Research And Design Of Message Middleware Oriented To Electronic Commerce System

With the increasing complexity of e-commerce business,the e-commerce system has gradually exposed defects such as high coupling,slow response speed and poor pressure resistance.Messaging middleware can effectively solve the above problems by virtue of its loose coupling,asynchronous speed-up and data buffering capabilities,but there are still a lot of design problems that need to be solved urgently in the research of message middleware for e-commerce systems.Based on the above considerations,this paper deeply researches and designs the message middleware for e-commerce system.Firstly,analyzes the development status of message-oriented middleware at home and abroad,summarizes the characteristics of mainstream message-oriented middleware products and the weakness of e-commerce system,summarizes the related technologies of message-oriented middleware,and puts forward the research contents and key problems in the design process of message-oriented middleware for e-commerce system.Secondly,aiming at the requirement of message-oriented middleware for e-commerce system,this paper constructs the hierarchy model of dissolving middleware for e-commerce system,designs the client layer,message communication layer,server layer and control layer,constructs the interaction process among each layer,and gives the design idea and method of key functions of each layer.Among them,in order to ensure the reliability of the message,a message compensation mechanism and a cache deduplication strategy are proposed;in order to fully meet the functional requirements of the e-commerce business for message queues,three types of message queues are designed:normal,time-sensitive and delayed;in order to match the e-commerce business rich and detailed services,realize flexible routing of messages,and establish a coarse-grained message distribution mechanism based on message exchanges and a fine-grained message distribution mechanism based on labels.Thirdly,combined with the message middleware hierarchy model and design principle for e-commerce system,and based on the complete life cycle of messages,the user portrait function architecture for ticketing system is designed,and the specific steps,algorithms and related methods in the implementation process of each level are given.Finally,the realized message middleware oriented to e-commerce system is applied to "Shengle" e-commerce system,based on the message production and consumption process of the user’s order business scenario,the core functions of the message middleware are checked and tested,the feasibility and effectiveness of the model are illustrated.
