设计题目：二手车交易网站的设计与实现
I
摘 要
网络技术和计算机技术发展至今，已经拥有了深厚的理论基础，并在现实中
进行了充分运用，尤其是基于计算机运行的软件更是受到各界的关注。加上现在
人们已经步入信息时代，所以对于信息的宣传和管理就很关键。因此二手车交易
信息的管理计算机化，系统化是必要的。设计开发二手车交易网站不仅会节约人
力和管理成本，还会安全保存庞大的数据量，对于二手车交易信息的维护和检索
也不需要花费很多时间，非常的便利。
二手车交易网站是在 MySQL 中建立数据表保存信息，运用 SSM 框架和
Java 语言编写。并按照软件设计开发流程进行设计实现。系统具备友好性且功能
完善。管理员管理汽车和汽车品牌，管理汽车资讯和用户留言，管理不同状态的
订单。用户查看汽车资讯，收藏汽车，评论汽车，购买汽车，查看不同状态的订
单。
二手车交易网站在让二手车交易信息规范化的同时，也能及时通过数据输入
的有效性规则检测出错误数据，让数据的录入达到准确性的目的，进而提升二手
车交易网站提供的数据的可靠性，让系统数据的错误率降至最低。

Abstract
Network technology and computer technology have developed so far, they
already have a solid theoretical foundation and have been fully used in reality,
especially the software based on computer operation has attracted the attention of all
walks of life. In addition, now that people have entered the information age, the
promotion and management of information is very important. Therefore, it is
necessary to computerize and systemize the management of used car transaction
information. The design and development of a used car trading website will not only
save manpower and management costs, but also store a huge amount of data safely,
and it will not take a lot of time to maintain and retrieve used car transaction
information, which is very convenient.
The second-hand car trading website is to establish a data table in MySQL to
save the information, using the SSM framework and Java language to write. And in
accordance with the software design and development process for design and
implementation. The system is friendly and fully functional. The administrator
manages cars and car brands, manages car information and user messages, and
manages orders in different states. Users view car information, favorite cars, comment
on cars, buy cars, and view orders in different states.
While standardizing used car transaction information, the used car trading
website can also detect incorrect data in time through the validity rules of data input,
so that the data entry can achieve the purpose of accuracy, thereby improving the
reliability of the data provided by the used car trading website Performance, which
minimizes the error rate of system data.
Key Words：Used car trading website; MySQL; SSM framework
