摘要
随着Web Services及其相关技术的成熟,软件开发逐渐从基于构件的软件开发转向基于服务的软件开发。因此如何支持适应用户需求的Web Services的组装是当前研究的热点之一。本文提出了一种支持领域变化性的WebServices组装方法,该方法可以较好地适应用户需求的更改。文中引入了领域组装模型,使之能对一族具有领域共性和变化性的系统进行定义与描述。接着论述了如何根据用户的需求来确定Web Services应用的系统组装模型,并转换为可执行的组装描述语言的过程和方法。本文在最后给出了一个应用实例。
With the development of Internet and the technology of Web services,more and more applications have changed the way to develop,that is from component-based software development to service-based software develop- ment. This paper puts forward a method of Web services composition to support the specific domain variability. It can automatically comply with the changing requirements of customer. In the paper,we give a description language to de- scribe the domain composition model. Then we give the mapping algorithm and mapping rule to convert the domain composition model together with the requirement of user into an executable Web services composition language. In the end,we give an example to demonstrate.
