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。因为传统二手物品交易信息管理难度大，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二手物品交易管理系统，可以解决许多问题。

二手物品交易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、公告管理、商家管理、商品管理、用户咨询管理、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。

二手物品交易管理系统可以提高二手物品交易信息管理问题的解决效率，优化二手物品交易信息处理流程，保证二手物品交易信息数据的安全，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、JSP。

公告管理

?商家

?商品

?商品咨询

购物车

3.2 后台功能

管理员在商家管理界面中可以对界面中显示，可以对商家信息的商家状态进行查看，可以添加新的商家信息等。

?管理员在商品管理界面中查看商品种类信息，商品描述信息，新增商品信息等。

?管理员在用户咨询管理界面中新增用户咨询，可以删除用户咨询。

?管理员在公告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
