The Design And Implementation Of Middle API Using Spring

With the development of the society,the applications in mobile phones have become more and more widespread.Nowadays,many applications send requests to underlying services through interfaces in developments.However,it is much complex to process and store data for underlying servcices in businesses.The model that the applications interact directly with the underlying services leads to that the underlying codes contain a wide variety of business logics scattered in various different underlying services,which brings many difficulties for maintenance and expansionThis paper developed a middle API system base on the Spring framework in order to solve above problems.Our main aim is to isolate the direct interactions between applications and the underlying services so that the system can satisfy the requirement.The middle API is located between applications and the underlying services.The applications provide a user-friendly interface,and thus the underlying services can store and access data easily.This paper describes the requirement of the middle API system base on Spring framework.The API system serves as a middle layer,which monitors the requests of applications,send the requests to the underlying services,and processes data or then send the data to the applications.In this way,the middle API isolates the direct interaction between the applications and the underlying services,and improves maintainability and scalability.The paper uses use case diagrams,class diagrams,and sequence diagrams to discuss the design of the system.Also,it gives some core codes.Finally,the paper explains the concrete realization of logic with the caption,and verifies the effectiveness of the system with actual pages.
