Shanghai Bell OA Application Integration Solution Research And Implementation

Along with the development of enterprise information, business leaders pay more and more attention on information technology, and also more and more dependent on information systems, Shanghai Bell develop or purchase the appropriate business IT systems to fulfill the internal departments need, these systems are often lack of adequate information exchange, resulting the "islands of information" problem, it is more and more obvious, such as information and data cannot be shared, duplication of information storage and so on. The Bell CDC used to some conventional office applications, the application and approval process is not standardized and flexible, and lack of expansibility. Regarding to the office automation requirements for business and lower the implementation cost if possible, it would be more appropriate to use the lightweight open source solution to implement. So to fulfill the company’s faster, efficient, lower cost application integration solution, this article tries to implement Bell OA application integration solution based on lightweight Mule ESB and Spring framework.The article analyzes Bell’s business application integration system and the current status based on the existing application systems cannot meet the business requirements and the OA demands. After the analysis and investigation, then decide to use the Mule ESB EAI/SOA solution to implement the OA integration application, and it basically meet the needs of enterprise OA applications.The article first made simple introduction on the EAI/SOA technical concept and development tendency, then introduce the open source Mule ESB product in detail and the integration solution with Mule.After analyzing the OA integration requirement, the article described the total design solution based on Mule ESB and combined with the lightweight Spring framework.Finally, the article described the implementation according to the specific characteristics of Mule ESB and Spring framework, developing the workflow thru Mule Studio which allows you to achieve rapid development and implementation via a visual way configuration and orchestration, sthe core business logic will be completed by the Spring and well encapsulated in the mule process. The article took an OA leave apply process implementation as an example to show you the advantages in drag and drop visual development and well-integrated with open source framework like Spring, dynamic configuration, content routing, internal webservice integration.
