基于J2EE的校园移动GIS的设计与实现

随着各大高校信息化建设的深入开展,校园网络的规模逐渐扩大,移动应用已逐渐占领校园市场。本文通过问卷的方式了解了大学生的日常学习和生活需求,开发出基于J2EE与Arc GIS平台的校园移动GIS——＂长大校园通＂,解决了长大师生获取校园资讯不便、出行困难等难题。系统整体采用J2EE体系架构保证其具有良好的安全性、可用性与可移植性。在基本信息服务实现中采用部分静态地图数据客户端存储、服务端请求数据利用SQLite在本地缓存等方法,实现信息离线缓存浏览,减少网络访问流量,提升用户体验;采用网络信息抓取技术从校园网上获取动态信息,避免信息内容管理系统的重复建设。

Design and Implementation of Campus Mobile Geographic Information System Based on J2 EE

With the further development of colleges and universities＇ information construction and the spread out of the campus network scale,the mobile application has gradually occupied the campus market. In this paper,getting the daily needs of college students studying and living through the questionnaire survey,a campus mobile geographic information system,called ＂Yangtze Campus＂,has been developed based on J2 EE and Arc GIS platform. By using it,teachers and students can access to campus news,get travel and other information easily. J2 EE architecture is adopted to ensure the system with good security,usability,and portability. In the process of basic information service implementation,we use Geodatabase to store map data and SQLite to store temporary data requested from the servicer in the client end,which has realized offline cache browsing,reduced network traffic,and provided a good user experience. And,the network information captures technology is used to get dynamic information from the campus website,which avoids repetition construction of the information management system with same contents.
