Abstract
With the rapid development of information on the Internet, paperless homework
has become a trend. In response to this problem, a website specially adapted to
the form of communication between teachers and students has been developed. This
article introduces the whole development process of the course Q&A system. By
analyzing the needs of enterprises for the course answering system, a program
of computer management course answering system was created. The article
introduces the system analysis part of the course question answering system,
including feasibility analysis, etc. The system design part mainly introduces
the system function design and database design.
The question answering system of this course has three roles: administrator,
teacher, and student. The administrator functions include personal center,
student management, teacher coming, subject type management, student question
management, teacher answer management, teacher information management, watch
list management, communication area, system management. Student functions
include personal center, subject type management, student question management,
teacher answer management, teacher information management, watch list management,
and my collection management. Teacher functions include personal center, teacher
answer management, teacher information management, watch list management, and
my collection management. So it has a certain practicability.
This site is a B/S model system, using Spring Boot framework as the back-end
development technology, front-end framework is VUE, MYSQL database design and
development, fully guarantee the stability of the system. The system has the
characteristics of clear interface, simple operation and complete functions,
which makes the management of the course answering system systematic and
standardized.
Keywords:Course question answering system; Spring Boot framework; MYSQL
database; VUE framework

1 系统概述
1.1 研究背景
如今互联网高速发展,网络遍布全球,通过互联网发布的消息能快而方便的传播到
世界每个角落,并且互联网上能传播的信息也很广,比如文字、图片、声音、视频等。
从而,这种种好处使得互联网成了信息传播的主要途径,社会上各种各样的信息都想尽
办法通过互联网进行传播,互联网对社会产生的影响越来越大。
随着计算机技术的发展以及计算机网络的逐渐普及,互联网成为人们查找信息的重
要场所,二十一世纪是信息的时代,所以信息的交换和信息流通显得特别重要。因此,
开发合适的课程答疑系统成为企业必然要走的一步棋。开发合适的课程答疑系统,可以
方便管理人员对课程答疑系统的管理,提高信息管理工作效率及查询效率,有利于更好
的为用户提供服务。
1.2 研究目的
随着互联网技术的快速发展,网络时代的到来,网络信息也将会改变当今社会。各
行各业在日常企业经营管理等方面也在慢慢的向规范化和网络化趋势汇合。课程答疑系
统的信息化程度体现在将互联网与信息技术应用于经营与管理,以现代化工具代替传统
手工作业。无疑,使用网络信息化管理使信息管理更先进、更高效、更科学,信息交流
更迅速。
课程答疑还用普通的面对面交流,已经很落伍了,这样会导致了效率低下。而且,
时间一长的话,积累下来的数据信息不容易保存,对于查询、更新还有维护会带来不少
问题。对于数据交接也存在很大的隐患。如果采用电子化的存储方式就会带来很大的改
善,而且给用户的查询带来了很大便利,因此设计一个课程答疑系统刻不容缓,能够提
高企业在信息技术方面的展示水平。
1.3 系统设计思想
一个成功的网站应明确建设网站的目的,确定网站的功能,确定网站规模、投入费
用,进行必要的市场分析等。只有详细的策划,才能避免在网站建设中出现的很多问题,
使网站建设能顺利进行。同时,一个大型的计算机网站系统,必须有一个正确的设计指
导思想,通过合理选择数据结构、网络结构、操作系统以及开发环境,构成一个完善的
