| In order to meet the changing demands of enterprise business,IT sector has to provide the enterprise with new business solutions in order to deploy rapidly new corporate strategy in the enterprise.When business demands changes,IT is able to response rapidly.But the traditional business solution is unable to meet this demand. In that case,The best solution to solve these problem is to ensure the new solutions that can meet the following changing business demands.So IT sector has to search a new EAI solution to assure the flexibility of business,when it changes,IT support structure is necessary to quickly adapt to this change.Service Component Architecture(SCA) specifications has introduced the conception of "Service Component",brought out business function is provided as a series of service components,which are assembled together to create solutions that serve a particular business need.These composite applications can contain both new services created specifically for the applications and also business function from existing systems and applications,reused as part of the composition.SCA provides a model both for the composition of services and for the creation of service components, including the reuse of existing application function within SCA compositions.SCA is a model that aims to encompass a wide range of technologies for service components and for the access methods which are used to connect them.For components,this includes not only different programming languages,but also frameworks and environments commonly used with those languages.For access methods,SCA compositions allow for the use of various common use,including,for example,Web services,messaging systems and Remote Procedure Call(RPC).Therefore,the proposed conception of service component improves business solution and makes the EAI more flexible.Based on the SCA,this paper studies emphatically service components technology,and provides a new enterprise application integration(EAI) solution with software development industry.Thus,only by reusing as much existing function as possible can improve IT efficiency and adaptability,Shorten the software development cycle and reduce development costs.The speed to update Applications system can not keep up the pace of the speed of business change;it has become a key issue to search new enterprise application integration(EAI) solution in the software industry.The paper studies service component technology and SCA assembly model, analysis the assembly process of the SCA service components,builds a platform for the development of SCA service components,and in the end gives the Spring implementation model of the SCA service components.This development model has greatly enhanced the flexibility of the application system integration,it has made useful explorations for applications development and enterprise application integration based on the SCA service components,and it has achieved certain results. |
