面向方面编程在软件进化中的应用

The Application of Aspect-Oriented Programming in Software Evolution

软件进化是提高软件系统生命力,减缓其废退步伐的有效办法。分析了AOP(面向方面编程)的基本思想、软件进化的必要性及其现状,提出了采用AOP思想进行软件进化,以提高软件进化的有效性。文中给出了一个结合软件进化与AOP的实例。通过在EJB安全性方面初步应用AOP进行软件进化证明了两者结合的有效性。

Software evolution is a valid way that increases the software system＇ s vitality and slows down its deterioration process. This paper analyzes the thinking in AOP （Aspect - Oriented Programming）, the necessity of software evolution, its current situation, and introduces a method of applying AOP into software evolution. AOP is applied in the EJB security service to realize software evolution, and the efficiency of this combination is proved.
