《Web程序设计》课后习题附答案第一章1.填空题(1).NET Framework 主要包括公共语言运行库 CLR 和类库。
(2)/doc/da9346473.html, 网站在编译时，首先将语言代码编译成微软中间语言 MSIL 。
(3)一台 IIS Web 服务器 IP 地址为 210.78.60.19，网站端口号为8000，则要访问虚拟目录 xxxy 中default.aspx 的URL 为http://210.78.60.19.8000/xxxy/default.aspx 。
(4)可以通过复制网站同步网站上的一个文件。
2.是非题(1)托管代码是以CLR 为基础运行的代码。
（√）(2)若某页面上包含动画内容，则该页面肯定是动态页面。
（×）(3)一个网站中可以同时包含静态页面和动态页面。
（√）(4) /doc/da9346473.html,4.5 页面是边解释边执行的。
（×）(5)在VSEW2012 中开发网站必须安装独立的IIS。
（×）(6)IIS EXPRESS 具有与IIS 类似的功能，但主要用于VSEW2012 中的页面。
（×） (7)IIS 中的网站与VSEW2012 中的网站是相同的概念。
（×）3.简答题(1)一个学校有多个分院，每个分院有各自的网站，如果提供一台WEB 服务器，如何设置？每个分院设置各自的虚拟目录。
虚拟目录是服务器硬盘上通常不再主目录下的文件夹的一个好记名称（别名），使用别名可以发布多个文件夹下的内容以供所有用户访问，并能单独控制每个虚拟目录的读写权限。
(2)如何设置在访问网站时只需输入域名就可访问网页主页？将“i ndex.aspx”设置为默认文档，只要将其添加为默认文档即可，右击桌面“我的电脑”，选择“管理”项打开“计算机管理”窗口，选择“Internet 信息服务→网站→默认网站”并右击之，选择弹出菜单中的“属性”项，在打开的窗口中选择“文档”标签，单击“添加”将“index.aspx”添加进来，最后“应用→确定”即可(3)文件系统、本地 IIS、FTP 站点和远程站点的区别是什么？文件系统：就是发布到硬盘的文件本地 IIS：是发布到 IIS 根目录下的文件FTP 站点：是用过 ftp 上传到指定服务器的文件远程站点：就是可以发布到远程服务器的文件(4)说明什么是虚拟主机，Internet 上提的虚拟主机是如何运行的？所谓虚拟主机，就是把一台运行在互联网上的服务器划分成多个“虚拟”的服务器，每一个虚拟主机都具有独立的域名和完整的Internet 服务器（支持 WWW、FTP、E-mail 等）功能。
第1章 Web应用开发简介习题答案1．Web在组成上包括______和______两部分。
答案：服务器客户端2．谈谈对面向对象的认识。
答案：面向对象将将要解决的问题分解成各个对象，建立对象的目的不是为了完成一个步骤，而是为了描叙解决问题中的各个步骤中的行为。
面向对象编程方式是建立在面向过程编程方式基础上，其最重要的改变在于面向对象编程中，程序将围绕被操作的对象来设计，而不是操作本身。
面向对象编程方式以类作为构造程序的基本单位，具有封装、抽象、继承、多态性等特点。
3．介绍几种常用的框架技术。
答案：Java中常用的框架。
1．StrutsStruts是Apac he 基金会Jak arta项目组的一个开源项目，是一个基于S u n J2EE平台的MVC框架，它将Serv let和J SP标签作为实现自身功能的一部分。
2．WebWorkWebWork是由OpenSym phony组织开发的，是一个基于W e b的MV C框架。
它在运行时通过Inte rcept or（拦截器）自动应用，因此脱离了A ction类。
3．Struts 2Struts 2是Apache基金会的一个开源项目，它建立在Struts框架与Web Work框架基础之上，继承了二者的优点，是目前非常流行的一个W e b框架。
4．SpringSpring是一个以IoC和AO P为核心的轻量级容器框架。
它提供了一系列的Jav a EE开发解决方案，包括表示层的S prin g MVC、持久层的Sp ring JDBC以及业务层事务管理等众多的企业级应用技术。
5．Hibern ateHibern ate是一个ORM（对象关系映射）框架，它对JDBC进行了轻量级的封装。
