【摘要】 电子商务的蓬勃发展促使现代企业实体纷纷将业务模式由传统方式转为Internet方式，企业与其商务伙伴的商务进程也逐渐演变成彼此之间信息系统地直接对话；计算机技术的不断成熟使企业在构建信息系统的时候有了更多的选择，构建的系统干差万别，不同系统交互面临的环境是越来越复杂，成了电子商务进一步发展的瓶颈所在。 异构信息系统的不断增加，使各系统间的互操作性显得尤其必要。如何去动态地集成这些异构系统，使之能够无缝地进行通信，从而实现数据交换、信息共享，也就成了下一代互联网架构Web服务所要解决的主要问题。Web服务建立在完全开放的标准之上，可以被认为是基于Internet的组件开发模型，通过提供一种平台无关、语言无关、数据格式无关的Web访问接口，形成了一种在网络环境下，支持不同的系统平台、数据格式和编程语言的企业解决方案。 本文着重于如何采用Web服务去集成多个系统的交互应用。首先介绍了集成应用的需求以及国内外对此的研究；接着介绍了Web服务概念、模型、体系结构等内容；然后介绍了Web服务的主要应用技术，包括XML、SOAP、WSDL、UDDI；最后本文以一个B2B系统集成为例分析其Web服务解决方案。采用Microsoft的Visual硕士论文基于Web服务的集成应用研究studio.Net 2003来创建web服务，Java技术来实现Web服务的消费，探索了Java对.Net服务的访问以及SOAP消息的发送与接收。Java具有天生的平台无关性，可以部署在非诚ndows平台系统上，所以本论文实现的系统具有很好的跨平台操作能力，它的开发和实现再次验证了认飞b服务解决系统集成问题的优势所在。更多还原

【Abstract】 The booming development of the electronic commerce urge the modern business enterprise entity to change their business mode from traditional way to Internet way, therefore the business processes between the enterprises and its business partners are also gradually evolving into direct communication between the information system of each other; the continuous maturity of computer technology provides the enterprises with more and more choices when setting up their information system which results in the diversification of information system built. The environment for different systems to interact is becoming more and more complicated, and this is the bottleneck of further development of electronic commerce.The continuous increase of heterogeneous information systems makes the operability between them particularly necessary. How to dynamically integrate these heterogeneous systems and make them communicate seamlessly, realize the data exchange and share the information is the main issue which the next generation of internet structure - web service is going to resolve. Web service is based on entirely open standards and can be considered as the component development mode grounded on Internet. By providing a kind of platformindependent, language independents data format independent web access interface, it composes the business enterprise solution supporting different system platform , data format and program language under the environment of network.This issue puts great emphasis on how to adopt web service to integrate the multiply systems for operability. First it introduces the need of integrated application and the research work being done domestically and internationally; and then it introduces web service’s concepts modes architecture etc.; afterwards it focuses on the main technology constituting web service including XML, SOAP, WSDL and UDDI; Finally this paper ends up with a B2B system integration demonstration and analyzes the web service solution. Microsoft Visual Studio.Net is adopted to create web service and Java is used to consume web service. This paper investigates Java’s invocation of .Net web service and traces the sending and receiving of SOAP message. As Java has been born platform-independent, it can be deployed into non-Windows platform. As a result, the system developed in this paper has the good cross-platform operation ability; this verifies again that web service has the superior advantages to solve the issue of system integration.更多还原
