摘　　要：在软件开发过程中,为了应对业务需求的多变性,通常需要耗费巨大代价不断对软件主体进行变动和更新。文章针对这种情况,提出了一种基于XML的动态插件机制。该机制使用XML对插件各项信息进行配置,包括动态类型、应用程序配置信息、数据库连接信息等,并在运行时根据实际业务需求动态加载所需插件,从而解决了因需求变化造成软件主体不断变化的问题,同时增强了软件的可扩展性。During the software development process, frequent changes of business requirements result in large costs for changing and updating software components. To solve this issue, this paper proposes an XML-based dynamic plug-in mechanism, which sets plug-in configuration information including dynamic type, application configuration information and database connection information through an XML file, and dynamically loads needed plug-ins according to the real business requirements at run time. The proposed mechanism enhances software scalability.
