【摘要】：利用高效的信息化技術(shù)和先進的網(wǎng)絡(luò)平臺技術(shù)與高校教學(xué)和管理系統(tǒng)的高度融合,已經(jīng)被看成高等教育面向全面化發(fā)展的必要途徑之一,“信息化校園”必定會成為高等教育信息化發(fā)展的主流趨勢。目前社會上的網(wǎng)絡(luò)社交軟件存在著受眾群體廣泛,且信息分散不易收集,可信度和可靠性差等問題,缺少針對在校大學(xué)生的校園信息定制系統(tǒng)。學(xué)校內(nèi)部雖然有著例如校內(nèi)網(wǎng)站、公告、論壇等等信息發(fā)布與交流的平臺,但也存在著發(fā)布信息雜亂,信息分散不易收集等諸多問題,如瀏覽網(wǎng)頁信息具有成本高、數(shù)據(jù)流量大、響應(yīng)速度慢、針對性不強等缺點。本論文主要是針對大學(xué)生應(yīng)用來進行多模塊的定制,以此滿足大學(xué)生對各個方面信息需求,讓學(xué)生方便快捷的獲取想要了解的信息。為滿足高效大數(shù)據(jù)量存儲,故采用云計算平臺為數(shù)據(jù)存儲集群。本系統(tǒng)利用Hadoop云計算平臺在數(shù)據(jù)處理方面的優(yōu)勢為基礎(chǔ),共分數(shù)據(jù)采集、數(shù)據(jù)解析、數(shù)據(jù)存儲、服務(wù)端與Andriod系統(tǒng)的交互為四大功能模塊,實現(xiàn)了校園信息定制所需達到的各項功能。在數(shù)據(jù)采集模塊中采用Heritrix網(wǎng)絡(luò)爬蟲進行數(shù)據(jù)的采集;在數(shù)據(jù)解析模塊中采用HtmlParser對種子URL對應(yīng)到不同的XML抽取模板,從而提供節(jié)點配置信息,采集到網(wǎng)頁結(jié)構(gòu)中各項有效數(shù)據(jù)。在數(shù)據(jù)存儲模塊中采用MapReduce做為并行計算模式,建立在HDFS分布式文件系統(tǒng)上的HBase為存儲模式。以Hadoop云計算平臺為基礎(chǔ)架構(gòu),對校內(nèi)辦公信息、大學(xué)生就業(yè)與創(chuàng)業(yè)信息和考試通知等,實現(xiàn)了分布式存儲和運算。在服務(wù)端與Andriod系統(tǒng)交互模塊,采取的服務(wù)器端技術(shù)為Java,利用Struts2框架搭建Web服務(wù)器,實現(xiàn)服務(wù)端與手機端的數(shù)據(jù)交換。本文主要對校園信息定制系統(tǒng)的需求分析、系統(tǒng)的個性化定制要求與最終客戶端成果的呈現(xiàn)來驗證本套系統(tǒng)最終已經(jīng)完成當初的設(shè)計目標。該論文在云計算領(lǐng)域中,對于高校信息化處理的研究具有一定的實際意義。
[Abstract]:The highly integrated use of efficient information technology and advanced network platform technology with the teaching and management system in colleges and universities has been regarded as one of the necessary ways for the overall development of higher education. Information campus is bound to become the mainstream trend of the development of higher education informatization. At present, there are many problems in social network social software, such as wide audience group, difficult to collect information, poor credibility and reliability, and lack of campus information customization system for college students. Although there are many platforms for information dissemination and exchange, such as internal websites, announcements, forums, etc., there are still many problems, such as the disorderly distribution of information and the difficulty of collecting information, such as the high cost of browsing web information. Large data flow, slow response speed, weak pertinence and other shortcomings. This paper is mainly aimed at students should be used to customize the multi-module, so as to meet the information needs of college students in all aspects, so that students can easily and quickly get the information they want to know. In order to satisfy the high efficiency data storage, the cloud computing platform is used as the data storage cluster. Based on the advantages of Hadoop cloud computing platform in data processing, the system is divided into four functional modules: data acquisition, data analysis, data storage, and the interaction between the server and the Andriod system. Realized the campus information customization needs to achieve the various functions. In the data acquisition module, Heritrix network crawler is used to collect data, and HtmlParser is used in the data analysis module to correspond the seed URL to different XML extraction templates, so as to provide node configuration information and collect the effective data in the web page structure. In the data storage module, MapReduce is used as the parallel computing mode, and HBase based on the HDFS distributed file system is used as the storage mode. Based on Hadoop cloud computing platform, distributed storage and operation are realized for office information, college students' employment and entrepreneurship information, examination notice and so on. In the server and Andriod system interaction module, the server technology is Java, using Struts2 framework to build web server, realize the data exchange between server and mobile phone. This paper mainly analyzes the requirements of the campus information customization system, the personalized customization requirements of the system and the presentation of the final client results to verify that the system has finally completed the original design objectives. In the field of cloud computing, this paper has some practical significance for the research of information processing in colleges and universities.
