| With the development of software technology,especially the appearance of Web Service a new method was put forward and rapidly developed called SOA(Service-Oriented Architecture).SOA will be able to help IT organizations to face the complex challenges, which has the best application foreground.It is a kind of applied programming architecture and a method of constructing described system,all of its functions can be defined as the isolated services which have definite and allocation interfaces,it can form the process flow by allocating these services with the well-defined order.SOA can resolve all of the above problems,such as the distributed software,application integrations and different platforms, protocols and devices.The paper has designed and analyzed Service Oriented Architecture on the base of requirement of the government functionary management information system and standard of SOA,and has suggested a SOA framework with Web Service and ESB,then has developed the platform use this framework.The main studying works and innovations that the paper has concerned about the item are:Firstly,the paper discussed the technology of Service Oriented Architecture,and the relationship between Enterprise Service Bus and Service Oriented Architecture.Then it has suggested a kind of model of Enterprise Service Bus based SOA and Web Service(ESB Based SOA and Web Service,EBWS model).As a bridge between requester and Web Service, EBWS manages the interface of Web Service.Secondly,the paper has studied the theory and related technologies about the solution of government functionary management information system.On the base of the concept and fundamental of SOA,it has suggested a framework about Service Oriented Architecture combining J2EE,EBWS and Web Service,which has been named JEWS(J2EE and ESB Based SOA Framework,JEWS frame),JEWS has many characteristics,such as Web transparency and loose coupling.Thirdly,on the base of analyzing business requirement,the author has participated in designing and implement the setter scheme of technology of the government functionary management information system.This scheme which is a combination technology framework combines the technologies of Web Work,Spring and Hibernate,gives full play to their respective strengths,resolves the related problems being brought by the complex structure during the building of Web Application System.At last,with the framework of JEWS and WSH,the author has put the SOA-based Enterprise Information Solution into practice and has participated in designing and developing the government functionary management information system based on SOA according to business needs,which is using now. |
