摘要： 鉴于现有的AOP技术并不能适应工作流系统的需要，该文应用AOP的基本概念和方法，提出了一种可动态重构的工作流引擎架构，解决了工作流引擎基本结构的动态扩展以及工作流定义的动态修改问题。在应用此架构开发的一个符合WFMC标准的工作流引擎上，验证了此架构的可行性及动态重构的便利性，分析了架构的优缺点。

Abstract: The existing AOP technology is incapable to meet workflow engine’s requirements. Based on basic concept and methodology of AOP, this paper states dynamic refactoring workflow engine architecture. This architecture intends to resolve the dynamic extending of basic engine structure and modification of workflow definition at runtime. It verifies the feasibility and convenience on a WFMC compliance workflow engine developed using this architecture. It provides the advantages and disadvantages of this architecture.
