Design And Implementation Of Online Mall System Based On Micro Service

As the consumption level improves and science and technology develops,there is a growing need for online shopping and function system.The surge of users has also brought great challenges to the load capacity of the system.In the architecture,all the functions in a single application are achieved in one system,while now cannot satisfy the demand,and the server will easily collapse under the action of such a large traffic volume.Therefore,various problems derived from the demand iteration of the e-commerce project with the monomer architecture should be solved.This topic is to solve various problems arising from the monomer structure e-commerce project with the demand iteration.Therefore,the architecture of micro-service is used to design,to ensure full decoupling between businesses,independent operation between services,and to realize the mall system with high scalability,high availability and high concurrency.The single architecture of system functions exists in the form of micro-services(including shopping cart management service,central authentication service,etc.).Service governance is carried out among services through service registration,service fault tolerance,service remote invocation,service tracking,distributed transaction,etc.,to guarantee the operation and the service secure and steady.The service feature of the system are partitioned according to the usage of characters,and the system functions are corresponding to users one by one in the way of use case diagram.After the overall design of the system,several service modules are designed and described in detail by means of sequence diagram.In the concrete implementation,other distributed technologies such as message queue,cache,etc.,guarantee the concurrency ability of the system,improve the reaction speed and the available of the system.In the last stage of this paper,the author had finished comprehensive test on function and performance to guarantee that the system operates well and maintains excellent performance indicators.The test results verification the feasibility of the system.Currently,the design and development of the system and all the testing work have been completed and the system has been on-line.
