【摘要】 单体式架构应用在湖南省应急预警信息精准靶向发布系统开发中已经难以满足现实需求，通过分析微服务架构在复杂系统中相对于传统单体式架构的应用优势，设计出一种基于微服务架构的应急预警信息精准靶向发布系统，系统选用Spring Cloud微服务框架，并对其进行适当的扩展，创建了基于该系统设计的注册中心与网关。系统采用GIS地图作为展示，并在GIS地图上提供精准靶向预估与发布功能，通过接入运营商数据及接口，将运营商接口的数据模型进行数据融合和处理，转换成系统需要的数据结构模型，辅助进行预警信息生成发布。所设计方案在湖南省应急预警信息精准靶向发布系统中得以实际应用，验证了该类系统使用微服务架构的合理性和有效性。更多还原

【Abstract】 The application of single architecture in the development of Hunan Province’s emergency early warning information precise targeting release system is difficult to meet the practical needs. This paper analyzes the application advantages of micro-service architecture in complex systems compared with traditional single architecture, and designs an emergency early warning information precise targeting release system based on micro-service architecture.The system selects the Spring Cloud microservice framework and appropriately expands it, The registry and gateway designed based on the system are created. The system uses GIS map as the display, and provides accurate target prediction and release functions on the GIS map. By accessing the operator data and interfaces, the data model of the operator interface is fused and processed,and converted into the data structure model required by the system to assist in the generation and release of early warning information. The design scheme has been applied in Hunan Province’s emergency early warning information precise targeting release system, which verifies the rationality and effectiveness of this kind of system using micro-service architecture.更多还原
