Design And Implementation Of Geoscience Online Learning System Based On JavaEE

In today's rapid development of this communications network era,it is very meaningful that to incorporate modern information technology into the traditional discipline of Geology and make it full of new vitality and vigor.The Geoscience online learning education system is a learning and teaching system software based on the daily learning and communication needs of students at the University of geology.The learning system is designed to provide system users with convenient,fast and innovative Internet learning,create a better learning environment.This paper combines with the current content of learning and management of geosciences knowledge,described in detail on the differences between the different roles and the various functions of each subsystem.This paper combines the current content of learning and management of geosciences knowledge,and on the basis of extensive literature review on the domestic analyzing the development situation and development trend of the online learning system,designs and develops the geoscience online learning system based on JavaEE.The development of the geoscience online learning system is carried out in the MyEclipse environment,uses the SSH2(Struts+Spring+Hibernate)application architecture.And combined with the jQuery framework to achieve the front page and background server data exchange.To meet the needs of different users,during the system design and the system function realization of geosciences online learning system,the users are divided into administrators,teachers,students.Taking into account the subsystems are independent of each other,to avoid the same factor data cross use etc.The system is divided into six subsystems,they are user online experience subsystem,online examination and evaluation subsystem,online video learning subsystem,online interactive subsystem,system management subsystem and curriculum data management subsystem.The geoscience online learning system is designed to present a user-friendly learning path that is user-friendly and easy to use.On the basis of this,the system completes the in-house search function with the support of Lucene architecture,andachieves the intra-system recommendation function under the support of improved Apriori algorithm.After the design,the system has been tested on the function test,performance test and system compatibility test.The result shows that the system is safe and reliable,and can realize the normal function and run safely and stably.To sum up,the development of geoscience online learning system is an attempt to the development of geography education information,integrates the modern education into the traditional geography education,realize the educational modernization of traditional advantage.
