The Study And Application Of SSH Technology On Equipment Defect Management Systems

Equipment defect management, which is a significant constituent part in themanagement of equipments of hydropower plant, is an important measure to ensurethe health level and the safety of generating equipments and improve economicbenefits of generating. There exist shortcomings in existing management ofequipment defect, such as delay in the speed of the response to information, laggingmethods of information exchange, poor sharing and low capability to processintegrated information.Focused on above-mentioned problems, three frameworks of Struts, Spring,Hibernate （SSH） are researched, the effects each framework plays in equipmentdefect management system are analyzed in detail and a universal architecture isdesigned by integrating the three frameworks. By using Struts to build presentationlayer, using Hibernate to build data persistence layer, using Spring to build businesslayer and combined with the design principles of Spring’s dependency injection, thecoupling between main components in the system becomes loose dynamically.Adopting the idea of AOP (Aspeet Oriented Programming), Asynchronous TransferMode is added into the application business of the management system to solve theproblems that can’t be solved in traditional ways, like getting information accordingto the needs and asynchronous transmission. Finally, the design of the framework isachieved by using a practical application. The result of the development shows thatthe whole system is low in coupling and high in the reusability, the expansibility andthe transplanting of components。The design pattern and the framework technology are important technologies inJ2EE, so almost all the framework technologies use one or more design patterns, andit can improve production efficiency of software. How to choose the framework andbuild suitable architecture for enterprises and make every application layer interactwith each other in loose and coupling ways bring us a lot of difficulty. Combined withthe current development situation of multi-layer architecture in Web applicationsystem, Spring and Hibernate frameworks are introduced. Spring, a lightweight J2EEapplication framework, is built to solve the complication of developing applicationprogram in enterprises. Hibernate, an open-source persistence layer framework,reduces the complication of database development and makes the system have better capacity and capacity to transplant. and the problems that can’t be done in traditionalsystem, like getting information according to the needs and renewing informationpartly, are solved.
