本科毕业(论文)设计 J2EE技术 给Web应用程序的开发.doc

摘 要 在今天,J2EE技术 [1]给Web应用程序的开发提供了非常灵活的选择。如何把这些技术组合起来形成一个适应项目需要的稳定架构是项目开发过程中一个非常重要的步骤。长期以来,Java开发者致力于找到一种完美的Web层应用框架,从而规范这一层软件的开发。本文结合易通国际货运代理公司信息管理系统项目，介绍了Struts 框架的体系结构和工作原理，并给出了的实现。 MVC设计模式。然后文章介绍了Struts框架的体系结构和工作原理,然后结合项目实例,进行具体代码分析。MVC是Model(模型)、View(视图)、Controller(控制)的缩写，MVC是适用于大型WEB应用开发的架构技术，其目的是最大限度的降低系统各部分之间的耦合性，增强系统的可扩展维护性，提高代码重用率。本文结合了MVC设计模式，说明了Struts的体系结构，讲述了Struts实现MVC模式Web应用的过程。在应用实例中，讲述了一个简单的Struts程序要展示的内容，以及为完成这个程序需要创建的文件；然后对这些文件的内容，即源代码，进行具体分析，最后还叙述了这个实例的工作过程。 研究了易通国际货运代理公司的组织结构和业务流程，结合B/S结构和Struts框架的特点和优势，提出了系统实现方案。 关键词：J2EE，MVC，struts，框架 Abstract Today, J2EE technology has provided very flexible choice for development of Web application program. It is the project how to combine the technology to transform into a steady framework of meeting the needs of project to develop a very important step in course. For a long time, Web layer of application frame that it is perfect that Java developer is devoted to finding one kind of, thus standardize the development of web layer of software. This text combines the item of ET`s MIS, introduce system structure of Struts frame and operation principle , and the realization providing its customers information and registering. The article has introduced the relevant knowledge about model of WEB application program at first, among them has recommended especially that MVC . Then the article has introduced system structure of Struts frame and operation principle, then combine the project , carry on concrete code analysis. MVC is the abbreviations of Model (model ) , View (view ) , Controller (controls ), MVC is the framework technology which is suitable for large-scale WEB development, its purpose is coupling between every part of a maximum reducing system, can strengthen a systematic one expansion maintaining , raise the putting of codes in an position rate. This text has combine MVC , has stated the system structure of Struts, have told that Struts realizes the course of MVC. In the instance, has told a content
