摘　　要：软件企业实践将遗留软件系统解耦成基于微服务架构的系统,以提高软件的可维护性,达到较快市场交付.评估微服务开发阶段的代码可维护性是一个关键问题,其面临数据多源化、可维护性关注点多样化的难点.通过分析源代码、代码运行轨迹、代码修订历史,提出一种多源特征空间模型以统一表示软件多源数据,并基于该模型,从功能性、模块性、可修改性、交互复杂性等关注点度量微服务代码可维护性.据此实现了原型工具MicroEvaluator,并在开源软件上进行了实验验证.Software industrial practices decouple legacy software systems into microservice architectures to improve software maintainability and to achieve faster market delivery.Evaluating microservice code maintainability during the development is a critical issue,facing the difficulties of multi-sourced data and diverse concerns of maintainability.By analyzing source code,code execution trace,and code revision history,a multi-sourced feature space model is proposed to unify the representation of software multi-sourced data.Based on this model,a microservice maintainability measurement system is established with comprehensive metrics,in terms of the concerns of functionality,modularity,modifiability,and interaction complexity.Accordingly,a tool prototype called MicroEvaluator is also implemented,and experimental analysis is carried out on open-source software systems.
