Design and Implementation of Mobile Learning Platform System Based on JavaEE and Android

为解决移动学习平台系统视频资源数据展示能力弱、师生互动交流较为困难以及移动学习效率低下等问题,设计和实现了基于JavaEE和Android的移动学习平台系统.该系统服务器端采用JavaEE最新整合框架SpringMVC4+Spring4+Mybatis3(SSM),使得展示层、控制层、业务层以及数据持久层四层分离,降低了各层之间的耦合度,提高了系统的可维护性与可扩展性.移动客户端采用自定义树形扩展算法实现N级视频课程资源目录结构,提升了系统资源展示的灵活性;采用蓝牙技术实现多人聊天,增强了师生互动性;缓存采用LruCache中的LRU算法避免图片出现内存泄漏问题.实践应用表明,该系统可以显著提高移动学习者的学习效率.

In order to solve the problems of weak display ability of video resource data,difficulty of interaction and communication between teachers and students,and low efficiency of mobile learning in mobile learning platform system,this research designs and implements the mobile learning platform system based on JavaEE and Android.One of the latest integrated framework is SpringMVC4+Spring4+Mybatis3(SSM)of the JavaEE that is used on the server side of the system,which separates the display layer,control layer,business layer and data persistence layer,reduces the coupling degree between the layers,and improves the maintainability and expansibility of the system.The Mobile client uses self-defined tree expansion algorithm to realize N-level video curriculum resource’s directory structure,which improves the flexibility of system resource display.This system also applies in Bluetooth technology to realize multi-person chat,which enhances the interaction between teachers and students.The LRU algorithm in LruCache is used to avoid the OOM problems.The practical application results show that the system can improve the learning efficiency of mobile learners significantly.
