基于AOP的Web Services管理架构研究

RESEARCH ON AOP BASED WEB SERVICES MANAGEMENT ARCHITECTURE

W eb Services技术通过集成第三方W eb服务,可以极大提高企业级应用系统的开发效率。但是目前的大多数分布式应用中,客户端应用只能简单集成W eb Services,无法根据实际需求的变化动态管理W eb Services。本文讨论了几种不同的W eb Serv-ices管理架构,进一步给出了一种基于面向方面的编程技术AOP的W eb Services动态管理架构。采用这种架构,我们在客户端应用与W eb Services之间引入管理层,并且在管理层采用动态横切技术实现对W eb Services的管理。

Web Services technologies accelerate enterprise application development by allowing the integration of third-party Web Services. But most of current distributed systems just simply integrate the Web Services into the client side application. The client application can＇t manage the Web Services dynamically according to the requirement changes. In this paper ,several Web Services management architectures are discussed. Then we introduce an AOP-based architecture of Web Services dynamic management. A layer responsible for the management of Web Services designed between the client application and the real Web Services,and dynamic crosscutting are used to implement the management function of this laver.
