Research And Design Of Bulk Commodity Procurement And Transportation System

China is a major demand and import and export country for bulk commodities,and occupies an important position in international bulk commodity trade.Taking timber trade as an example,the trade delivery cycle is long,the single transaction amount is large,and it involves crossborder trade processes.The business process is complex and changeable,which brings great challenges to the trade management of related enterprises.The use of ERP system can reduce the burden of enterprises,improve the efficiency of enterprise management,and strengthen the competitiveness of enterprises,but the existing general ERP solutions are difficult to meet complex business needs,and need to be customized for the actual needs of enterprises.This research is based on the ERP system of a timber bulk commodity trading enterprise.The ERP system used by the enterprise adopts a single architecture design with fast development speed and low deployment difficulty,but it has disadvantages such as high coupling,poor scalability,and low flexibility,and it is difficult to meet the needs of enterprise development.In order to solve the above problems,this paper studies the design and implementation of ERP system based on micro-service architecture with procurement and transportation business as the starting point.The specific research work is as follows.(1)Design of procurement and transportation system based on microservices.Starting from the principles of microservice design,this paper designs the system architecture in terms of service discovery and configuration,double-layer gateway design,and inter-service calls,and designs the background database,uses Redis cache to improve data access efficiency,and ensures distribution through distributed transaction management.data consistency under the database,and finally use Docker to implement containerized deployment.(2)High availability solution design.This paper starts from the upstream,midstream,and downstream stages of microservice invocation to design a high-availability solution,using load balancing,service degradation,and service fuse strategies to ensure that upstream service requests are evenly distributed downwards,and that the service itself runs stably and in a timely manner.Handle downstream suspected faulty services,avoid service avalanches,and ensure the stable operation of the system.(3)System security design.Based on the RBAC model,a functional rights allocation strategy is designed for enterprise data security requirements.On this basis,user groups are added to simplify the rights allocation process,and a rights authentication center is designed to ensure that user login and business function use are subject to rights restrictions.The front-end message transmission encryption and password encryption storage methods are used to ensure the security of the login process and the user password information stored in the database.The system test shows that the system meets the demand plan,the functions are complete,and the system performance meets the daily use needs of the enterprise.The system is currently being put into use in the enterprise,and the system is running smoothly,which has played a positive role in enterprise management.In addition,the design method and idea of ERP system based on microservice architecture in this paper has certain practical value and has reference significance for similar enterprise system design.
