基于反射机制的ERP构件组装系统
|
摘要
软件行业的工业化趋势导致了构件的产生。能够像硬件系统那样,将部分软件组合起来构建软件系统,一直是软件行业多年来追求的目标。构件技术的出现,极大地满足了多个应用领域的要求,使得各种技术形成的构件可以最大程度地重用。这就引出了大规模软件开发所面临的另一个问题:如何建造构件库,并有效地组织和管理。目前,国内外在构件库方面已经有了一定的研究成果,但是仍存在一些需要改进之外,例如,通用性、性能以及更科学地管理等方面已经不能满足现在应用系统越来越高的要求。
本文在研究了现有构件库理论的基础之上,结合了现代ERP系统对软件库的特殊要求,对现有的构件库的理论和技术进行了一系列的改进,提出了一套更加通用、灵活、性能更好的构件库系统实现技术与方法
在构件组装方面,本文扩充了一种基于消息总线和反射机制的构件交互模式。这种模式可以支持构件之间发布/预订和点对点两种交互。基于这种模式,可以改进现有的构件库在构件反馈信息中缺少构件运行时情况记录的不足,可以更好地为构件库用户提供准确,真实的构件反馈信息。
本文主要分为三大部分。第一部分阐述构件的相关概念、模型及描述语言等。第二部分介绍ERP构件及构件库,首先介绍ERP构件模型,然后主要介绍构件库的管理,如构件入库、构件检索、构件删除等。第三部分阐述构件的组装机制,首先介绍基于反射机制的构件组装方法,在此基础上用一个实例模型详细介绍了构件的组装过程。
本文研究的目的和意义在于将反射机制的概念引入到构件组装方法中,体现了主动服务的思想,提高软件复用度,缩短应用系统的构建周期。最后,本文在此基础上开发了一个实例模型来证实基于反射机制的构件组装方法是可行的,进一步为主动服务技术的研究提供支持。
Software industrializing brings out the concept of component, which combines some software to work together as a whole system, just as the hardware system. The component technology can meet the requirements of different fields, However, another problem is raised, how to establish the component library system and offer effectively organeze and manage of components? At present, although some progress in the component library system is attended, some aspects still need to be improved. For example, it still can not meet the requirements in terms of generalization, capability, security and scientifically management.
Basing on the original theory, combing the modern ERP system and its special requirement, the thesis introduces some improvement on the theory and technology of component library and a more general reliable technology and method to implement it.
In terms of component assembly, thesis extends collaboration model betreen components based on message bus and reflection. The model supports two communication mode, publish/subscribe and point to point. Based on the model, ERP component library system can improve the original component library system to meet the shortage of lacking operation record in information feedback, so as to better offer precise and real component feedback information for the component library system users.
This article is divided into three main parts. The first part of introduces the relevant concept、model and language of components. The second part introduces EPR components and component-library , it starts to introduce the EPR component-model, and then it mainly introduces the management of component-library, such as how to put components into library, and how to query components or delete components and so on. The third part introduce the assembling methods of components. It starts to introduce the method to assemble components based on reflection, and then introduce the process to assemble components with a instance model.
The purpose and significance of this article is to put the concept of reflection into the assembling methods of components. It takes advantage of the idea of active service to increase the reusement of software and shorten the period to develop a system. Finally, this article uses a instance model to confirm that it is right to use the method based on reflection to assemble components. Besides,it provides the support of further study of active service.
