Structural conflict is one of the key issues in the development of the aspect-oriented software. We propose a framework based on the conceptual model and the reflection mechanism to solve the structural conflict. It achieves decoupling between the base program and definition of the pointcut by adding a conceptual level between them. In the process of implementing the framework, we consider the meta level in reflection mechanism as the conceptual level, and the meta objects are generated by the logical information in base program automatically. The framework has solved the structural conflict in AOP application at the semantic level.
