摘要
根据卫星遥感在灾害监测与救灾减灾中的应用特点,研究了减灾应用中卫星数据申请、生产的规范和流程,并根据规范和流程,利用SSH和DWR框架实现了一个减灾卫星运行管理系统。在该系统中,利用SSH框架实现了MVC软件设计模式中M模型层、V表示层、C控制层的分离,降低了系统的耦合度,并利用Spring的面向切面编程(AOP)特性,实现了系统中的数据库事务和日志模块,降低了系统的开发难度。运行结果表明,该系统采用DWR框架实现了AJAX,减少了页面的刷新次数,改善了显示效果,提高了用户的体验度。
Based on satellite remote sensing for disaster monitoring and disaster mitigation,studied the process of application of satellite data and production specifications for disaster reduction.According to the process and specifications,the operation management system for mitigation satellite based SSH and the DWR is designed and implemented.The application of the SSH framework and AOP（aspect oriented programming） not only simplified the development of the system,but also improved the expansibility and maintainability of the system.In addition,the use of DWR prompted the efficiency of web pages visited,and improved the user experience.
