基于REST面向资源的企业信息集成平台框架
摘要
随着信息技术和网络技术的进步,企业实施的IT支持系统不断增多,企业将越来越多的注意力集中在面向业务过程的问题上,企业应用集成便成了企业必须面对和加以解决的非常复杂的问题。为实现异构环境下企业信息系统业务过程整合的要求,克服传统基于SOAP协议的Web服务在服务寻址性,连通性和接口统一性等方面的不足,本文提出了一种基于REST面向资源的企业信息集成平台框架模型。
本文针对在由资源服务组成的环境下,如何制定合理的资源模型表征方法、资源服务描述方法及业务流程编排,最终使该模型成为可行及有效的服务框架展开分析和讨论。本文的工作主要包括:(1)针对企业资源信息和业务流程的特点,提出一种资源元模型的形式化表征方法,以满足适应工作流调度的要求。(2)针对资源建模领域中存在的各种语义关系进行分析和建模。通过标注资源属性语义以及资源间的语义关系,以此来建立资源的相关性,支持资源在过程层次上的知识重构和重用。(3)对资源服务的定义和组成进行了分析,给出了服务描述和发布的方法,提出了基本的服务请求匹配算法。(4)提出基于REST面向资源的企业信息集成平台框架模型。首先,分析了资源支持层、服务封装层和业务执行层中各个模块的作用。其次,对关键模块的架构和设计进行了详细描述,提供了框架数据模型和核心算法的详细设计方案。(5)最后,基于J2EE开发了相应的原型系统,通过一个典型的多角色协作参与的电子商务业务流程集成案例来展示平台框架的应用方法。
通过本文的研究,为基于REST面向资源的企业信息集成平台框架模型提供了理论证明、抽象设计和技术实现。同时,结合理论模型和原型系统设计验证表明,该框架模型提供了一种实现异构环境下企业信息系统业务过程整合的有效途径。
With the progress of the information and network technology, the amount of the enterprise IT support system has been increased as well as the scope gradually extended. The enterprise begins to focus more and more attention on the business process issues and must face and try to solve the problem of enterprise application integration no matter how complex it is. In order to integrate the business process of enterprise information systems in heterogeneous environment, to overcome the shortcomings of traditional SOAP-based web service, such as lacking of addressability, connectedness, and uniform interface, this thesis presents framework of REST-based resource-oriented enterprise information integration platform.
In this thesis, we research and analysis the problem in the resource based environment including how to formally representing the resource meta-model, how to describe the resource service and how to organized the service to represent the business process. The work mainly includes following aspects. 1. We propose a formal method to represent the resource meta-model according to the feature of enterprise resource and business process. 2. We analysis and model the semantic relationship between resource models aimed to establish the relevance of the resource to support the reconstruction and reuse of knowledge. 3. We analysis the definition and composition of the resource service and propose a method to describe the published RESTful service as well as a basic service request match algorithm. 4. We outline the model of REST-based resource-oriented enterprise information integration platform framework. Firstly we explain the responsibility of the resource support layer, service encapsulate layer and business execution layer. Then we provide the architecture, detail design and data model structure for the core components. 5. Finally, we build a prototype system based on J2EE and use a multi-role collaborative e-commerce business case to demonstrate the platform applies to business process level integration.
This thesis presents a novel way to integrate heterogeneous systems with RESTful web services, and a prototype of REST-based resource oriented enterprise information integration platform is implemented based on the framework presented which opens a new prospect to traditional enterprise applications integration.
