Design And Implementation Of P2P Lending System Based On Springbook Framework

With the popularity of the Internet and economic development,P2 P lending has become more and more popular.The emergence of P2 P lending system has completely changed the traditional way of lending.It makes the lending process become simpler and more convenient.The emergence of P2 P lending system has solved the urgent need of some enterprises with difficult capital turnover and avoided the risk of enterprise bankruptcy.Based on the market demand,combined with the existing P2 P lending system development model and related technologies.The P2 P lending system is designed in a modular way.The system supports online borrowing,repayment,financial management and other functions,and has good operability.In this thesis,B/S architecture is used to realize the design of P2 P network lending system.Technically,it realizes the communication mode between customers and back office administrators,and establishes a safe and reliable online lending system of B / S mode.At present,the development tools of P2 P lending system include java,ASP,PHP and so on.The databases that can be used are ORACLE,SQL Server,MY SQL and so on.In this paper,the existing model of P2 P lending system is analyzed.Using Spring Boot as the framework,Java as the development tool,and MYSQL database,the P2 P lending system is designed and implemented.First of all,this paper studies and analyzes the related technologies of designing P2 P lending system,and introduces the system architecture in detail.Secondly,the paper analyzes the demand and related function modules of P2 P lending system,including the feasibility of P2 P lending system,the front function module and the back function module.Then the architecture,function modules and database of P2 P lending system are designed in detail.In order to clearly show the relationship and execution order of each functional module,the timing chart of front-end user login function,user loan function,user investment function and loan management function is designed respectively.Finally,it realizes the functions of the front and back of P2 P lending system,and test and verify each function module.P2P lending system is divided into two parts: preprocessing and post processing.The front desk function module mainly includes my financial management,my loan and membership center,etc.The background management function module mainly includes loan management,member management and fund management,etc.Among them,the main function modules are designed by time sequence diagram.The design of P2 P lending system based on B/S three-layer network structure has good advantages.It can better realize the interaction between the client and the server,and the stability and reliability of P2 P lending system has also been improved.At the same time,the system model has an important impact on the development of P2 P lending system.With the distributed model,the logical boundaries between the layers become clearer,and the data model and the business model develop from the previous coupling to decoupling.
