【摘要】：互聯(lián)網(wǎng)技術的高速發(fā)展正在不斷地改變?nèi)藗兊纳詈凸ぷ鞣绞?也在改變著人們的信息搜索方式。自從1998年Google問世以來,搜索引擎已逐漸成為人們獲取信息的主要方式。幾乎每一個上過網(wǎng)的用戶都使用過搜索引擎,隨著使用搜索引擎人數(shù)增多,搜索引擎已經(jīng)成為一種重要的媒體。沈陽地鐵有限公司是承擔沈陽市城市快速軌道交通建設和運營管理的大型國有獨資公司,它順應時代的潮流和網(wǎng)站業(yè)務的需求,研發(fā)了自己的搜索引擎。 本文設計和實現(xiàn)的搜索引擎系統(tǒng),是專門針對沈陽地鐵公司特點而為公司量身定做的,因為這個軟件主要在公司門戶和內(nèi)部網(wǎng)站上使用,需要發(fā)布到公司的Intranet上,所以開發(fā)模式?jīng)]有選擇C/S模式而是選擇了B/S模式,開發(fā)語言選擇了Java和JSP,最終的程序運行在Windows Server2008平臺下。 本文首先介紹了搜索引擎系統(tǒng)的特點和功能,對搜索引擎系統(tǒng)進行了概述,比較分析了當前國內(nèi)外搜索引擎系統(tǒng)的研究現(xiàn)狀及目前商業(yè)系統(tǒng)的不足,進一步研究了J2EE框架在開發(fā)搜索引擎系統(tǒng)中的應用,給出了系統(tǒng)的整體設計方案。在對公司搜索需求分析的基礎上,完成了系統(tǒng)的總體設計,并闡述了系統(tǒng)的設計原則、構建思想、具體模塊設計,進而對系統(tǒng)的核心模塊進行了詳細設計和實現(xiàn)。最后著重分析了系統(tǒng)實現(xiàn)過程中所遇到的技術與理論難題,涉及到了J2EE Web應用開發(fā)前后臺技術、Struts框架、Hibernate數(shù)據(jù)訪問技術、Spring框架等。本系統(tǒng)采用了典型三層B／S架構,即將實現(xiàn)部分劃分為表示層、數(shù)據(jù)訪問層和業(yè)務邏輯層。在系統(tǒng)實現(xiàn)過程中嚴格遵守沈陽地鐵有限公司技術部的編碼規(guī)范、開發(fā)流程,充分運用面向?qū)ο蟮脑O計思想和MVC等設計模式；充分發(fā)揮了MyEclisep for Spring9.1開發(fā)平臺為開發(fā)者提供的設計、編碼和測試工具。文中最終實現(xiàn)的系統(tǒng)已經(jīng)實際用于公司的門戶網(wǎng)站和內(nèi)部網(wǎng)站之上,達到了預期的項目要求,該項目目前仍在繼續(xù)完善其自身功能。
[Abstract]:The rapid development of Internet technology is constantly changing the way people live and work, and also changing the way people search for information. Since Google came out in 1998, search engine has gradually become the main way to get information. Almost every user on the web has used a search engine. With the increase in the number of people using search engine, search engine has become an important media. Shenyang Metro Co., Ltd. is a large state-owned sole proprietorship company which is responsible for the construction and operation management of Shenyang City Rapid Rail Transit. It has developed its own search engine in line with the trend of the times and the demand of website business. The search engine system designed and implemented in this paper is tailor-made for Shenyang Metro Corporation because it is mainly used on company portals and internal websites and needs to be published on the company's Intranet. So the development mode does not choose the C / S mode but the B / S mode, the development language chooses Java and JSP, and the final program runs under the Windows Server2008 platform. This paper first introduces the characteristics and functions of search engine system, summarizes the search engine system, compares and analyzes the current research situation of search engine system at home and abroad and the deficiency of current commercial system. The application of J2EE framework in the development of search engine system is further studied, and the overall design scheme of the system is given. On the basis of the analysis of the company's search requirements, the overall design of the system is completed, and the design principle, construction idea and specific module design of the system are expounded, and then the core modules of the system are designed and implemented in detail. Finally, the paper analyzes the technical and theoretical problems encountered in the implementation of the system, including the J2EE Web application development technology, Struts framework, hibernate data access technology and so on. The system uses a typical three-tier B / S architecture, which is divided into presentation layer, data access layer and business logic layer. In the implementation of the system, strictly abide by the code specification of the technical department of Shenyang Metro Co., Ltd., develop the flow, make full use of the object-oriented design thought and MVC design pattern, give full play to the design provided by the MyEclisep for Spring9.1 development platform for the developer. Coding and testing tools. The system implemented in this paper has been used on the company's portal and internal website, which meets the expected project requirements, and the project is still improving its own function.
