<jsp:useBean>

<jsp:setProperty>

<jsp:getProperty>

一，javabean类：

 1 package com.lyq.bean;
 2 
 3 public class Person {
 4     private String name;
 5     private int age;
 6     private String sex;
 7     private String add;
 8     public String getName() {
 9         return name;
10     }
11     public void setName(String name) {
12         this.name = name;
13     }
14     public int getAge() {
15         return age;
16     }
17     public void setAge(int age) {
18         this.age = age;
19     }
20     public String getSex() {
21         return sex;
22     }
23     public void setSex(String sex) {
24         this.sex = sex;
25     }
26     public String getAdd() {
27         return add;
28     }
29     public void setAdd(String add) {
30         this.add = add;
31     }
32     
33 }

二，初始页面

 1 <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
 2 <%
 3 String path = request.getContextPath();
 4 String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
 5 %>
 6 
 7 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
 8 <html>
 9   <head>
10     <base href="<%=basePath%>">
11     
12     <title>My JSP 'personindex.jsp' starting page</title>
13     
14     <meta http-equiv="pragma" content="no-cache">

26     <form action="personreg.jsp" method="post">
27     <table align="center" border="1" width="400" height="200">
28     <tr>
29         <td align="center" colspan="2">添加用户信息</td>
30     </tr>
31     <tr>
32         <td align="center">姓名:</td>
33         <td align="center"><input type="text" name="name"/></td>
34     </tr>
35     <tr>

51     
52     
53     </form>
54 
55   </body>
56 </html>
