摘　　要：面向方面编程是一种基于关注点分离的新技术,它成功解决了面向对象编程中所存在的代码缠结和散射问题,但在软件设计阶段并没有得到很好的支持。通过分析面向方面编程的特点及其概念,比较UML2.0的两种不同扩展方法,提出了基于Profile机制来定义新的模型元素,并为其增加新的语义,再通过对象约束语言(OCL)来对这些新增模型元素加以约束,从而实现了UML2.0对面向方面建模的支持。Aspect-Oriented Programming which succeeds in solving the code tangling and scattering deficiency with Object Oriented Programming, but the Aspect-Oriented concepts have not been well supported at the phase of software design. By analyzing the characteristics of the AOP and the concepts, comparing the differences between UML2.0 extending methods, the Profiles Mechanism is taken to add new concepts about aspects, and then constraints expressed by OCL are added to the model elements. Finally, Aspect Oriented Modeling is supported by UML2. 0.
