摘要： 微服务架构和云平台容器化部署是当前软件工程实践中一个比较热门的话题,很多研究报告表明越来越多的软件开发者正在将单体架构向微服务架构转型。在将单体架构应用拆分成微服务架构应用的过程中,实施者面临着一个重要的挑战,即缺乏一个明确的方法将单体应用高效准确的进行拆分。针对这个问题,提出了一种基于数据库表的微服务拆分方法并实现了一个拆分工具。该方法通过收集项目中的所有 SQL 语句,并结合数据库表之间的主外键关系,生成表关联矩阵,根据这个表关联矩阵初步划分出一部分微服务。然后根据测试案例收集所有的交易链路,再结合交易链路分析表和微服务之间的关系,计算出独立的表和微服务的关联度矩阵,根据这个独立的表和微服务的关联度矩阵来完成最终的微服务数据库表的划分,最后按照提出的规则进行微服务代码的拆分。实验结果表明,所提方法可以帮助软件开发者高效准确地进行微服务拆分。
