Student Management Information System Based On The Mvc Design And Realization

As the rapid growth of educational system in China,people now have more demands on teacher's knowledge level and the way of teaching method including both hardware and software.However,the management of teaching method receives more demands than others.In order to satisfy those demands and provide relative services for both teachers and students,as well as to create a high efficient and convenient environmental in campus, a wide range use of Web system for all college students becomes a must.Based on the modem technology of MVC and J2EE study,Multi-layer structure of J2EE which has been realized by FreeMarker,WebWork and Spring has been brought forward,the management information system for all college students which based on MVC has been designed and implemented in this chapter.This will use for reference for other Web Applications system based on J2EE platform.In the process of system development.controller is utlized to separate model and view in order to effect loosely coupled layer to improve the system's flexibility,reusability and maintainability. System is controlled by WebWork while data or status and logic process are enforced by"Action".Default interceptors and interceptors were used to decide whether or how to carry out the"Action"before"Action"was executed. Interceptors were in use to complete a series of security,and logs and calibration work.To receive a dynamic data from WebWork is by using the technology of FreeMarker in the performance.Many macros were defined to unify the style of system pages,reuse of code duplication and improve efficiency. A light weight tool called''Spring loc Container''is used to manage"Service"in the business logicat layer. And JDBC Template is used for blocking some complex areas from database and decrease the complexity of its process.In this paper,the work of design and implement of teaching information management subsystems,school management subsystems and attendance managemem subsystems is completed . The system has been preliminary run in campus by testing and debuging.The result indicates that the direction of this technology study is correct and the design of this program is essential.
