| 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. |

| Abstract: |
| 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. |
