题目：二手物品交易的设计与实现
摘 要
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。

Abstract
Nowadays, all walks of life in society like to work with their own
industry-specific software. At this point in the development of the Internet, people
have found that they cannot do without the Internet. The emergence of new
technologies can often solve the drawbacks of some old technologies. Because the
traditional personnel information management is difficult, the fault tolerance rate is
low, and the management personnel is labor-intensive and time-consuming to process
data, a personnel management system has been specially developed to solve this
problem, which can solve many problems.
The personnel management system is divided into administrators and users
according to the operating subjects. The functions of the administrator include
managing employees, managing personnel information, including recruitment
management, training management, reward and punishment management, salary
management, etc., and can manage operators. User functions include managing
department and department position information, managing recruitment information,
training information, salary information, etc. The system uses Mysql database, Java
language, Spring Boot framework and other technologies for programming.
The personnel management system can improve the efficiency of solving
personnel information management problems, optimize the personnel information
processing process, and ensure the security of personnel information data. It is a very
reliable and very safe application.
