Web Services在企业信息系统集成中应用架构的研究*

为解决目前大中型企业内异构环境下的信息系统集成,并实现与企业外部信息系统的通信,以SOA的观点出发,提出一种完全基于OSS(开源软件)平台、轻量级的系统集成应用架构.该架构不使用EJB来实现企业总线而使用轻量级ESB:Mule作为集成服务的基础;使用Axis作为Web Service的实现;充分使用可配置的策略实现各类系统组件的灵活拆装.系统外部仅开放SOAP/Web Services接口提供外部系统服务通信.这种架构具有SOA特性及相当好的集成效果.最后实现了一个DRP(Distribution Resource Plan,企业分销资源计划)系统原型;系统与企业原来的ERP灵活通信.

Research on Enterprise Information System Integration Architecture Using Web Services

In order to implement the system integration of large and medium-sized enterprises under the heterogeneous environments and implement the communication with information system outside the enterprises,this paper advanced the lightweight and agile system integration apply architecture from the view of SOA,which is absolutely based on the platform of OSS.In stead of using EJB,this architecture used the most best practice mode of open source based-lightweight ESB like Mule as the basis of integration service,used Axis as the Web service engine and used configurable tactic to implement a heterogeneous system integration.This architecture has good integration effect as the character of SOA,which uses SOAP/Web Service to provide the service communication for exterior system.At the end of the thesis,it implemented a system archetype of DRP(Distribution Resource Plan of Enterprise),and so that the system could communicate with enterprise's primary ERP neatly.
