首先看下面useBean结构分析

说明，权限路径即包名加类名。本处不详细解读jsp作用域，相关知识请移步学习。

依据上图，依次进行本次演示

1.建立如下javaBean类，首先创建一个User类

package cn.cowhair;public class User {private String username;private String password;public User() {super();}public String getUsername() {return username;}public void setUsername(String username) {this.username = username;}public String getPassword() {return password;}public void setPassword(String password) {this.password = password;}}

2.创建Jsp页面

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8" contentType="text/html; charset=utf-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html>  <head>       <title>My JSP 'index.jsp' starting page</title>  </head>    <body>    <jsp:useBean id="user" class="cn.cowhair.User" scope="page"></jsp:useBean>    <%     user.setUsername("張三");    out.print(user.getUsername());    %>  </body></html>

3.启动tomcat，输出内容
