项目名称
基于 JavaWeb 的蛋糕甜品商城
演示视频
= 基于 JavaWeb 的蛋糕甜品商城_哔哩哔哩_bilibili
零碎介绍
《基于 javaweb+mysql 的蛋糕 | 甜品商城》该我的项目含有源码、论文等材料、配套开发软件、软件装置教程、我的项目公布教程等
应用技术:
前端应用技术:JSP,HTML5,CSS3、JavaScript、jQuery、bootstrap 等
后盾应用技术:Servlet、JDBC 等
数据库:Mysql 数据库
本零碎为基于 jsp+servlet+mysql 的甜品 | 蛋糕零碎,蕴含前台注册用户和后盾管理员两种角色,性能如下:
管理员:治理前台注册用户的增删改查、管理员的增删改查、商品的增删改查、商品分类的增加删除、订单的搜寻删除及订单的提交发货操作
前台普通用户:查看商品,进入商品详情页,加购物车,下单,确认收货。
第三章 系统分析及设计
3.1 需要剖析
3.1.1 工作概述
该零碎为商家和顾客应用,提供商品在线分享购买的平台,零碎将分为用户和管理员两个角色,其中零碎用户局部的次要性能包含登录注册,前台商品分页浏览、搜寻性能,购物车性能,订单的生成、查看、批改、删除、领取,前台页面的拜访权限,管理员局部的性能有登录、商品的分页查看、增加、批改、删除、搜寻,订单的查看、搜寻,后盾页面的拜访权限等。
3.1.2 性能需要
前台性能需要
(1)用户的登录:对曾经注册的用户提供登录操作。
(2)用户的注册:针对还未注册的用户实现注册性能的应用,在注册的过程中波及数据的合法性校验,以及利用 ajax 实现用户名是否已被注册的异步校验。
(3)商品展现模块:通过分页浏览商品,也能够通过关键词搜寻商品。
(4)购物车: 用于寄存用户的购物内容,用户可依据本人的状况批改本人的购物车。
(5)订单模块: 对于曾经登录的用户能够对购物车内容进行付款生成订单,能够为本人的订单进行付款。
(6)前台页面的拜访权限:对已有账号拜访进行权限分类,用户只能进入前台。

环境须要
1. 运行环境:最好是 java jdk 1.8,咱们在这个平台上运行的。其余版本实践上也能够。
2.IDE 环境:IDEA,Eclipse,Myeclipse 都能够。举荐 IDEA;
3.tomcat 环境:Tomcat 7.x,8.x,9.x 版本均可
4. 硬件环境:windows 7/8/10 1G 内存以上;或者 Mac OS;
5. 数据库:MySql 5.7 版本;
6. 是否 Maven 我的项目:否;
技术栈
- 后端:Spring+SpringMVC+Mybatis
- 前端:JSP+CSS+JavaScript+jQuery
应用阐明
- 应用 Navicat 或者其它工具,在 mysql 中创立对应名称的数据库,并导入我的项目的 sql 文件;
- 应用 IDEA/Eclipse/MyEclipse 导入我的项目,Eclipse/MyEclipse 导入时,若为 maven 我的项目请抉择 maven;
若为 maven 我的项目,导入胜利后请执行 maven clean;maven install 命令,而后运行; - 将我的项目中 springmvc-servlet.xml 配置文件中的数据库配置改为本人的配置;
- 运行我的项目,在浏览器中输出 http://localhost:8080/ 登录
