摘　　要：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。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.
