基于Spring MVC + Spring + MyBatis的【银行卡系统】

资源下载:https://download.csdn.net/download/weixin_44893902/45604256

练习点设计: 删除、新增

一、语言和环境

  1. 实现语言:JAVA语言。
  2. 环境要求:MyEclipse/Eclipse + Tomcat + MySql。
  3. 使用技术:Jsp+Servlet+JavaBeanSpringMVC + 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。
图1 首页显示所有银行卡信息
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。图3 确认删除提示窗口 在这里插入图片描述

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。
 图4 数据删除后显示最新数据

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varchar50不能为空
sex持卡人性别Char1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int1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。
