The Design And Implementation Of A J2EE-based Web Exam Pool Background Management System

With the information and knowledge economy era, all walks of life are a large number of used information technology program to replace some manual operations. Practice shows, information technology solutions to the industry to bring enormous changes, not only simplifies the business operations, but also improve the efficiency of the industry. Also in the education industry is no exception, the education sector is not only the introduction of information technology solutions to facilitate teaching management, and also to provide a new mode of teaching. From that point, I raised a web background management system based on J2EE technology, full use of AJAX technology to improve customer experience, and the use of access control technology to enhance system access security.System uses the B / S mode layered architecture, choose to use the Java language as the development language. Follow the ideas of software engineering, first of all needs analysis, the use of UML modeling techniques abstract use cases, and further to the overall system design, architecture design. And then detailed design the login and logout module, basic field module, audit module, permissions modules, system maintenance module. Combined with the interface and the database needs to do the design, and proposed techniques to beautify a page using AJAX to improve user experiences on the program. Part of the system implementation, but also some common features of each module, such as editable forms, AJAX paging, tree navigation, a detailed analysis of the key steps of which were explained.System uses the industry's common struts2 + hibernate + spring three J2EE frameworks and JQuery library implementation of AJAX functionality. Practice shows that the system has good efficacy and safety, is an example of J2EE systems.
