Research On Enterprise Application Integration Based On REST

With the progress of information technology and network technology,especially the rapid development of Internet,the market become more and more competitive.To improve their working efficiency and gain a competitive advantage,enterprises have to introduce various information management system.These systems usually provided by different software vendors,using different language,different technology,and different platforms.The lack of IT planning and sector centered business ideas make it difficult for the interaction between heterogeneous systems.There,"information island'" appear.The integration of heterogeneous systems had been developed from point-to-point to middleware,which is tightly coupled.After years of exploration and improvement,SOA has been gradually accepted by most of enterprises.Although the current popularity of SOA solution still use the traditional WS-*technical implementation,as the mobile terminals,mobile devices,web applications within the enterprise grow,enterprise mobile informatization has be vividly portrayed,enterprises urgently need a simple,flexible,fast integrated architecture to meet the needs of rapid change.Also the match between REST and web application in such aspects as design concept,technology,at el,make it more advantages to implement SOA based on the REST.In this paper,we introduced the concept of REST and SOA integration at first,then compared the traditional WS-*technology with REST services technology to show the advantages of REST services.After that we expounds the necessity of the combination of SOA and REST,and put forward a integration solution,which use SOA as the integration architecture,REST as the integration technology and ESB as the integration medium.We can also name the solution as service oriented integration solutions based on REST.In line with the solution,the rest-based service oriented integration process model and integrated architecture has been proposed.At last,the key technology in the integration was introduced,to guide the landing of the solution.Finally,based on the background of the present restaurant O2O boom,the NYC Chinese fast food chain was selected as the research object,and the service-oriented integration solution based on REST was chose to solve the current integration problems.The case in accordance with the integrated process model,was analyzed in detail from business modeling,service modeling to the platform realization.Then we demonstrates the simple code implementation of RESTful Web services and service orchestration.In this paper,the integration of the reference model for enterprise application integration provides a reference for integration.Using REST technology to realize the interoperability and data sharing between heterogeneous system,make full use of the legacy system and improve the reuse rate of IT asset.At the same time new applications can flexibly and quickly build.Which meet the demand of enterprise applications,and seamless link with legacy systems.
