Design And Implementation Of Online Bank Payment System Based On Spring

In recent years,with the rapid development of science and technology,the speed of economic globalization is greatly accelerated,and the advantages of online banking payment are more and more obvious.People's demand for payment is no longer limited to the use.The online bank payment system with simple payment steps,low threshold and friendly interface has become the mainstream of online payment.However,there are still a small number of small and medium-sized banks in underdeveloped areas whose online banking payment system still stays in the traditional online banking payment level.The traditional online banking payment system,with its old functions,unfriendly interface and cumbersome payment process,also restricts the further development of small and medium-sized banks.In order to better the development of small and medium-sized banks,the design and implementation of a set of online banking payment system in line with the current payment habits is also an urgent need of some small and medium-sized banks.Based on the above background information,this paper investigates the current information development status of small and medium-sized banks in a certain region of China,and analyzes and designs an online banking payment system in line with the current development of the small and medium-sized banks according to the actual business function requirements of the bank.The main contents of this paper are as follows: firstly,this paper reviews the research background and significance of the topic,then analyzes the current mainstream online banking payment system,gives the demand direction of the small and medium-sized bank online banking payment system,and then analyzes the related theories and technologies that may be involved in the development of online banking payment system,including spring framework technology Oracle database technology and XML technology.Next,from the aspect of demand,this paper expounds the general overview of the system,the business process of the system,and analyzes the functional and non-functional requirements of the system.The system should have the functions of managing the user's account information,processing the transaction requests such as payment,refund and query submitted by the user,and processing the accounting information.Then,on the basis of requirements analysis,the system architecture and network hierarchy are designed in detail,and the business process of the system is sorted out.Then,according to the difference of functions,the system is divided into modules,and then the system is designed and implemented based on the requirements analysis.Secondly,the database system is designed and optimized according to the needs of the system and business.Finally,this paper tests the online banking payment system.According to the testing principles of software system testing,this paper gives the test environment of the system test,and then tests the test scenarios of the given system test cases,and then carries out the pressure test on the system.After summarizing and analyzing the test results,the test results show that the designed online banking payment system has perfect functions,simple operation,simple interface,and can well meet the needs of online banking payment business of small and medium-sized banks in a certain region.
