Design And Implementation Of Online Examination System Based On SSH Framework

Computer network technology has been widely used in modern society and has promoted the transformation of networks in various industries,resulting in tremendous changes in the education industry.Online online examination mode has irreplaceable advantages and gradually became an important measure of new-type education measurement.It has been more and more people's attention and recognition,and has become an important form of assessment in education,national defense,finance and other industries.The online examination system is free from constraints of time and space,can evaluate the scores fairly and fairly,and saves manpower and material resources in the examinations such as the rollout,invigilation,marking,evaluation,etc.,and the storage and transmission are more convenient and become an important tool for the examination.The core function of the online test system is the smart test paper function,which is based on a set of educational measurement coefficients,calculated by a specific algorithm,and selected questions that meet the requirements and automatically combined into test papers.The intelligent grouping function not only needs the characteristics of quick selection of questions and the generation of test papers,but also the quality of test questions and the fairness and fairness of the test.Based on the analysis of the existing theory of online examination mode,this paper combines SSH framework and real-coded genetic algorithm,and studies and implements an on-line examination system based on SSH framework.The system is expected to simplify the current workflow of all kinds of examinations,save manpower and material resources,reduce the input of schools for examinations,and then promote school work efficiency,and further deepen the level of education information.The main work and innovation of this article are as follows:1.Study the basic theories of the online examination system and composition algorithm,and summarize the development status and application practice at home and abroad,and discuss several current mainstream algorithms to provide relevant theoretical knowledge for the requirements analysis and design implementation of the system.And technology foundation.2.Analyze the SSH framework in Java development,and deeply study the role of the three-tier framework of Struts2,Spring5,and Hibernate5 in system development,and apply these key technologies to the micro-learning system.3.According to the characteristics of the online examination system,this system is studied from both functional and non-functional requirements,and the system functions and user groups are defined.The online examination system is designed,each function flow and corresponding sequence diagram are given,and the database table required by the system is established.4.Researches and studies common grouping algorithms,and analyzes the requirements of the intelligent testing function of the online examination system.It is determined that real-coded genetic algorithm is used to implement the intelligent grouping function of this paper.This article discusses in detail the process of using intelligent algorithms to achieve smart test paper function strategyThe system was finally launched using JavaWeb technology,SSH framework,and MySQL database.Its intelligent group function selection genetic algorithm is designed and implemented.
