Web服务客户端自动生成器模型的研究与实现
摘要
Web服务是当今IT业界的焦点所在。Web服务的主要目标就是在现有的各种异构平台的基础上构筑一个通用的与平台无关、语言无关的技术层，各种不同平台之上的应用依靠这个技术层来实施彼此的动态组合和集成。Web服务是实现动态电子商务所必须的技术架构。
为了实现动态电子商务的快速整合和普通个人用户对Web服务的便捷使用，本文在对Web服务技术的深入探讨之后，提出了Web服务客户端自动生成器模型，并对其设计及实现进行了详细地描述。
首先介绍了Web服务的概念及其体系结构，详细分析和探讨了构建Web服务的核心技术：SOAP、WSDL、UDDI；然后，提出了Web服务客户端自动生成器模型的总体结构，分别对其组成的三大模块（UDDI查找模块、WSDL解析模块和用户操作调用模块）进行框架设计，同时也介绍了模型实现所采用的技术和开发平台。根据不同的业务需要，本模型有纯Java版和Web版两种实现方案，分别为普通个人Web服务的个性化访问和动态电子商务用户的快速集成所服务；接着深入解析模型详细设计中的细节，给出相应源程序进行分析；最后，全文对Web服务客户端自动生成器模型的设计及其实现进行总结，并分析本模型尚存的一些不足，指出了在日后工作中需要解决的问题。
Web services is the focus of IT fields today. The goal of Web services is to provide a common technology layer which has no relation with language and platform. The application of different platforms needs this technology layer to connect and integrate dynamically with each other. Web services becomes the necessary technology architecture of the realization of dynamic e-business.
To realize the quick integration of dynamic e-business and the easy operation of Web services for personal users, this paper discusses Web services technologies，states a designing scheme of Web Services Client Auto-generated Tool(WSCAT) and describes its design and realization in detail.
Firstly，this paper introduces the concept and the architecture of Web services，analyzes the core technologies to construct Web services，SOAP，WSDL and UDDI，in detail. Secondly it states the architecture of WSCAT and designs its three components (UDDI finding model, WSDL analyzing model and user operating model) respectively. At the same time, this paper also describes the technologies and developing platforms of WSCAT. According to the different demands, there are two realization versions of WSCAT, pure Java version and Web version. The former is used for the personal users to access Web Services by PC. The latter is designed for personal users and users of dynamic e-business. Thirdly this paper analyzes the details of the three models and the corresponding source programs. In the end， it summarizes the WSCAT model and analyzes its shortcomings. And also it gives out some aspects which need to be solved in further work.
