完成三个jsp页面，要求如下：在login.jsp中，输入用户名和密码，提交到select.jsp页面，该页面有一个图书

login.jsp页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

 
   
   
   
 
 
    
 
 
 
 
 
 
   

select.jsp页面：

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

 
   
   
   
 
 
    
 
 
 
 
 
 
  <%String username=request.getParameter("username");
  session.setAttribute("username",username); %>
   

display.jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

 
   
   
   
 
 
    
 
 
 
 
 
 
  <% String book="";
  if(request.getParameter("book").equals("1")){
  book="Java Web应用开发基础";
  }
  if(request.getParameter("book").equals("2")){
  book="JSP程序设计";
  }
  if(request.getParameter("book").equals("3")){
  book="Java编程高手";
  }
  %>
    您好！<%=session.getAttribute("username") %>,您购买的图书是:<%=book %>
