【摘要】 随着计算机技术的发展,基于客户机/服务器(C/S)模式的企业信息系统取得了较多的成功应用。然而随着近年来Internet的迅速发展和Internet技术的广泛应用,传统的客户机/服务器模式已经明显不能适应企业应用的发展需求,同时基于B/S模式的多层系统自身具有的良好扩展性,使得越来越多的企业信息系统已经开始由原来的客户机/服务器结构向多层结构转化。正是在这样的一个背景下,Sun公司提出了J2EE平台。J2EE是一种利用Java2平台来简化企业解决方案的开发、部署和管理相关的复杂问题的体系结构。J2EE体系结构提供中间层集成框架用来满足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。本文以扬州万方电子技术有限公司企业信息系统的构建为背景,从应用系统的总体结构入手,结合设计模式的思想对整个系统的构架进行了详细的分析,并在此基础之上讲述了系统的公用Web查询模块的实现机制。通过对公用Web查询模块实现机制的分析,说明了把XML和设计模式的思想应用于J2EE系统中,能有效地提高系统的可扩展性以及和其他系统之间的交互性,为今后企业信息系统的构建提供了借鉴。更多还原

【Abstract】 With the development of computer technology, the enterprise information system based on Client/Server architecture has made success during these years. But with the development of Internet and the widely use of Internet technology, The traditional C/S architecture can’t meet the needs of enterprise’s development, and the Multi-layer structures based on B/S architecture have better in reusability and extensibility, so more and more enterprise information system move to Multi-layer structure. Just under such a background, Sun Microsystem Inc. provides J2EE platform for that requirement. The J2EE platform is an architecture which is used to simplify the complication of development, deployment and management of enterprise solutions, and supplies middle-tier integrated framework to satisfy the requirement which needs a little cost but high availability, high reliability and extensibility.This thesis takes the construction of WanFang enterprise’s information system as background, introducing the architecture of the application and analysis the framework of the system using design patterns, then researches the public Web query module. With those analyses, we can get the conclusion that systematic expansibility and interaction of other systems can be improved effectively by applying XML and design pattern to J2EE system. Those methods also offer reference for the construction of enterprise information system in the future.更多还原
