1．编写一个UserJsp.jsp页面向用户显示姓名，页面使用useBean标准动作。要求同时使用setProperty动作将用户姓名设置为anne。getProperty动作用于获取anne的名字。

package com.ch5.bean;

public class User {

private String userName;

private String address;

private String password;

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

public String getAddress() {

return address;

}

public void setAddress(String address) {

this.address = address;

}

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>

<jsp:useBean id="user" class="com.ch5.bean.User"></jsp:useBean>

<jsp:setProperty property="userName" name="user" value="anne"/>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<head>

<title>My JSP 'index.jsp' starting page</title>

</head>

<body>

UserName:<jsp:getProperty name="user" property="userName"/><br>

</body>

2.创建一个JavaBean，用来接受汽车的颜色，以及表示汽车是否安装了空调的布尔值。如果布尔值为真，则汽车安装了空调；如果布尔值为假，则汽车未安装空调。该JavaBean返回颜色和布尔值(完成JavaBean，创建一个页面显示结果)。

package com.ch5.bean;

public class Car {

String color;

boolean airConditioner;

public String getColor() {

return color;

}

public void setColor(String color) {

this.color = color;

}

public boolean isAirConditioner() {

return airConditioner;

}

public void setAirConditioner(boolean airConditioner) {

this.airConditioner = airConditioner;

}

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

<html>

<head>

<title>My JSP 'CarJsp.jsp' starting page</title>

<!--

</head>

<body>

颜色：<input name="color" type="text"/><br/>

是否安装空调：<input name="airConditioner" type="checkbox"/><br/>

</form>

</body>

</html>

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>

String path = request.getContextPath();

String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

request.setCharacterEncoding("UTF-8");

<jsp:useBean id="car" class="com.ch5.bean.Car"></jsp:useBean>

<jsp:setProperty property="*" name="car"/>
