基于Web Services和EJB的校园一卡通系统接口的设计与实现

Design and realization of campus one-card-pass system interface based on Web Services and EJB

通过Web Services和EJB技术为校园一卡通系统的前台应用访问后端服务器提供统一的业务处理接口,从而使服务器同各种不同应用的业务逻辑相分离,前后端应用耦合程度降低,整体设计层次更为清晰;当校园规模扩大或学校应用业务增加时,只随需要增加新子系统,不需再对原有平台进行重建.

Web Services and EJB can offer a unified interface for the front application of one- card- pass system to visit back server, thus make server seperate from business logic of all kinds of application, lower coupling extent of front and back application, make whole design arrangement more clear. When campus scale expands or application bussiness increases,only need add new subsystem according to requirement, needn＇t rebuild original platform.
