The payment system provides a systematic solution for the fund flow between accounts.As the core of the electronic payment system,the accounting system carries the maintenance functions of all the core transfer services,all the account funds and flow,and almost all the payment capacity is built on the accounting system.Due to the multi-party flow of capital flow in the process of payment,it is inevitable that there will be errors in capital records due to network or system reasons,which will lead to the wrong calculation results of the accounting system bill,resulting in losses that are difficult to estimate.In order to catch the above abnormal situation in the accounting system as soon as possible,this paper designs the accounting supervision module of e Bay distributed accounting system.This module provides a friendly interface to help the company's financial staff to monitor,calculate and replay the capital business in a multi-dimensional way to verify that the completed accounting calculation is correct and the transaction amount is the same.At the same time,it is convenient for the financial staff to find out the business problems in real time and to participate in the correction of errors manually.In addition,in order to ensure the security of the transfer and storage of capital data in the accounting system,the module provides the functions of data encryption and integrity verification.The system respectively uses Angular JS and Spring MVC as the front and rear development framework,and adopts Event Sourcing architecture to ensure the business accuracy and traceability.In view of the data security,the method of DES symmetric encryption and HMAC digital signature is used to strengthen in many aspects.This paper also uses Command Query Responsibility Segregation,library partition,and Oracle distributed database to improve database read and write performance.The system has been put into operation,and the accounting supervision module has successfully improved the security of the capital data flow in the accounting system,helping the financial personnel of the company to conduct business verification,fund monitoring and locate fund problems.The system has improved financial efficiency and increased corporate earnings.
