Client/Server模式的传统服务的Web Service包装器的研究

Study on Web Service Wrapper on Wrapping Client/Server's Traditional Services

基于Web服务实现企业间应用集成是网络经济模式的发展趋势.针对企业中累积的大量的基于Client/Server架构的应用系统(简称传统服务)进行研究,提出了一种将传统服务包装为WebService的实现方法;利用.NET平台的反射(Reflect)和代码树(CodeDom)等特性,自动地实现字节流与XML元数据的转换,有效地实现了传统服务的集成;从易访问性、可维护性、可集成性、安全性、服务质量五个方面分别对传统服务和包装后的WebService进行了对比评价,为实现紧密耦合系统到松散耦合系统的映射提供了可靠的基础.

It is the trend that implementing application integration among enterprises based on Web services. According to the study on lots of existed Client/Server application (or named traditional service), a realizing method of wrapping traditional services into Web services is presented. Adopting the property of.NETs Reflect and CodeDom, the transform between byte steam and XML metadata is implemented automatically, and realizing the integration of traditional services. By comparison of traditional service and Web service wrapped on five aspects of access easily, maintainability, integration, security and quality of service, it provides reliable foundation for realizing the mapping from tightly-coupled to loosely-coupled application.
