| The change of payment mode and the change of commercial society are developing synchronously.From barter at the beginning to currency as the medium of exchange.The form of money has developed from physical currency,metal currency and substitute currency to credit currency.With the progress of information science and technology,electronic money has been developed.Electronic money is a new type of credit currency and an invisible credit currency.The payment methods of electronic currency include bank card payment,mobile phone payment,Internet payment,electronic wallet payment,etc.Based on the business needs of a financial institution,this paper uses JAVA technology and development framework play to analyze,,design and develop the demand of payment back-end management system.Payment background management system mainly realizes three business processes,which are closely related and interlinked.One is the account management process,which mainly manages the cash flow process of customer payment.The second is the process of commodity management,which mainly manages the process of data transfer such as the definition,pricing and authority of commodities.Third,the order management process,mainly manages the order generation,settlement and delivery of data flow process.In the process of design and implementation,according to the relevant theories of software engineering,this paper proceeds step by step.In the stage of requirement investigation,the high-level and all-level personnel of the enterprise are investigated in turn,and the business requirements of the enterprise for the construction of the system are gradually clarified,and the prototype of the system is designed and completed.In the stage of requirement analysis,guided by business requirements and system prototype,requirement specifications are compiled.In the system design stage,according to the business requirements,system prototype and requirements specifications,the detailed architecture design of the system is completed,and the related graphical tools are used to show it.So far,all the work in the stage of project development and design has been completed,which lays a solid foundation for the realization of the system.In the system implementation stage,JAVA technology is chosen as the main development technology;JQuery development framework is used in front-end development,Play development framework is used in back-end business development,and My SQL is selected as the database.In the system testing phase,through the application of a series of testing methods,it ensures that all business processes in each business scenario can meet business needs.In the development process of the system,the open-source play development framework is used as the main framework,which meets the performance requirements of high concurrency scenarios,improves the development efficiency,and makes the system have good scalability and scalability.The system basically meets the needs of customers,achieves the functional and non-functional needs of customers,and achieves the landing of enterprise development planning. |
