The Design And Implementation Of The System Of Dianping Receipt ThirdParty Service

The Receipt Service of Dianping Group Buying Website is quite large and complicated. The system has so many functions that it gets a high degree of coupling. Different thirdparty servers may depend on different APIs, this contributes to lower cohesion of the system. What’s more, several applications share to access to the database, which brings insecurity. Against this backdrop, we established a Receipt Thirdparty Service system. On one side, we can reduce the coupling of business logic and make each module highly cohesive. On another, the Dianping Group Buying system will be more extensible and be able to meet rapid developing needs.This paper carries out research work around the design and implementation of the Receipt Thirdparty Service system.First, we introduce the technology and framework involved, including Spring, Struts 2, iBATIS, Quartz and WebService.Next, we analyze the basic requirements of the project and get an overview of the overall design and project modules. Then expound the detailed design of the system. Based on the overall design, we finally describe the detailed implementation of the main functions.This paper mainly discusses the producing module, verifying module and refunding module of the thirdparty receipt of Dianping Group Buying. It shows the implementation of a series of operations, from producing to verifying, of the thirdparty receipt in detail.
