1、项目介绍及开发技术

1.1 项目介绍

       如今社会上各行各业，都喜欢用自己行业的专属软件工作，互联网发展到这个时候，人们已经发现离不开了互联网。新技术的产生，往往能解决一些老技术的弊端问题。因为传统宠物商城网站系统信息管理难度大，容错率低，管理人员处理数据费工费时，所以专门为解决这个难题开发了一个宠物商城网站系统管理系统，可以解决许多问题。

        宠物商城网站系统管理系统按照操作主体分为管理员和用户。管理员的功能包括收货地址管理、购物车管理、字典管理、宠物论坛管理、公告信息管理、商家管理、商品管理、商品收藏管理、商品评价管理、商品订单管理、用户管理、管理员管理。用户的功能等。该系统采用了Mysql数据库，Java语言，Spring Boot框架等技术进行编程实现。

        宠物商城网站系统管理系统可以提高宠物商城网站系统信息管理问题的解决效率，优化宠物商城网站系统信息处理流程，保证宠物商城网站系统信息数据的安全，它是一个非常可靠，非常安全的应用程序。

1.2 开发技术

Java开发语言、SpringBoot、MyBatisPlus、MySQL数据库、Maven、IDEA开发工具、JDK1.8+、Vue、HTML、CSS、JS。

3、功能截图

商品管理：管理员在商品管理界面中可以对界面中显示，可以对商品信息的商品状态进行查看，可以添加新的商品信息等。

商品订单管理： 管理员在商品订单管理界面中查看商品订单种类信息，商品订单描述信息，新增商品订单信息等。

公告管理： 管理员在公告管理界面中新增公告，可以删除公告。

公告管理类型： 管理员在公告类型管理界面查看公告的工作状态，可以对公告的数据进行导出，可以添加新公告的信息，可以编辑公告信息，删除公告信息。

4、数据库表结构设计
