Research On The Service-oriented Platform Of Mobile Education In Colleges And Universite

Since the 21 st century,with the rapid development of science and technology,we ushered in the mobile phone as the representative of the mobile Internet era,people are increasingly accustomed to through intelligent mobile devices to obtain all kinds of information.In the teaching of colleges and universities,the traditional teaching aids platform has been unable to meet the increasing teaching and learning needs of teachers and students.Many colleges and universities pay more and more attention to the students' learning process,pay more attention to students' usual grades,and the traditional teaching auxiliary platform can not record this information well,while teachers can not grasp the student learning situation,students can not timely feedback problems encountered.Traditional teaching support platform is often based on the PC side,because the PC is not easy to carry,will bring inconvenience to the use of teachers and students,and smart phones can always connect to the network,and easy to carry.In this context,with the help of mobile Internet technology,design and implementation of a college mobile teaching support platform is necessary.In this paper,the use of hierarchical service-oriented architecture program,to achieve the ITeacher,IStudent two mobile client and background management platform,mainly to do the following:(1)In the system architecture,the hierarchical service-oriented architecture is adopted,which divides the system into four layers: Database Layer,Persistence Layer,Business Layer and Presentation Layer,which improves the flexibility and expansibility of system services.(2)In the core technology,set up a MySQL-Redis data storage system to provide massive data distributed storage and data cache function;through the SSM framework designedRESTful style data service interface;through the Spring MVC framework will be divided into business logic;the data communication protocol based on JSON is designed,and the data format is standardized;a point-to-error detection scheme based on deviceToken is proposed.(3)Considering the security of system service,a session cache system is designed and an interface encryption scheme based on sessionid,timestamp and public key is proposed.(4)In order to alleviate the high concurrent service pressure,the MySQL database for master-slave settings and data read and write separation,ease the database IO pressure;build Nginx-Tomcat server cluster system to achieve network load balancing.Finally,this paper implements ITeacher,IStudent two mobile client and background management platform,and test the system capacity of the service capacity to verify,to achieve the desired goal.
