(password);
reg.setMessage(message);
reg.setPhone(phone);
}
}
catch(Exception exp){
backNews="该用户名已被使用";
reg.setBackNews(backNews);
}
RequestDispatcher dispather=request.getRequestDispatcher("showRegister.jsp");
dispather.forward(request, response);
}
}
显示页面showRegister.jsp
<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%@ page import="bean.Regiser"%>
<jsp:useBean id="regiser" type="bean.Regiser" scope="request"/>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

其中还有俩个java文件，一个是存放模型的get和set方法的，一个是表单。你既然写到这里了你应该懂得。我就不贴出来了
也可以用${regiser.logname }直接调用，显示出来，这个就不详细解释其他：//这句是用response跳转到你要跳转的页面，并将值usename传递过去，
response.sendRedirect("你要跳转的页面.jsp?usename="+usename);
//在你要跳转的页面，就用request获取就行了。
<h1><%=request.getParameter("usename")%>!欢迎你的登陆！</h1>
具体的话，应该是这么写，其实也还有其他的方法，我就只记得这一个了，希望能帮到你 在JSP页里取到你的UserBean对象
<%=us.getUserName()%>
这样 ${abc} 上一个：jsp 用户注册页面设计 提交之前 如果 实现判断
下一个：JSP的onchange具体用法和举例
