Research And Realization Of The Network Performance Management System Based On J2EE Platform

With the continuous expansion of the network in size and the rapid increasing of the network traffic, objectively it needs the network management software to ensure the normal operation of the entire network. However, the traditional network management software based on C/S model is unable to meet the changing business requirements, so this thesis presents the network performance management system of the Web way based on J2EE platform.Firstly this thesis points out the lack that the realization of the traditional J2EE architecture must depend on the support of the specific server on the basis of research the MVC model and the traditional J2EE technology, and proposes the solution of the lightweight architecture and in detail introduces some popular open-source framework technology involved by the lightweight architecture.Secondly, after describing the existing business and the design principles of the system, the thesis mainly analyzes the system requirements of the network performance management system and gives the use case diagram and the activity diagram.Then, the thesis designs a layered architecture fusing the various open source framework technology, and it makes the system not to depend on the specific container. For specific implementation technologies, the Web layer uses the Struts framework technology based on MVC model to construct the layer, and in the business layer, it uses the simple JavaBeans to realize the core business logic of the system and divides a service layer providing the operations for the upper layer, and in the data layer, it uses the Hibernate framework to realize the persistence of the business entity, and designs the interface layer providing the data operations for the business layer by using DAO model, and using Spring framework to achieve the integration of the three frameworks and realize through configuration-file form to express the dependant relationship of the various components. The practical results show that the framework of the integration of these three is not only conducive to ensure the development efficiency, but also ensures the reliability, stability and portability of the system.Finally, the thesis describers the realization of the system in detail, including the module realization of the system login, the user management, the role management, the device setting and the regional setting. In the system implementation process, we make the each layer to be interrelated through the interface under the core idea of the interface-oriented programming, such can lower the system mutually connection. When dealing with the user requests, the different functional modules correspond to the different process modules, such can enhance the readability of the code. In the display pages, we use a lot of functional labels to replace the normal website elements and Java codes, such can be easy to realize the internationalization and enhance maintainability about the system. In the practical application, the system only needs to configure the application server, and then it can be released and used.The successful application of the J2EE architecture integrating the various open-source frameworks proposed by this thesis, for small and medium-sized enterprises, has the certain reference significance on the development of Web aspect.
