…基于 SSMSpring Spring MVC MyBatis框架构建电器网上订购系统可以为用户提供一个方便快捷的购物平台。以下将详细介绍该系统的开发流程包括需求分析、技术选型、数据库设计、项目结构搭建、主要功能实现以及前端页面设计。
需求分析
电器网上订购系统应具备以下功能
用户注册与登录商品展示与搜索购物车管理订单管理支付接口集成后台管理系统商品管理、订单管理、用户管理
技术选型
后端Java、Spring、Spring MVC、MyBatis前端HTML、CSS、JavaScript、JQuery数据库MySQL开发工具IntelliJ IDEA 或 Eclipse服务器Tomcat
数据库设计
创建数据库表以存储用户信息、商品信息、购物车信息、订单信息等。
用户表users
id (INT, 主键, 自增)username (VARCHAR)password (VARCHAR)email (VARCHAR)phone (VARCHAR)
商品表products
id (INT, 主键, 自增)name (VARCHAR)description (TEXT)price (DECIMAL)stock (INT)category (VARCHAR)image_url (VARCHAR)
购物车表cart_items
id (INT, 主键, 自增)user_id (INT, 外键)product_id (INT, 外键)quantity (INT)
订单表orders
id (INT, 主键, 自增)user_id (INT, 外键)order_date (DATETIME)total_price (DECIMAL)status (VARCHAR)
订单详情表order_details
id (INT, 主键, 自增)order_id (INT, 外键)product_id (INT, 外键)quantity (INT)price (DECIMAL)
项目结构搭建 创建 Maven 项目 在 IDE 中创建一个新的 Maven 项目。修改 pom.xml 文件添加必要的依赖项。 配置文件 application.propertiesspring.datasource.urljdbc:mysql://localhost:3306/electronics_store?useSSLfalseserverTimezoneUTC
