基于插件技术的企业应用集成架构研究

Architecture research of enterprise application integration based on plugin

企业应用集成已经成为实现企业主要战略目标的必需手段和捷径。胜利油田物探研究院在实施企业信息化规划过程中遇到许多实际问题,不同时期实施的企业应用形成一个个信息孤岛,为企业应用集成带来诸多不便。插件式体系结构的灵活性给企业应用集成提供了一种实现途径。插件技术将应用程序分为主程序和插件程序2个部分,两者之间通过接口实现交互,使系统具有较高的可伸缩性。插件机制实现的技术手段之一是OSGi,OSGi规范的核心框架提供了一个通用、安全、可管理的支持以Bundle方式下载并扩展部署的.1ava框架。基于OSGi规范和框架的实现的插件式企业应用集成框架,具有灵活性、松耦合、跨平台、扩展性好等特点,能够很好的适应企业应用集成的需要。

Enterprise Application Integration（EAI） has become the main strategic goal to achieve the necessary business tools and shortcuts.In the implementation of enterprise information planning,Geophysical Research Institute of Shengli Oilfield found a number of practical problems encountered.The implementation of enterprise applications at different times to form one information silos,enterprise application integration for the inconvenience.The flexibility of plug-in architecture to the enterprise application integration provides a means of realization.Plug-in technology applications and plug-ins are divided into two main parts,interact through the interface between the two,the system has high scalability.Plug-in mechanism for the technical means to achieve one of OSGi,OSGi core framework specification provides a common,secure,manageable way to support Bundle download and expand the deployment of the Java framework.Framework based on the OSGi specification and implementation of enterprise application integration framework plug-in,flexible,loosely coupled,cross-platform,and good scalability,and can well adapt to the needs of enterprise application integration.
