【摘要】：教育改革的不断深化,我国的教学和科研水平得到了极大的发展。随着网络技术的不断发展,传统的单一线下教学和科研方式显然已经不能适应时代的需求。因此,在网上进行教学科研管理必然成为发展趋势。近年来,线上教学科研发展正如火如荼的开展,但是存在网站内容针对性不强、网站结构不清晰、师生交流不及时等问题。本文在参考国内外研究成果的基础上,结合我们国家教学科研特点和自身教学实践,进一步整合网站结构,使其更加符合学生学习习惯和教师教学科研使用习惯,并加入即时通信,让师生沟通更加便捷,加入和配置SSL协议,增强系统安全性,最后考虑到网站的可扩展性,分析了服务器负载均衡,以适应未来高并发需求。本系统基于B/S实现教学科研管理功能,主要采用java语言,在MyEclipse平台进行开发设计,服务器采用tomcat7.0,数据库采用SqlServer,用到的框架主要包括bootstrap、easy—UI和jfinal。本系统分为三大部分开发,即网页前端开发、后台管理系统开发和服务器开发,主要实现以下几个功能模块:信息模块、教学模块、科研模块、留言和在线答疑模块、权限管理模块、账号管理模块和辅助功能模块。本文的主要难点一方面是实现即时通信,本文采用基于HTTP的长连接技术,是目前在纯浏览器环境下进行即时通信类应用开发的理想选择,另一方面要配置SSL协议,对代码编写和服务器技术有较高要求。本网站与目前的教学科研网区别主要是增加了及时通信并且引入了 SSL协议,网站内容上更加注重网站布局结构和知识结构的优化,使其更加符合学生使用和学习的习惯,改进了传统教学科研网互动性差,结构安排不合理的缺陷,并且增强了系统的安全性,使得系统更易于扩展。经过测试分析,本系统运行正常,符合用户使用习惯,能够作为学校教学和科研用户的网站使用。
[Abstract]:With the deepening of the educational reform, the teaching and scientific research level of our country has been greatly developed. With the development of the network technology, the traditional single-line offline teaching and scientific research methods have obviously not been able to meet the needs of the times. Therefore, on-line teaching and research management must be the developing trend. In recent years, the development of online teaching and research is such as the development of the fire, but there are problems such as the lack of the content of the website, the unclear structure of the website, the non-timely communication between the students and the students. On the basis of reference to the domestic and foreign research results, this paper, in the light of the characteristics of our country's teaching and scientific research and its own teaching practice, further integrates the structure of the website, so that it is more in line with the students' learning habit and the use habit of the teaching and research of the teacher, and the instant communication is added, so that the communication between the students and the students is more convenient, Add and configure the SSL protocol, enhance the security of the system, and finally take into account the extensibility of the website, and analyze the load balance of the server to meet the high concurrent requirements of the future. This system implements the function of teaching and research management based on B/ S, mainly adopts java language, develops and designs on the MyEclipse platform, the server adopts tomcat7.0, the database adopts SqlServer, and the framework used mainly includes bootstrap, easy, UI and jfinal. The system is divided into three parts, namely, the front end development of the web page, the development of the background management system and the server development, and mainly realizes the following functional modules: an information module, a teaching module, a scientific research module, a message and an on-line answering module and a rights management module, The account management module and the auxiliary function module. The main difficulty of this paper is to realize instant communication. In this paper, an HTTP-based long-connection technology is adopted, which is an ideal choice for the application and development of instant messaging in a pure browser environment. On the other hand, the SSL protocol is to be configured, and the code writing and server technology have higher requirements. The main difference between this website and the current teaching and research network is to increase the timely communication and introduce the SSL protocol. The content of the website is more focused on the optimization of the layout structure and the knowledge structure of the website, so that it is more in line with the habit of the students to use and study, and improves the interactive difference of the traditional teaching and research network. The structure arrangement is not reasonable, and the security of the system is enhanced, so that the system is more easily expanded. After the test and analysis, the system runs normally and meets the user's using habit and can be used as the website of the school teaching and scientific research user.
