摘　　要：随着国家电网深入数字化改革,移动化作业场景越来越迫切,服务入流量指数级倍增,传统单体系统架构已不能满足现有多用户高并发移动作业需求,而微服务集群架构下虽系统可用,但数据一致性和可靠性却得不到保证,这严重影响核心业务正常流转,又会引发许多数据治理问题。针对这类问题,本文提出基于中间件方案来解决高并发场景下分布式系统服务幂等性问题,通过对服务实例进行幂等性处理,提高系统的可靠性与准确性。实验表明,相比于不使用中间件或使用其它中间件,该方案有效提高了应用服务的数据准确率,保证了应用及系统有效平稳运行。As state grid digital reform in depth,mobile operation scene has become more and more urgent,service into the traffic exponentially multiply,traditional monomer system architecture can not meet the existing multi-user concurrent mobile operation needs,and although the micro service cluster architecture system is available,the data consistency and reliability are not guaranteed,which serious influence normal core business flow,this raises many data governance issues.Aiming at this kind of problem,this paper proposes a middleware scheme to solve the service idempotency problem of distributed system in high concurrency scenario,and improve the reliability and accuracy of the system by idempotency processing of service instances.Experimental results show that compared with using no middleware or other middleware,this scheme can effectively improve the data accuracy of application services in mobile operation scenarios,and ensure the effective and smooth operation of applications and systems.
