基于BPEL的动态服务组合体系结构的研究

静态服务和动态服务是Web服务的两种组成方式,但是目前主要采用的静态服务的方式有较大的局限性。鉴于此,本文探索性地提出了一种基于BPEL技术的动态服务组合体系架构,分析了该体系结构中的关键问题及解决策略,在具体的实现中采用了Dijkstra算法作为服务匹配组合的策略方法,通过具体的阐述说明了服务组合实现的请求、分解、组合、验证等几个方面的问题。

Research on Dynamic Service Composition Architecture Based on BPEL

Static services and dynamic services are two compositions of Web services, but the static services at present mainly take the form of a great limitation. In view of this situation, this paper attempts to put forward a framework for dynamic service composition system based on the technology of BPEL, analyzes the key problems of the system structure and their solutions. The Dijkstra algorithm is adopted as a service matching combination strategy to implement dynamic service composition system. Several aspects including service composition implementation request, decomposition, combination and verification problems are interpreted in detail.
