题目：社区团购系统设计与实现
I
摘 要
使用旧方法对社区团购信息进行系统化管理已经不再让人们信赖了，把现在
的网络信息技术运用在社区团购信息的管理上面可以解决许多信息管理上面的
难题，比如处理数据时间很长，数据存在错误不能及时纠正等问题。
这次开发的社区团购系统有管理员，用户和商家。管理员功能有个人中心，
用户管理，商家管理，商品分类管理，商品团购管理，团购公告管理，留言板管
理，系统管理，订单管理等。商家可以发布商品，处理订单。用户可以注册登录
团购商品，查看信息等操作。
经过前面自己查阅的网络知识，加上自己在学校课堂上学习的知识，决定开
发系统选择 B/S 模式这种高效率的模式完成系统功能开发。这种模式让操作员基
于浏览器的方式进行网站访问，采用的主流的 Java 语言这种面向对象的语言进
行社区团购系统程序的开发，在数据库的选择上面，选择功能强大的 MySQL 数
据库进行数据的存放操作。
社区团购系统被人们投放于现在的生活中进行使用，该款管理类软件就可以
让管理人员处理信息的时间介于十几秒之间。在这十几秒内就能完成信息的编辑
等操作。有了这样的管理软件，社区团购信息的管理就离无纸化办公的目标更贴
近了。

Abstract
Using the old method to systematically manage community group buying information
is no longer trusted by people. Applying the current network information technology
to the management of community group buying information can solve many problems
in information management, such as a long time to process data. There are problems
such as errors that cannot be corrected in time.
The community group buying system developed this time has administrators, users
and merchants. Administrator functions include personal center, user management,
business management, commodity classification management, commodity group
purchase management, group purchase announcement management, message board
management, system management, order management, etc. Merchants can publish
products and process orders. Users can register for group purchase products, view
information and other operations.
After the network knowledge I checked before, plus the knowledge I learned in the
school classroom, I decided to choose the B/S mode as a high-efficiency mode for the
development system to complete the system function development. This mode allows
operators to access the website based on a browser. The mainstream Java language, an
object-oriented language, is used for the development of community group buying
system programs. In the selection of databases, a powerful MySQL database is
selected for data analysis. Storage operation.
The community group buying system is used by people in their daily lives. This
management software allows managers to process information within a dozen seconds.
Information editing and other operations can be completed within these ten seconds.
With such management software, the management of community group buying
information is closer to the goal of paperless office.
Key Words：Community group buying system; Java; MySQL; SSM framework
