| Record2.0is an ETL (Extraction-Transformation-Loading) tool of the Enterprise, based on service components. Record2.0has no visual interface, and the coupling degree between the components and process is high, and it is inconvenient to do process definition and task scheduling. To solve Record2.0deficiencies and improve the product’s versatility, this paper presents a topic of management of control workflow platform based on extendable component. The platform is a supported product, and the main users are the maintenance personnel. The platform has good scalability and friendly web visualization interface, improving the maintainability and reducing using difficulty.To focus the target of the project, this paper analyzes the requirements of the platform and designs the overall structure, including Web Server subsystems and Control Center subsystem. The main functions of Web Server include the web visualization, the request dispatching, data processing and forwarding messages; the main functions of Control Center is to do data persistence, as well as monitoring the workflows and task scheduling. Then some key technologies are described, including ExtJs, Struts2, Spring Framework and COPART-MACO (Component Package of Real-Time Application Process Management and Communication).In terms of the design and implementation of the platform, this paper mainly analyzes the service component management, the design and implementation of Web Server subsystem and the file system of Control Center. The analysis of service component includes the definition of some concepts, expandability and Plug-in implementation specification. The discussion of Web Server subsystem includes the implementation of web view, request dispatching, logic layer and data layer.Each part of this Management and Control Workflow Platform based on Extendable Component has been tested, and the results achieved are consistent with the expected results. In the end of this paper, the summary and outlook are discussed about the project, and the next step of the platform is to improve the convenience of the operations of the Web interface and the versatility of the platform. |
