Design And Implementation Of Distributed Service Framework For Land Resource Archives Based On SOA

Land archives have a high value,the Ningbo Municipal Bureau of Land Resources and subordinate counties have established their own file System.These systems have different technical structure,resulting in a multi-point distribution of archival global data and no unified logic structure.This situation brings great difficulties to whole city archives data interoperability and integration.Based on the requirement on the integration of archives System of Ningbo Land and Resources Bureau,this paper designs and implements a lightweight distributed file query service framework based on SOA.This paper implements the file management system on the basis of the framework.The System is actually used,the effect is good.Through studying the relevant technology of the SOA and the implementation of other archives management systems,this paper designs and implements the important core components of the architecture: Service Center and Service Gateway based on Zookeeper.This paper using Zookeeper to maintain the consistency of service data in distributed environment.Based on the service gateway,this paper realizes the file query service discovery,routing,load balancing and service governance,and finally achieves high availability of service.The distributed service framework publishes file data in counties and other business systems into Restful services for data integration.This article mainly solves the following three problems: The first is to solve the county and city archives data interoperability access,providing the city's land file unified query interface and achieving a functional integration;Secondly is to solve the data integration issues between the file System and other business systems.It improves the efficiency of filing archives;Lastly,based on the distributed service framework,this paper realizes the scalability of the file System.Through the registration,discovery,routing and combination of service,the System can easily access the archives of the lower county.
