摘　　要：针对在应用系统中引入工作流技术进行集成的问题,提出应用控制反转模式对嵌入式工作流系统进行集成的方案,以降低集成耦合度、减少系统复杂性、提高组件重用率。避免不适当的集成方法导致应用系统代码的侵入、结构的破坏以及系统紧耦合所造成的系统灵活性和可扩性差、维护难度大的问题。给出开源工作流系统OSWorkflow和基于Java EE轻量级架构的应用系统的集成实例和实现过程。The application of Inversion of Control（IoC） pattern is introduced to resolve the problem of integration while introducing embedded workflow technology into the application system, so that the coupling of integration and system complexity can be reduced, and the rate of component reuse can also be improved effectively. The problems such as the invasion of system codes, the damage of structure, less flexibility and expansionary led by the tightly coupled system and difficult maintenance can be avoided which result from an inappropriate integration method in the application system. An integration example of Open Source Workflow（OSWorkflow） system and the application system based on Java EE lightweight architecture are given.
