1. JSP网页

<%@page import="com.example.bean.Person"%>
<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
    
    
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JavaBean的使用</title>
</head>
<body>
	<jsp:useBean id="person" class="com.example.bean.Person"></jsp:useBean>
	<jsp:getProperty property="name" name="person" /><br>
	<jsp:getProperty property="age" name="person" /><br>
	<jsp:getProperty property="address" name="person"/><br>
	<jsp:setProperty property="name" name="person" value="lisi"/>
	<jsp:getProperty property="name" name="person" /><br>
	<%= person.getName() %>
</body>
</html>

　　2. Person类

package com.example.bean;

public class Person {
	private String name = "zhangsan";
	private int age = 10;
	private String address = "beijing";
	
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public int getAge() {
		return age;
	}
	public void setAge(int age) {
		this.age = age;
	}
	public String getAddress() {
		return address;
