Design And Implementation Of Backstage Management System Of Mobile Internet Car Trading System

In recent years,with the rapid spread of the Internet and smart phones and the significant increase of online shopping penetration,the traditional car trading industry has begun to gradually move closer to the Internet,but mostly at the stage of showing information on the Internet,such as car information,price information,dealer information and so on.It just help users to skim through and contrast,but users'participation is not high and more links still have to do offline,so it did not solve the problem of low efficiency in deed.Therefore,the project aims to build a mobile Internet car trading system connecting consumers to sale-brokers and dealers and it adds chat module,group module,group purchase module,while users can directly bargain with the sales online through online telephone of the APP,which greatly improves the efficiency of both users' buying car and 4S shops' and brokers' selling car.This paper mainly introduces the back end part of the project.This paper firstly analyzes the background and realization significance of the mobile internet car trading system project.Through the comparative analysis of domestic and foreign products,some distinguishing features of the system are found and the research and development direction of the system is established.Since the author is mainly responsible for the back end,this paper introduces the technology and ideas in the process of the design and implementation of the system,including SpringMVC,Spring and Hibernate framework.Then it describes the overall physical architecture and back end architecture of the system,and analyzes the functional and nonfunctional requirements of the system background respectively.On the basis of the requirements analysis,the modules of the system back end are designed and realized in detail.In the process of system development,the author is mainly responsible for 4S shop module,brokers module,4S shop article module,group module,activity module,authority module and account module,in addition,also participated in the system needs analysis,prototype design,testing and so on.Finally,the paper summarizes the testing process and the results of the system and shows some operation results.In the whole system,the author completed the development of 4S shop module,brokers module,4S shop article module,group module,activity module,authority module and account module and realized the goal of role diversity,clear responsibilities,effective management of the background management system.At present,the system is in the trial operation phase,the module which the author is responsible for and participate in is running well.It both meets the needs of users and achieves the desired goal.
