1、开发相关技术介绍
1.1 SpringBoot框架
SpringBoot 是由 Pivotal 团队开发的开源 Java 基础框架，旨在简化 Spring 应用的初始搭建以及开发过程。它通过提供一系列的"Starters"来自动配置 Spring 及其集成的第三方库，极大地降低了开发者的配置难度。SpringBoot 应用通常可以独立运行，通常打包成 JAR 文件，内置了如 Tomcat、Jetty 或 Undertow 等 Web 服务器，无需外部 Servlet SpringBoot 提倡使用 Java 注解 来优化配置流程，简化了设置步骤。此外，它还包含了一些高级的监控和管控工具，特别是 Actuator 模块，它让开发者能够方便地追踪应用程序的运行状况和性能表现。这些特点使得 SpringBoot 成为开发微服务和云应用的优选，同样适用于企业级应用。
1.2 Vue框架
Vue 是一款专为构建动态和响应式的用户界面而设计的渐进式前端框架。Vue 在与一些更为庞大和全面的框架相比之中以其轻量级和模块化的特性脱颖而出，它的核心专注于视图层的构建，这样降低学习曲线的同时也便于与现有的项目或库进行无缝集成。 Vue 的设计理念强调简洁性和实用性，使开发者可以逐步地将框架的功能集成到项目中，不管是构建小型的交互界面还是处理大型应用，Vue 均能提供强大的功能支持。这种灵活性和易用性使前端开发更加高效和灵活，也是 Vue 受到广泛欢迎的关键因素之一。
1.3 MySQL数据库
MySQL 数据库是一个使用 SQL 作为查询语言的开源关系型数据库管理系统。这个系统一开始是 MySQL AB 公司所开发的，之后经历了 Sun Microsystems 的收购，最终成为 Oracle 公司旗下的产品。MySQL 因其出色的性能、可靠性和用户友好的特性而受到青睐，正因如此它也被广泛地应用于网站开发、数据存储解决方案和企业级软件系统中。它不但支持多种操作系统，而且还功能丰富且配置灵活，基本上都能满足从小型应用到大型数据仓库的需求，也正因如此是众多开发者和企业第一个选择的数据库解决方案。
2、数据库实体设计
设计数据库，需要按照设计的流程进行，首先还是要根据需求完成实体的确定，分析实体具有的特征，还有对实体间的关联关系进行确定。最后才是使用E-R模型的表示方法，绘制本系统的E-R图。不管是使用亿图软件，还是Visio工具，对于E-R模型的表示符号都一样，通常矩形代表实体，实体间存在的关系用菱形符号表示，实体的属性也就是实体的特征用符号椭圆表示。最后使用直线将矩形，菱形和椭圆等符号连接起来。接下来就开始对本系统的E-R图进行绘制。
（1）下图是用户实体和其具备的属性。
（2）下图是公告信息实体和其具备的属性。
（3）下图是购物车实体和其具备的属性。
（4）下图是商品实体和其具备的属性。
（5）下图是商家实体和其具备的属性。
（6）下图是商品收藏实体和其具备的属性。
（7）下图是商品评价实体和其具备的属性。
（8）下图是商品订单实体和其具备的属性。
（9）下图是收货地址实体和其具备的属性。
3、数据库表设计（展示部分表）
