练习点设计：修改、删除
一、语言和环境
- 实现语言：JAVA语言。
- 环境要求：MyEclipse/Eclipse + Tomcat + MySql。
- 使用技术：
Jsp+Servlet+JavaBean或SpringMVC+Spring+Mybatis。
二、实现功能
随着网上购物越来越多，电子订单也日益增多，特需要网上购物系统：
1.首页默认显示所有订单信息，如图所示。
2.正确显示订单状态和对应操作：1是已下单,操作为“发货和删除”;2是已发货，操作为“确认收获和删除”; 3是已收货，操作只有“删除”，如图所示。
图2 订单状态及对应操作
3.用户点击删除，则弹出提示框，用户点击确定后，删除选中数据并显示最新数据，如图所示。
4.用户点击“发货”操作链接,修改数据库中订单信息,且页面跳转到列表页面展示最新数据，如图所示。
5.用户点击“确定收货”操作链接,修改数据库中订单信息,且页面跳转到列表页面展示最新数据，如图所示。
三、具体要求及推荐实现步骤
JSP版本的实现步骤如下：
（1）按以上数据库要求建库、建表，并添加测试数据。
（2）创建Web工程并创建各个包，导入工程所需的jar文件。
（3）创建实体类。
（4）创建Servlet获取用户不同的请求，并将这些请求转发至业务处理层相应的业务方法。
（5）创建业务处理层，在其中定义业务方法实现系统需求，在这些业务方法中需要执行DAO方法。
（6）创建BaseDAO工具类，使用JDBC完成数据表数据的查询、删除和添加。
（7）编写JSP页面，展示数据的查询结果。SSM版本的实现步骤如下：
（1）创建数据库和数据表，添加测试数据（至少添加5条测试数据）。
（2）创建Web工程并创建各个包，导入工程所需的jar文件。
（3）添加相关SSM框架支持。
（4）配置项目所需要的各种配置文件（mybatis配置文件、spring配置文件、springMVC配置文件）。
（5）创建实体类。
（6）创建MyBatis操作数据库所需的Mapper接口及其Xml映射数据库操作语句文件。
（7）创建业务逻辑相应的接口及其实现类，实现相应的业务，并在类中加入对DAO/Mapper的引用和注入。
（8）创建Controller控制器类，在Controller中添加对业务逻辑类的引用和注入，并配置springMVC配置文件。
（9）创建相关的操作页面，并使用CSS对页面进行美化。
（10）实现页面的各项操作功能，并在相关地方进行验证，操作要人性化。
（11）调试运行成功后导出相关的数据库文件并提交。
四、数据库设计
1.创建数据库（Shops）。
2.创建数据表（shop_db），结构如下。
