Design And Implementation Of Car Loan Management System Based On RESTful

In recent years,the rise of the Internet spawned a number of new industrial model.For example,with credit,the Internet online financial model has a greater popular than the traditional bank loans.As a subdivision of the Internet banking,automotive finance is able to satisfy the desire of many young car buyers,welcome to the majority of white-collar workers.At the same time,as a short invenment cycle,high interest rates,low amount,information transparency and security is relatively high financial products is favored by many investors.As a result,more and more startups will reach out to this field.It is a car loan management system to introduced YQD system in paper,used to achieve network lending function.It introduced the characteristics and present situation of auto loans and analyzed the development model of domestic and foreign car loans,and developed a management system for the main car loan business in the article.It is based on the RESTful architecture,with Spring,Spring MVC and Mybatis integrated SSM development framework to build a system development platform,using of caching technology and Shiro security authentication technology to ensure the performance and security of the system.Firstly,It confired the user of this system by business stated,including the salesman,the store owner and the backstage administrator.On this basis,It determined the four functional modules of the system with the demand analysis of the system,including front-bank module,loan application module,the store module and backstage management module,where in the front module,the salesman version of the loan application module and the risk control management and financial management of the backstage management is the core of this system.Then,It is designed that the system overall architecture,according to the characteristics of the Internet system,using the hierarchical design model to construct the concrete realization of this system.At the same time,the overall function of the system was decomposed by functional decomposition diagrams,showing each subsystem has the specific function,and giving a detailed functional design for each module.Then,by comparing their respective characteristics of the three major domestic database,has chosed Mysql that open source database as the data storage at the end.the table structure and the table field of the YQD system is carried out detailed design.This paper mainly introduces the realization of the pre module,the salesman loan module and the risk control management and financial management of the backstage management system.It is describes with the class diagram and the sequence diagram that the implementation steps and the data interaction of process of the core funcation in this system.Finally,the developed system is deployed to the Web test platform,with the functional modules tested,the test results analyzed,and the work of this paper summarized and prospected.After the completion of the test system,it is deployed to the company’s Web server.The package of APP was taken to the user on trial.After preliminary checkout,the feedback of user is good,and the system can satify the basic business needs.Then,after the trial of the company’s internal staff,the background management system also to meet the user requirements,and can achieve the basic functions of the loan management.Following the expansion of the business,the system also consider to improve the performance of the system,including stability,response time and other aspect performance.
