Design Of Support Framework And Online P2P Lending System Based On Android

The development of the Internet and mobile Internet contributed to the generation and development of Shared economy.The essence of Shared economy is that integration of offline idle resources,and then realizing the resources sharing through the Internet as a medium.At present.Shared economic covers wide range of areas,including travelling,medicine,space,knowledge,items,and finance,etc.The concept of Shared economy implementation needs to use the platform as a medium.The platform of different areas has some function in common and personalized demand.The same function includes registration and login,the service demanders release demand information,service suppliers provide services,etc.The implementation of common functions and personalized demand needs a good framework to improve the efficiency of the development.This thesis will choose the P2P lending system as the research object in the shared economy background,improve the traditional background framework via combining with the features of the mobile terminal development.It has important significance to improve development efficiency of different platforms.On the basis of in-depth research of related literature at home and abroad,This thesis do some research on the construction of development framework.Including design patterns,MAS,breakpoint resume,etc.respectively from the persistence layer framework,the framework of security and mobile terminal support module,combined with the MVC to design the architecture,that can separate the layers effectively.realize a integration framework on PC and mobile that is simple to use,easy to maintain and expand.Then,using the framework to bulid android and website P2P lending system.Unifying Data transmission format to make controller is able to deal with mobile terminal and the PC request together;For concurrency issues caused by the huge user group of handheld devices,this thesis develops concurrent control model based on MAS to improve server dynamic adjustment ability;For the problem of failed download caused by a lack of battery power or network failure,using breakpoint continuingly technology saves the phone flow.In this thesis,the framework implemented in the application of P2P lending system,has achieved a good support for data persistence layer and solved the problem of system security to verify the feasibility of the framework applicable.the usages of framework,reduces the amount of code duplication,improve development efficiency and reduces the degree of coupling modules for easy system maintenance,expansion,fully embodies the framework of reusability.P2P lending system makes more people enjoy the P2P microfinance services,P2P as a supplement to the traditional credit lending system,is the healthy development of financisl credit market trend.
