摘　　要：Web Services是目前解决Web环境下跨平台、跨语言、松耦合的分布式系统的最佳解决方案,但是作为SOA(Service-Oriented Architecture)应用的组成部分,Web Services中存在的一些横切关注点如授权、事务、安全性等降低了WebServices的适应性和重用性,构建的应用也难以维护和扩展。把面向方面的思想引入到Web Services中,将它的横切关注点分离出来单独实现为Aspectual Services,并在应用运行时在SOAP(Simple Object Access Protocol)消息层实现Web Services和Aspectual Services的编织来解决上述问题。Web Service is the best method to solve cross-platform, cross-language and loosely coupled distributed system in Web environment at present, but because of some crosscutting concerns in Web Services such as authorization, transaction, security, etc. , which are the constituents of SOA-applications, the adaptability and reuse of Web Services are reduced, and it is difficult to maintain and extend the SOA- application which is composed of them. In this paper, aspect - oriented programming is introduced to the Web Service, its crosscutting concerns are separated and realised individually as Aspectual Services, and the problems addressed above are to be solved by a Weaver weaving Web services and Aspectual Services at SOAP message layer when the application runs.

关 键 词：Web SERVICES SOA 横切关注点 面向方面编程
