The Design And Implementation Of Inter-bank Funds Clearing System Based On Microservice Architecture

The Safe and efficient inter-bank fund transfer plays a key role in promoting national economic development and improving social fund transfer efficiency.With Internet financial industry's the rapid development and strict financial supervision policies increasingly,the traditional bank fund processing system based on the centralized system architecture design and development,has been unable to satisfy the requirements of rapid and efficient fund clearing between banks.Therefore,the thesis based on micro-service designs a distributed fund processing system to solve the traditional inter-bank centralized fund clearing systems exist problems.This thesis described the structure of the clearing system,and analyzes some key processing services in the system in detail.The main research work of the thesis includes:Firstly,this thesis introduced the research background and significance of inter-bank fund clearing system,analyzed the research progress of information system architecture technology,and summarized the key technologies of distributed system development,such as micro-service communication,micro-service invocation and service subscription publishing.Secondly,according to the inter-bank fund clearing system processing status,inter-bank business development trend,system functions and non-functional requirements,this thesis proposes a design scheme to build an inter-bank fund clearing system,this scheme based on the X86 server operating environment,adopted micro-service system design principles,used cloud computing,virtual machine container image deployment techniques and so on.The system based on Maven and SpringBoot engineering technology developed and implementation,used HTTPS protocol to transmit messages between system and banks,used Dubbo protocol to implement system internal services remote calls,used Nacos to implement service registration and configuration management between services,and used Jenkins to complete service mirror product release and deployment.Finally,used black-box testing method to complete functional testing of the micro-services,and verified the processing performance in the single instance and multi-instance scenarios of the micro-service.This inter-bank fund clearing system with microservice architecture design and development has been successfully putting into a certain city operation.The system is running stably,and can quickly realize bank's the diversified business needs and fund clearing requirements,and achieve the expected goals for the financial industry.It has guiding significance to the design and development of similar systems in the financial industry.
