Design And Implementation Of Online Examination System Based On Spring And Hibernate

With the rapid development of computer network technology,the increase of the type of school examination and the continuous improvement of the examination requirements,the traditional way of education has also undergone profound changes.There is an urgent need for an automated test system based on the network and the online examination system.Online examination is not only an important part of network education,but also an important part of paperless office.It can effectively avoid the negative effects caused by the subjective factors of teachers,and can improve the accuracy and scientificity of the examination.Online examination system can make teachers free from the hard works such as making questions,invigilation,making papers and so on.So teachers can concentrate on the analysis of the student achievement data and grasp the students learning.Online examination system also can improve the quality and efficiency of teachers.At the same time,it also saves resources.It is an efficient and flexible examination mode and is also the development trend of education in the future.This paper introduces the background of the online examination system,the research status at home and abroad,and the relevant technical requirements.This paper is based on the open-source frameworks such as Spring,Hibernate and so on.On the basis of a thorough study of these open source frameworks,an online examination system based on B/S structure is implemented.The paper also gives a detailed introduction to the system requirement analysis,system function design and system development.Online examination system simulates a real examination process and examination environment,and has realized the entire examination process from item bank management,auto-generating test paper,testing,automatic monitoring,automatic marking about objective questions.This paper focuses on the algorithm of automatic test paper generation.In order to overcome the shortcomings of the traditional genetic algorithm,the improved Memetic algorithm is used to improve the traditional genetic algorithm,which avoids the premature phenomenon of the original algorithm.The system has friendly interface,convenient operation and high safety.The actual tests proved that this system has a certain practical value,meets the needs of teachers on the exam,and also provides a flexible,convenient,scientific and fair examination platform for students.
