摘要
为了提高Web开发效率,开发人员常常复用已有系统框架或成熟项目中现有的代码,但因此也导致了Web应用中总存在大量的冗余代码,冗余代码不仅影响程序的可读性和运行效率同时还会隐藏软件缺陷。通过研究Web应用源代码逻辑和框架的特性,提出了Web应用系统中基于源代码分析的冗余代码检测方法。从应用程序入口开始,根据代码之间的逻辑调用关系构建Web应用调用树,进而得到有效页面集、有效类与方法节点集;然后根据冗余检测算法检测出Web应用系统中冗余页面、冗余处理类与处理方法。为了评估冗余检测方法的有效性,包括漏检率与误检率,对两个JavaWeb应用进行冗余检测并通过人工注入冗余实验验证检测的有效性。实验结果证明,提出的冗余代码检测方法可以达到较高的检测效率。
In order to improve the efficiency of Web development,developers often reuse previous code in existing system frameworks or mature projects,but it also leads to a large amount of redundant code in Web applications.Redundant code not only affects the readability and operational efficiency of the program,but also hides software defects.We propose a redundant code detection method based on source code analysis in Web application system by studying the characteristics of web application source code logic and framework.The method constructs the Web application call tree according to the logical call relationship between the codes starting from the application entry,and then obtains the effective page set,class and method node set.A redundancy detection algorithm is presented to detect the redundant pages,the redundant service classes and the processing methods.In order to evaluate the effectiveness of the redundant detection method,including the missed detection rate and the false detection rate,two JavaWeb applications are used as the experiment to verify the redundant code detection method proposed,and the results show that the redundant detection efficiency is high.
