摘　　要：运行时行为模型构造是面向可靠性预计的软件运行时模型构造的组成部分,为软件可靠性预计提供运行时组件与组件之间的动态交互关系和状态之间的转移概率信息。基于Java开发平台提出了一种基于非侵入式监控的软件运行时行为模型的构造方法,包括获得当前时刻的运行时体系结构模型;根据运行时体系结构模型确定监控对象;声明监控方法中的代理Bean;声明监控方法中的监控Bean,实现对组件动态调用信息的提取;声明代理Bean和监控Bean的接口;基于模型构造算法实现对运行时行为模型的构造等步骤。基于Rainbow-znn软件进行了实例应用,验证了所提方法的可行性。Runtime behavior model construction is a component of software runtime model construction oriented to reliability prediction.It provides runtime component-to-component dynamic interaction relationship and state transition probability information for software reliability prediction.Based on Java development platform,a construction method of software runtime behavior model based on non-intrusive monitoring is proposed,including the following steps:obtaining the current runtime architecture model;determining the monitoring objects according to the runtime architecture model;declaring the proxy Bean in the monitoring method;declaring the monitoring Bean to realize the extraction of the dynamic component interaction information;declaring the interface between the proxy Bean and the monitoring Bean;based on the construction algorithm,the runtime behavior model is constructed.Finally,based on the Rainbow-znn software,an example is carried out,which verified the feasibility of this method.
