摘　　要：对单体系统进行微服务划分能有效缓解单体架构中系统冗余、难以维护等问题,但是现有的微服务划分方法未能充分利用微服务架构的属性信息,导致服务划分结果的合理性不高。文中给出了一种基于微服务架构的服务划分方法。该方法通过系统服务与属性的关联信息来构建实体-属性关系图,然后结合微服务架构的特征信息与目标系统的需求信息制定服务划分规则,量化两类顶点之间的关联信息,生成实体-属性加权图,最后应用加权的GN算法自动地实现系统的微服务划分。实验结果表明,该方法在服务划分的时效性上有较大提升,并且生成的微服务划分方案在评估指标上的表现更好。The microservice decomposition of the monolithic system can effectively alleviate the problems of system redundancy and difficulty in maintenance of the monolithic architecture.However,the existing microservice decomposition methods fail to make full use of the attribute information of the microservice architecture,which leads to the low rationality of service decomposition results.This paper proposes a service decomposition method based on microservice architecture.The method constructs an entity-attribute relationship graph through the association information of system services and attributes.Then the service decomposition rules are formulated by combining the feature information of the microservice architecture with the demand information of the target system,the association information between the two types of vertices is quantified,and a weighted entity-attribute graph is generated.Finally,the weighted GN algorithm is applied to realize the microservice decomposition of the system automatically.The experimental results show that the method greatly improves the timeliness of service decomposition,and the gene-rated microservice decomposition scheme performs better in terms of various evaluation metrics.
