The Research And Implementation Of Vehicle Parts System Based On The Struts And Persistence Layer Technology

Continuous expansion of producing scale, frequent change of producing process and fast development of products make primary data of parts list change usually, so that it is hard to perform statistics of data and production control, the coordination among departments is difficult and the work efficiency is low. Thus, it requires the enterprises to use information technology to change the present situation of management urgently. Considering rapid development of internet and update technology of facing to object at present, after satisfying clients'demands, we should also consider the ability of expansion, the ability of maintenance, the flexibility and the developing rate of system, and design model can be well used in constructing the system. We can wholly plan the design of system structure and the system function, which can make the current system and further developed system perform well.According to developing practice of application system in an enterprise, combing with present development status of multi-level structure, the paper deeply analyzes MVC design model and Struts developing framework and puts forward developing framework of Web application system with multi-level structure on the basis of Struts framework. After introducing the persisting layer, it discusses characteristics and advantages of OJB as O/R Mapping products in lasting technologic system, and also discusses the methods about how to apply MVC design model to the project development combing with Struts framework. Adopting this design, the system becomes more flexible and it is easier to update and alter system. By studying main technology about developing Web and designing framework, aimed at the shortage in the traditional developing mode and framework design, and combining with the respective advantages of Struts framework and OJB technology, this paper makes the technology of developing framework with multi-framework come true. And the paper introduces the concrete design about the system, including demand analyses, data-base design, system structure, the concourse of function module and so on, and then introduces the method how to realize them in the concrete project. In addition, by applying it in the vehicle parts system successfully, the paper validates the feasibility and mighty function of the technology. At present, we have completed coding and testing on the vehicle parts system, and we are checking and trying to run. According to relative feedback from clients, the system reaches the preconcerted objective, and the effect is right. It is greatly praised by the clients.
