摘　　要：针对干部培训工作面临的教育资源不足,工学矛盾等问题,开发了网上学习系统。系统采用J2EE平台的MVC分层设计方法,使系统能适应未来不断变化的需求和扩展;采用系统建模方法,使系统各部分功能逻辑关系更清晰,开发测试更容易;采用视频学习进度控制、测试题触发控制等方法,完善了学习管理机制,有效提高了系统互动教学的效果。系统实现了在线学习、后台管理、流媒体视频点播、系统权限管理等功能,满足了党校学员通过互联网自主学习的需求,同时,对党校提高办公效率,实现信息资源共享起着重要作用。The online learning system is developed for the shortage of cadre training educational resources and the big engineering contra- diction. This system is using MVC based on J2EE and can adapt to future variational requirement and extending. Using system modeling, systemic functions logical relation is more clear and development test is more easy. Using video learning progress control and test ques- tions trigger control ,the learning management mechanism will be more perfect, and the interaction teaching effect will be enhanced effec- tively. This system includes online learning ,back-stage management, stream media VOD, system privileges management etc. , and auto- nomic learnin~ requirements are satisfied, oartv school＇s office efficiencv is deve.loned, inforrnatinn re^ouree~ are. e^ninv^d tnof^thf^r
