Design And Implementation Of Topology Management In Network Management System Of Electric Vehicle Power Station Based On Flex

Today, the development of the Internet is rapid.Web applications are paid more and more attention by enterprises.Web applications developed by the architecture of J2EE are the major solution to the construction of enterprise information.As the development of J2EE,many framework in web development appeared such as Struts,Spring,Hibernate and so on.The emergence of framework allows developers to focus on the software development of business, improve the quality of the program code,and follows the rapid development of enterprise business needs.Also, it affords more convenient for software reuse.As the development of Web system, the well interactive of system is the new need. Rich Internet Application (RIA) technology, complies with this requirement.It brings good experience on operation and visual to users.Flex,a technology of RIA, is matured and more perfect. Flash files compiled by Flex applications is accepted by Flash Player, therefore, to users of most browsers,they can use the program developed by Flex without installing additional client support.In this paper, I firstly study and research the technology of J2EE and Flex.I make a need analysis of the topology management of the Network Management System for electric vehicles.Based on this, I do the overall design for topology management including functional design and database design.In the detailed design of the topology management, I make the hierarchical design of the system, and complete the design and implementation of each specific.View layer is developed by Flex, and persistence layer is developed by Hibernate. The persistence layer interface is injected into the business layer by Spring. I make the design and implementation of Web application system using a combination of Flex and J2EE. Finally, I test the system.The system has been applied in actual operations.Topology management module of the Network Management System for electric vehicles based on Flex and J2EE afford a visualization platform for people responsible for monitoring power station network infrastructure and meet the user’s needs in functions and operations,also make a reference for the related application development.
