Design And Implementation Of Dynamic Routing Insurance Enterprise Service Bus

With the continuous development of insurance business, the application association of insurance enterprises’ internal information systems has become broader and closer and information transfer among different systems has been more important. The logical diagram of different systems normally forms the reticular structure eventually and inter-system coupling increases obviously, which means a slight move in one part may affect the situation as a whole. Therefore, the key issues of enterprise information system launch have been developing Enterprise Service Bus with service routing technology to conduct system integration, reduce coupling and share information.This thesis analyzes the current domestic and foreign research situation of enterprise service routing technology and briefly illustrates common architectures, design concepts and data models of service bus. This thesis also analyzes and compares the advantages and disadvantages of the current mainstream service bus products in the market through product survey and research. Moreover, this thesis sets forth the key technologies used in service routing systems based on insurance business metadata, mainly including insurance business metadata analysis, dynamic routing technology and template technology. In addition, this thesis conducts demand analysis of service routing system and introduces system design target and function demand, based on which the thesis also designs system overall architecture and workflow and further detailed designs and realizes a service routing system based on insurance business metadata. This system’s modules primarily consist of ESB operation domain, service management domain, system management domain and security domain and the system’s function mainly includes service access, service registration, service dynamic routing and format conversion and so on. Among the system functions, service access responds to service request, service registration dynamically loads service under runtime environment, service dynamic routing dynamically controls and processes service flow and response, and format conversion unifies data models inside the system based on metadata. This thesis describes the typical practical application environment of system, tests the response performance and service dynamic routing and displays the actual system application effects.The online operation of the system shows an apparently good effect, improves development efficiency, reduces the development workload of interface layer and routing layer, realizes the dynamic routing function of enterprise internal service, reduces inter-system coupling and improves the stability and convenience and inter-system operation. The system also unifies enterprise internal data models and lays a solid foundation for next step big data analysis. The system’s running online has passed tests of large-scale online activities, supported access requests with high concurrency and large data volume, comprehensively sorted out services provided by various systems inside enterprises, standardized access services of various systems and achieved the system design target.
