【摘要】：互联网技术的高速发展正在不断地改变人们的生活和工作方式,也在改变着人们的信息搜索方式。自从1998年Google问世以来,搜索引擎已逐渐成为人们获取信息的主要方式。几乎每一个上过网的用户都使用过搜索引擎,随着使用搜索引擎人数增多,搜索引擎已经成为一种重要的媒体。沈阳地铁有限公司是承担沈阳市城市快速轨道交通建设和运营管理的大型国有独资公司,它顺应时代的潮流和网站业务的需求,研发了自己的搜索引擎。本文设计和实现的搜索引擎系统,是专门针对沈阳地铁公司特点而为公司量身定做的,因为这个软件主要在公司门户和内部网站上使用,需要发布到公司的Intranet上,所以开发模式没有选择C/S模式而是选择了B/S模式,开发语言选择了Java和JSP,最终的程序运行在Windows Server2008平台下。本文首先介绍了搜索引擎系统的特点和功能,对搜索引擎系统进行了概述,比较分析了当前国内外搜索引擎系统的研究现状及目前商业系统的不足,进一步研究了J2EE框架在开发搜索引擎系统中的应用,给出了系统的整体设计方案。在对公司搜索需求分析的基础上,完成了系统的总体设计,并阐述了系统的设计原则、构建思想、具体模块设计,进而对系统的核心模块进行了详细设计和实现。最后着重分析了系统实现过程中所遇到的技术与理论难题,涉及到了J2EE Web应用开发前后台技术、Struts框架、Hibernate数据访问技术、Spring框架等。本系统采用了典型三层B／S架构,即将实现部分划分为表示层、数据访问层和业务逻辑层。在系统实现过程中严格遵守沈阳地铁有限公司技术部的编码规范、开发流程,充分运用面向对象的设计思想和MVC等设计模式；充分发挥了MyEclisep for Spring9.1开发平台为开发者提供的设计、编码和测试工具。文中最终实现的系统已经实际用于公司的门户网站和内部网站之上,达到了预期的项目要求,该项目目前仍在继续完善其自身功能。
[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.
