【摘 要】
伴随着全球经济一体化发展，全世界各个国家经济之间逐步开始构成一个彼此互相开放，互相联系、互相依赖的有机体。而随着我国改革开放和加入世界贸易组织，中国已经成为了世界经济网络中不可或缺的一个重要组成部分。时至今日，全世界的外汇电子交易平台的功能整合以及前后端集成趋势已经以雨后春笋的势头快速发展，并且正在朝云计算、大数据应用方面进展。然而中国的外汇行业电子交易系统明显落后于国外，目前仍处于起步阶段，并且与国际行业水平至少相差5年时间。因此，开发一款外汇业务管理系统，用于进一步提升电子化、网络化的交易功能，形成外争的外汇供应链金融，是十分重要与可行的。
本外汇业务管理系统采用微服务架构设计，并按照业务功能进行垂直拆分成4个微服务。各个微服务部署在独立的服务器中，并通过轻量级的通信机制（基于HTTP的Restful API），进行相互协调、互相配合，从而为用户提供最终价值。在安全上，采用JWT（JSON Web Token）集成Spring Security安全框架来搭建单点登录平台，从而进行用户认证和权限鉴定。在MVC架构设计上采用SSH（Spring、 Spring MVC、Hibernate）技术框架进行模型(model)-视图(view)-控制器(controller)的开发。在实时日志收集分析系统上，采用ELK（ElasticSearch、Logstash、Kibana）技术架构搭建。

【Abstract】
With the development of global economic integration, the economies of the world have gradually begun to form an organism that is open to each other, interconnected and interdependent. And with China's reform and opening up and accession to the world trade organization, China has become an indispensable part of the world economic network. At present, the function integration and front-end integration trend of the global electronic foreign exchange trading platform have mushroomed rapidly, and are making progress in cloud computing and big data application. However, the electronic trading system of China's foreign exchange industry obviously lags behind that of foreign countries. It is still in its infancy and at least five years behind the international level. Therefore, it is very important and feasible to develop a foreign exchange business management system for further improving electronic and networked trading functions and forming foreign exchange supply chain finance with external disputes.
This foreign exchange business management system adopts micro-service architecture design and is vertically divided into four micro-services according to business functions. Individual micro services are deployed in separate servers and coordinate with each other through a lightweight communication mechanism (http-based Restful API) to provide the ultimate value to users. In terms of Security, JWT (JSON Web Token) is used to integrate Spring Security framework to build a single sign-on platform for user authentication and authorization authentication. In MVC architecture design, SSH (Spring, Spring MVC, Hibernate) technical framework is adopted to develop model-view-controller. In real-time log collection and analysis system, ELK (ElasticSearch, Logstash, Kibana) technical architecture is adopted to set up.
