基于SCA和ESB的企业应用集成系统研究与实现
摘要
随着Internet的迅猛发展,企业业务范围不断扩大,企业应用系统也变得越来越复杂。各子系统之间数据冗余,资源无法共享等诸多弊端导致系统的业务敏捷性差。因此,如何设计一个松耦合、敏捷的企业应用集成系统,使其能快速应对业务决策的改变,成为软件工程领域重点研究的问题。
SCA作为面向服务架构的编程模型,具有业务组件和传输协议、接口和实现相分离的特性,能够很好地解决系统模块间紧密耦合的问题。企业服务总线ESB能有效的实现服务组件的位置与传输协议的透明性,方便企业系统之间进行交互,易于对企业业务进行扩展。
本文在深入分析了传统企业应用集成方案的基础之上,针对其不足之处,结合SCA和ESB技术,提出了一种新的构建企业应用集成的架构模型SE-EAI。该架构模型利用SCA来指导各个服务组件的开发,实现最基本的IT基础功能。通过ESB对各服务组件的代理,能实现消息格式转化,动态路由和传输协议转化,方便不同系统之间的业务调用。从而实现服务的灵活调用和业务功能的无缝整合,这样既能充分利用企业已有资源,又能方便企业新业务的快速加入。
最后,本文将模型SE-EAI应用到企业信息管理系统中,验证了其可行性和有效性。
With the rapid development of Internet, the enterprise business range is expanding and their application system is becoming increasingly complex. However, there is a large of redundancy information in each department,information resources can not be shared, and these drawbacks cause poor system business agility. Therefore, to design a loosely coupled and flexible enterprise application integration system which be able to rapidly response to changes in business decisions is becoming an important issue in software engineering field.
As a service-oriented architecture,SCA can make business components and transfer protocol, interfaces and implementation separation, it can perfectly solve the problem that there exists tightly coupled among modules. ESB can make service component location and transfer protocol transparency effectively,make it convenient while the enterprises interact with each other, and make it easy when the business is expanded.
On the basis of analysis of the traditional enterprise integration solutions, a new framework for building enterprise application integration model SE-EAI is proposed to overcome traditional enterprise integration solutions shortcomings and combine with SCA and ESB technology. The architecture model uses the SCA technology to guide the development of the various service components, achieve the most basic IT infrastructure functions. Through service agency in ESB, message format conversion can be achieved, dynamic routing also can be formated. Conversion is facilitated in business calls between different systems. Dynamic location and seamless integration of services can be realized, and both full use of companies legacy resources and adding new business resources are achieved.
Finally, the model SE-EAI is applied to an enterprise management information system to verify its feasibility and effectiveness.
