练习点设计: 删除、新增
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
+Servle
t+JavaBean
或SpringMVC
+Spring
+Mybatis
。
二、实现功能
随着银行卡越来越多,办卡人员日益增多,特需要银行卡系统:
1.首页默认显示所有银行卡信息,默认按照银行卡余额升序,如图1所示。
2.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3和图4所示。
3.用户点击“添加银行卡”操作链接,跳转到银行卡添加界面,填写完相关信息后点击添加按钮,增加银行卡信息数据到数据库,且页面跳转到列表页面展示最新数据,如图6和图7所示。
三、数据库设计
1.创建数据库(card_db)。
2.创建数据表(tb_card),结构如下。
字段名 | 说明 | 字段类型 | 长度 | 备注 |
---|---|---|---|---|
id | 编号 | int | 主键,自增,增量为1 | |
name | 持卡人姓名 | varchar | 50 | 不能为空 |
sex | 持卡人性别 | Char | 1 | 不能为空 |
cardNo | 卡号 | int | 不能为空 | |
balance | 银行卡余额 | Double | 不能为空 | |
level | 银行卡级别 | int | 1普卡 2 白金卡 3黑卡 |
四、推荐实现步骤
1.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。
2.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。
五、实现代码
1、MySQL数据库
card_db
2、项目Java代码
