摘要
针对灌区信息化过程中因投资的阶段性而导致的软件系统分割和异构给集成带来的困难,研究了基于门户的异构软件系统的集成模型、结构和实现方法。这个方法充分利用Java所固有的平台无关性,通过Web服务来实现基于门户的集成。门户采用网站方式,通过模型视图控制（Model View Control,MVC）模式访问外网的订阅数据库,实现对各种页面的浏览。业务系统通过Web服务建立与异构子系统的交互,实现访问控制和数据交换。而单点登录则实现了对用户权限的一次性认证,因此,简化了操作,也保证了系统执行过程管理的统一性。
In order to solve problems of software system partition caused by investment phase variety and troubles for integration caused by heterogeneity in the information explosion process for irrigation area,research was made on integration model,structure and implementation approaches of portal-based heterogeneous software system.Taking full advantage of Java＇s platform independence,portal-based integration is realized through Web service.The portal website applies model-view-control（MVC） paradigm to access external subscription database to browse all pages.The operation system makes access control and data exchange by establishing interactive relation with heterogenous subsystem through Web service.Single sign-on system makes disposable authentication for user privilege,thus the operation is simplified and the administration uniformity of system implementation is also ensured.
