基于微服务的气象信息决策支撑系统重构与实践

Reconstruction and Practice of Meteorological Information Decision Support System Based on Microservice

气象信息决策支撑系统在气象防灾减灾过程中具有重要作用,但是单体架构的气象信息决策支撑系统无法满足科学决策和智能减灾的需求,在扩展性和复用性等方面存在不足。基于Spring Cloud的微服务架构具有低耦合、易扩展的特点,已经在各大中型企业得到广泛的应用。本文通过对微服务架构中关键技术进行研究,提出了3种气象信息决策支撑系统架构的重构策略。针对气象信息决策支撑系统局限性,结合微服务架构特点,设计基于微服务的气象信息决策支撑系统架构,分为核心层、业务逻辑层和表现层,重点对业务逻辑层进行了重构和实现,并把重构后的业务功能应用到了气象防灾减灾监控管理平台,提高了系统的可扩展性和可复用性。

The meteorological information decision support system plays an important role in the process of meteorological disaster prevention and reduction,but the monolithic architecture of a meteorological information decision support system is difficult to meet the needs of scientific decision-making and intelligent disaster reduction,and there are deficiencies in scalability and reusability.The microservice architecture based on Spring Cloud has the characteristics of low coupling and easy expansion,and has been widely used in large and medium-sized enterprises.In this paper,through the research on the key technologies of microservice architecture,three reconstruction strategies of meteorological information decision support system architecture are proposed.In view of the limitations of meteorological information decision support systems,combined with the characteristics of microservice architecture,the framework of meteorological information decision support systems based on microservice is designed,which is divided into the core layer,business logic layer and presentation layer.The business logic layer is mainly reconstructed and realized,and the reconstructed business functions are applied to the meteorological disaster prevention and mitigation monitoring management platform,which improves the scalability and reusability.
