摘　　要：面向服务的集成(SOI)已成为当今IT系统集成的一个时尚。在SOA环境下,业务被划分为一系列粗粒度的业务服务和业务流程,形成松耦合、可重用的功能构件。Web服务技术将功能构件通过服务之间定义好的接口联系起来,并使各个构件可以用统一和通用的方式交互。近年来,国内许多大学进行了合并和扩建,旧有信息系统已经无法满足业务的需求。如何集成旧有孤立的信息系统,构建开放的信息系统架构,是当前高校信息化建设中亟待解决的问题。本文设计并实现了一种基于P2P的高校信息系统SOI解决方案,结合P2P和SOA优势,对高校大量异构的"遗留系统"进行封装重用,大幅降低集成成本,高效进行整合,并解决了传统信息系统SOI出现的网络性能瓶颈问题。Nowadays, Service-Oriented Integration （SOI） has been a fashion in IT system integration. In the environment of SOA, business is divided into a series of business services and business procedures, which become the loose coupling and reusable function components. Web service makes function components link together through defined interfaces between services,and makes components interact with each other in uniform and universal mode. In recent years, many universities were merged and extend. The old information system cannot satisfy the business’s needs. How to integrating the old isolated information system and building an open framework of information system is a major problem of the current campus information construction. This paper designs and implements a SOI resolved schema for campus information system based on P2P. On integrating the advantages of P2P and SOA technologies, we encapsulate and reuse a great deal of heterogeneous ‘legacy system’ in campus, thus cut down a great part of the integration cost and enhance the integration efficiency. Furthermore, this method solves the network performance bottleneck which is to be emerged in traditional information system SOI.
