The Design And Implementation Of ESB Based SOA Framework

Service-Oriented Architecture (SOA) has gradually become an architecture that is suit for modern enterprise. Its main idea is packing the enterprise's business function into standard services using open standards. Those services called each other through interfaces that are explicit and independent of realization. The services are also loose-coupled and called through transparency and interoperability of communications protocol.Enterprise Service Bus is a standard integration mode between loose coupled services and applications. ESB includes necessary fundamental components for implementing layered structure of SOA.Introducing ESB into SOA, and implementing the intelligent manage of different services, solved the problem that SOA ask service protocol and lactation transparent.We introduce ESB into implementing layered structure of SOA, based on principles for implementation of SOA and combined with enterprise service bus. We refer the materials about implementing layered structure of SOA. We cancel the complex Web service registration center by using Servlet and configure file. We study and implement a light weight SOA framework based on ESB. We could use simple HTTP protocol to access all services. So, it provide a flexible architecture for enterprise application, make application integration easier and improve the reuse capability.According to the characters of general applications, the paper divided ESB-SOA into 6 layers: Customer layer, services' request-processing layer, business-processing layer, services layer, service-components layer, database layer, which provide a simple model for system quickly implement.
