一、汽车浏览与售卖网
1.项目介绍:此项目运用jsp技术与JDBC技术实现了把页面与数据库的交互。满足了客户在
浏览网页的同时可以预订汽车，也让经销商减去了成本和时间。同时可以做到数据库与页面
的同步更新，在管理员登录网页时可以登录后台对网页及数据库的管理。管理员身份可以对
汽车进行添加，删除，并且可以修改汽车的价格和描述，也可以对注册的用户进行身份的修
改。因为只有一周时间和是自己从数据库到页面到功能实现再到后台都是自己写，所以项目
还不算太完善，离自己心中的目标还差一些。
2.项目技术: 有html、jQuery、JavaScript、ajax、servlet、easyui框架、MVC分层架构
3，项目的包package：如图所示

4：webRoot下的css，js，jquer和jsp，如图所示：
5，页面中显示汽车详细信息：

二，三味书屋网络小说网站
1. 开发工具：MyEclipse+Tomact+Oracle+PowerDesigner
2.项目介绍：此项目是服务广大网络小说的爱好者，和网络小说原创者的网站。这是一个
小组项目，运用了Spring + struts2 + Hibernate 框架技术，在此次项目中数据库的设计
给用户分了三种身份，管理员，作家和普通读者，我在此次项目也参加了框架的搭建整合，
并且完成了用户注册，登录，和作者上传作品，管理员后台的页面和功能，并对数据库进行
优化。
3.技术要点:运用了DIV+CSS+JS页面布局，ssh框架技术，SQL语言。4，主要文件及包：
5，此项目运用了Spring+Struts2+Hibernate框架技术，
在myeclipse中加载完项目所需要的jar包后会自动生成对应的xml配置文件，根据项目功能需要然后对项目进行配置。
如图struts.xml文件配置：
<?xml version="1.0" encoding="UTF-8" ?>
