计算机专业论文范文 摘 要 目前,Java 2平台有3个版本,它们是适用于小型设备和智能卡的Java 2平台Micro版(Java 2 Platform Micro Edition,J2ME)、适用于桌面系统的Java 2平台标准版(Java 2 Platform Standard Edition,J2SE)、适用于创建服务器应用程序和服务的Java 2平台企业版(Java 2 Platform Enterprise Edition,J2EE)。 J2EE是一种利用Java 2平台来简化企业解决方案中的与开发、部署和管理相关的复杂问题的体系结构。J2EE技术是一套面向企业应用的体系结构,我们可以将J2EE理解为J2SE(Java 2 平台的标准版)的扩展和延伸,J2EE的基础就是J2SE,J2EE不仅巩固了标准版中的许多优点,例如"编写一次、到处运行"的特性、方便存取数据库的JDBC API、CORBA技术以及能够在Internet应用中保护数据的安全模式等等,同时还提供了对 EJB(Enterprise JavaBeans)、Java Servlet API、JSP(Java Server Pages)以及XML技术的全面支持。其最终目的就是成为一个能够使企业开发者大幅缩短投放市场时间的体系结构。 J2EE体系结构提供了中间层集成框架,它是用来满足那些无需太多费用而又需要高可用性、高可靠性以及可扩展性的应用的需求。通过提供统一的开发平台,可以使开发者在使用J2EE开发多层应用时降低开发费用和复杂性,同时提供对现有应用程序集成强有力支持,完全支持Enterprise JavaBeans,有良好的向导支持打包和部署应用,添加目录支持,增强了安全机制,提高了性能。 Struts框架是一种非常优秀的框架,是基于J2EE的MVC应用框架,虽然从正式发布到现在已经有五年多的时间,随着该技术的逐步成熟,它已经越来越多地运用于企业平台之上,许多大型网站已成功地应用了Struts框架。本文在总结了Struts框架技术及其工作原理的基础上,结合“基于web的课件信息管理系统”这个项目,实现了系统各个模块的基本功能,这为今后更好的应用Struts框架提供了参考。 本文结合实际项目的设计与开发对Struts框架进行研究,对Struts框架及其工作原理进行了介绍。同时,对开发过程中所应用到的SERVLET,JSP,JAVA等技术作了相应的介绍,规范的软件开发流程介绍,以及软件工程基本思想及各阶段实现。 本文共分五个部分阐述了基于WEB的课件信息管理系统的结构和设计实现过程。 第一部分:介绍了J2EE发展过程中的两大阶段:Model 1 与Model 2,并分析两者的优缺点,对两者进行比较,指出Model2的优越性。从而说明使用基于Model2的Struts框架的优势。 第二部分:对Struts框架进行了介绍,阐述了框架的工作原理,并分析了Struts框架的优缺点。 第三部分:经过认真的调研,对系统的开发进行了全面的需求分析,通过对系统的业务流程图,用例模型,顺序图的描述与定义,确定了系统的总体流程 。 第四部分:通过“基于WEB的课件信息管理系统”为例,来说明如何设计基于Struts框架的Web应用,以及在Struts框架中应用自定义标签的具体实现过程。 第五部分:介绍了在这次项目中用到的一些技术,例如Struts中自定义标签等。 第六部分:对本次所做项目的一个总结。 关键词:J2EE, MVC, Struts Abstract At present, the platform of Java 2 have three editions,the first is J2ME-Java 2 Platform Mirco Edition used to the small equiment and integlligent card,the second is J2SE-Java 2 Platform Standard Edition used to desktop system,the third J2EE-Java 2 Platfrom Enterprise Edition is used to create application of sever and service. J2EE is kind of architecturewhich used to simplify the difficult which relevant of development. deployment and manament in enterprise solution. The basement of J2EE is the core of Java platform or the standard edition of Java 2. J2EE not only stabilize lots of excellence in standard edition,for example "write one time ,run everywhere",make the technique of the saving of database include JDBC API、CORBA and so on,as well as the safe mode of protect data in the application in Internet.It also provide the integrated sustainment for EJB(Enterprise JavaBeans)、Java ervlets API、JSP(Java Server Pages)as well as XML.It's ultima thule is become one architecture which can cut shorten the time to plunge into market for developer. J2EE provide the integrated architecture satisfy the application demand which is high usability、high stability as well as expansibility .Through provide the unify platform of exploit,J2EE make the expenditure of exploit application of multilayer as well as provide strength sustainment to application of already exist, integrated sustainment for Enterprise JavaBeans,having the better guide to sustain pack and dispose of application,the sustainment of insert category,strenghren the security,heighten the capability . The frame of Struts is a kind of real fair according to J2EE the MVC application frame, although from release to have already had time that five years have another till now formally, along with should be technical gradually mature, it has already been make use of in the business enterprise terrace more and more on, many large websites have already applied the frame of Struts successfully. This text combine" conference room book system" item in tallying up the Struts frame technique and it work the foundation of the principle, carrying out the basic function of the system each mold piece, this provided the reference for the better application Struts frame of aftertime. This text passes the design and developments of the actual item to carry on the research to the frame of Struts, working to the frame of Struts and it the principle carried on the introduction. At the same time, in the folio hair process the XML, SERVLET, JSP apply to, JAVA etc. technique made the simple introduction, and the software development process of norm introduction, the software engineering basic thought and each stage realizations. Part 1: introduce the two greatest stages within the J2EE development processes respectively: Model 1 with Model 2, and analytical both of merit and shortcoming, carry on the comparison to both, point out Model2 superior sex.Thus explain the usage according to the advantage of the Model2 frame of Struts. Part 2: carry on the introduction to the frame of Struts, elaborate the principle of Struts, and analyzed the merit and shortcoming of the frame of Struts. Part 3: After serious survey,making a comprehensive assay of requirement for the system.Confirming the whole flow through describing and defining the flow chart of business,model of case,chart of sequence. Part 4: pass" sourceware managing system based on Web" of the whole project as an example, explain how to design according to the Web application of the frame of Struts,and use user-defined tag-libs. Part 5: In this part introduced In ths project used technology, for example the taglibs and so on. Part 6: For this project to a summarize Keyword: J2EE , MVC, Struts 目 录 摘 要I AbstractIII 引 言1 第1章J2EE应用体系结构系结构4 1.1J2EE应用程序体系结构的发展4 1.1.1JSP Model14 1.1.2JSP Model25 1.1.3JSP Model1 与JSP Model2 的比较6 1.2Struts框架的介绍7 1.2.1Struts介绍7 1.2.2Struts工作原理8 1.2.3Struts框架的优缺点10 第2章需求分析11 2.1开发背景11 2.3 课件信息管理系统需求分析13 2.4 数据库描述14 2.4.1对SQL Server的介绍14 2.4.2本系统所设计的数据结构和数据项18 2.5 需求规格19 2.5.1 系统特性119 2.5.2系统特性220 2.6 性能需求21 第3章系统详细设计22 3.1系统环境22 3.2模块划分22 3.3 课件信息管理系统的设计23 第4章系统实现25 4.1用户登录25 4.2功能模块28 第5章测试32 第6章项目中应用到的技术介绍34 6.1遍历信息(Struts Logic标签)34 6.2修改功能34 第7章总结35 致 谢36 参考文献37 外文原文38 外文翻译46
