Design And Implementation Of Open Platform For Financial Services

Because Internet technology has an open mind,it is changing with each passing day,affecting all aspects of everyone's life.The open mode represented by "platform opening,value-added profit" occupies the mainstream of today's market.Of course,with the profound change of economic operation mode and enterprise behavior mode,the Internet wave radiates to the electronic banking market.If a bridge can be built between financial products and sales channels,it will break through the restrictions of regional and single product export.Because the bridge delivers rich and high-quality products,integrates most financial products and services resources in the market,and opens them to bank customers and Internet financial companies,it contains a very broad market prospects.This paper mainly discusses the open platform for financial services based on Spring,and describes in detail the business logic needs of customers.In order to meet the existing known needs as far as possible,a strong expansibility,low coupling and high cohesion financial platform system is built.In this paper,the system platform as the starting point.First of all,this paper study the current situation of the Internet financial market at home and abroad,and then as a background to study the business needs of the financial services open platform.Under the abundant development background,this financial platform system is built to show the actual significance of market value.Firstly,this paper introduces the related technologies used in the system development,including Spring,MVC,Mybatis,etc.It describes the important components of the system,and elaborates on the development environment,the framework of the system and the choice of the system server.The paper then analyses the business requirement scenario of the financial service open platform,starting with the overview of the overall business needs,in order to grasp the overall business logic.Then the specific business of customer demand is analyzed by activity diagram,and the requirement model is built by use case diagram,and the specific components of each functional module are designed.Finally,the data is modeled by entity relation graph.Requirement analysis leads the development direction,concretizes the abstract customer requirements,and makes the development clearer and clearer.After completing the requirement analysis,the paper carries on the systematic realization elaboration.In this paper,the hierarchical model of the system is given,and the whole platform is built on this basis.And the functional decomposition diagram is also given to divide the functional modules.According to the data modeling in the requirement stage,the implementation of database construction is introduced first,which is explained in the form of data dictionary.Then it enters the code development stage with the designing of various classes and methods,to complete the inter-class messaging.The core controller runs through the whole system transaction process and is the key module of the system.This paper focuses on class diagrams,introduces the various classes in the code.And then use the time series diagrams as the center to introduce the dynamic relationship between classes and the call relationship.Finally,an open platform for financial services has been successfully built,and detailed test case design has been carried out to ensure that products can correctly reflect customer needs and achieve product launch.The system deployment and test show that the system function modules run normally,and make the system have high scalability and reusability as far as possible under the condition of meeting customer needs.This paper takes the construction of an open platform for financial services as an example,and studies the significance of the platform in the market.It has certain reference significance in using mature frameworks to build systems,study and analyze problems,propose practical solutions and integrate technologies.
