AOP在HPMIS中的应用

Applying AOP to HPMIS

结合医院人员管理信息系统(HPMIS)中权限管理的开发过程,分析采用OOP(object oriented programming)技术处理横切关注点引发的问题和困难,研究在此情况下采用AOP(aspect oriented programming)技术来解决HPMIS中横切关注点模块化问题的解决方案。通过AspectJ,给出了AOP技术在HPMIS权限控制开发中具体的应用示例,实现了非主要功能的集中模块化,并在此基础上讨论了AOP技术的优越性。

This paper is based on the developing of access control management in a hospital personnel management information system.After analyzing the drawbacks of the conventional OOP means in solving the problems of crosscutting concern,the paper introduces the solution using AOP technology at the same situation.In the end the paper presents an implementation of AOP technology for solving access control in HPMIS using AspectJ,and achieves modularization of non-main functions.Finally the advantages of AOP technology are illustrated.
