【摘要】：教育改革的不斷深化,我國的教學和科研水平得到了極大的發(fā)展。隨著網(wǎng)絡技術的不斷發(fā)展,傳統(tǒng)的單一線下教學和科研方式顯然已經(jīng)不能適應時代的需求。因此,在網(wǎng)上進行教學科研管理必然成為發(fā)展趨勢。近年來,線上教學科研發(fā)展正如火如荼的開展,但是存在網(wǎng)站內(nèi)容針對性不強、網(wǎng)站結(jié)構不清晰、師生交流不及時等問題。本文在參考國內(nèi)外研究成果的基礎上,結(jié)合我們國家教學科研特點和自身教學實踐,進一步整合網(wǎng)站結(jié)構,使其更加符合學生學習習慣和教師教學科研使用習慣,并加入即時通信,讓師生溝通更加便捷,加入和配置SSL協(xié)議,增強系統(tǒng)安全性,最后考慮到網(wǎng)站的可擴展性,分析了服務器負載均衡,以適應未來高并發(fā)需求。本系統(tǒng)基于B/S實現(xiàn)教學科研管理功能,主要采用java語言,在MyEclipse平臺進行開發(fā)設計,服務器采用tomcat7.0,數(shù)據(jù)庫采用SqlServer,用到的框架主要包括bootstrap、easy—UI和jfinal。本系統(tǒng)分為三大部分開發(fā),即網(wǎng)頁前端開發(fā)、后臺管理系統(tǒng)開發(fā)和服務器開發(fā),主要實現(xiàn)以下幾個功能模塊:信息模塊、教學模塊、科研模塊、留言和在線答疑模塊、權限管理模塊、賬號管理模塊和輔助功能模塊。本文的主要難點一方面是實現(xiàn)即時通信,本文采用基于HTTP的長連接技術,是目前在純?yōu)g覽器環(huán)境下進行即時通信類應用開發(fā)的理想選擇,另一方面要配置SSL協(xié)議,對代碼編寫和服務器技術有較高要求。本網(wǎng)站與目前的教學科研網(wǎng)區(qū)別主要是增加了及時通信并且引入了 SSL協(xié)議,網(wǎng)站內(nèi)容上更加注重網(wǎng)站布局結(jié)構和知識結(jié)構的優(yōu)化,使其更加符合學生使用和學習的習慣,改進了傳統(tǒng)教學科研網(wǎng)互動性差,結(jié)構安排不合理的缺陷,并且增強了系統(tǒng)的安全性,使得系統(tǒng)更易于擴展。經(jīng)過測試分析,本系統(tǒng)運行正常,符合用戶使用習慣,能夠作為學校教學和科研用戶的網(wǎng)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.
