基于JAVA反射机制的规则引擎设计与实现

Design and Implementation of Rule Engine Base on Java Reflection

根据专家系统的推理机制和JAVA语言的反射机制设计实现了一个规则引擎,该规则引擎利用XML文档存储规则RETE算法匹配规则.应用程序通过实例化类调用规则引擎,改变了传统企业中业务过程和企业信息紧密耦合的情况,降低了企业信息系统的维护成本.

In this paper,a rule engine is designed according to reasoning of expert system,and is implemented by JAVA reflection.In the rule engine,rules are stored by XML document and matched by RETE algorithms.The application program calls rule engine by instantiated classes,and it will change relation of tight coupling between business process and corporate information,cut down maintenance cost.
