摘要信息: 电子商城系统主要功能包括:用户注册、用户登录、用户查看商城商品、用户购买商品、用户查看购物车并且清空购物车、用户找回账户以及密码、管理员登录、管理员注册、管理员查看用户信息、管理员删除用户信息、管理员删除商品信息、管理员添加商品信息、管理员修改商品信息、退出登录等。 图形可视化界面运行下能够显示系统启动进度条,删除、添加、注册等相关操作时能够弹出窗口加以提示,退出登录或系统时能够做到单击确认退出按钮才退出登录或系统,能够对用户加以提示。 注册用户或是管理员、添加商品信息、购买商品、删除商品或是用户信息、修改商品信息等相关操作时能够判断有无该用户或是商品。 用户在购买商品的时候同时更新商品的库存数量,管理员删除管理员时可以做到同时删除用户的购买信息。
主要内容:
一、项目名称 基于JAVASE的电子商城系统
二、功能要求 1、用户注册 2、用户登录 3、用户查看商品列表 4、用户购买商品 5、用户查看购买商品列表 6、用户清空购物车 7、用户找回账户和密码 8、管理员登录 9、管理员注册 10、查看用户信息 11、查看商品信息 12、删除用户信息 13、删除商品信息 14、添加商品信息 15、修改商品信息 16、退出用户登录 17、退出管理员登录 18、退出商城 三、需求分析 该系统的用户是商城消费者和商城管理者,根据客户的要求,可以注册、登录、购物、查看购物车信息、找回账户和密码,管理员可以对商品信息进行增加、修改、删除操作,可以对用户进行查看和删除。
四、设计** 1、在控制台与图形可视化界面下运行 2、使用Mysql数据库存取用户登录信息和商品信息 3、使用List存取商品购买信息 4、把程序分为多个类,多个类之间的互相调用。 5、用户或是管理员进行注册、登录时能够提供校验码。 6、用户或是管理员获取数据库信息时能够与数据库进行交互。 7、用户购物要做到简洁明了。 8、用户只需要身份证号码和邮箱地址就能找回账户和密码。 9、注册、删除、修改等操作要有信息提示。 10、用户、管理员进行操作时能够做到操作提示与用户名提示。 11、退出登录或是退出系统时能够做到让用户有所考虑。
五、具体实现 1、技术思路: 界面:基于控制台与图形可视化界面(Swing)实现用户的输入和输出。 程序流程:在函数中利用循环与递归 ,读取用户输入,调用模块实现各个子功能。 2、功能子模块划分: ① 注册模块 ② 登录模块 ③ 查看商品模块(查看商品列表,购买商品) ④ 查看购买商品信息 ⑤ 管理员登录(添加管理员信息,对商品信息进行查看、增加、 修改、删除,对用户信息进行查看、删除,删除用户信息 时能够做到同时删除消费记录) ⑥ 退出系统
六、运行截图 1、商城系统启动进度条(进度条能够做到动态加载):
2、商城主界面:
3、用户注册界面(填写注册信息不符合要求时能够弹窗提示、并 且判断用户名是否重复等):
4、用户登录界面(账户、密码不一致时能弹窗提示):
5、用户服务选择界面(能够提示用户名):
6、购买商品界面(能够判断输入的商品序号是否正确):
7、查看购物车界面(能够一键清空购物车):
8、查看商城商品信息界面:
9、管理员登录界面:
10、找回账户与密码界面:
11、管理员服务选择界面:
12、添加管理员界面:
13、查看用户信息界面:
14、删除用户信息界面:
15、删除商品信息界面:
16、添加商品信息界面:
17、修改商品信息界面:
18、退出账号、管理员登录、商城系统时要有提示:
