Design And Implementation Of Educational Information System Based On JavaEE

With the rapid development of the Internet,the school in the academic affairs,daily work management and other aspects of the growing pressure,the problem is more and more obvious,educational administration work as the most critical part of the university education system,an urgent need to use technology Means to solve the daily work of many problems.I used my own work requirements to participate in the research,design,and development of the system,including the system's research background,status quo,usage technology,requirements and system design,system implementation and testing,etc.Shiro authorized certification,used to handle identity authentication,authorization,enterprise session management and encryption,using MemCache to achieve distributed memory object cache,use lucence full-text search,space for time,full-text indexing of files,character streams that need to be retrieved,Especially in class management,the design of intelligent class scheduling based on genetic algorithm is studied.The modules involved in this paper include six aspects,specifically including: student management module,teacher management module,class management module,document management module,appointment test module,teaching resource management module.The main innovations include the following aspects.The first adopts the MVC model,uses the SSH framework to improve the system's web hierarchy,provides deep decoupling,facilitates system development and maintenance,and uses MemCache technology for caching to improve system access efficiency.Second,in terms of class scheduling algorithm,referring to the currently existing class scheduling algorithms,combined with the actual situation of the school,they summed up a set of scheduling algorithm to achieve,and finally for each module business process analysis,use case analysis,page Design,function implementation,module testing,complete the business relationship between the various modules of the educational system and the interaction of data.The development of the system and on-line,not only to the daily work of colleges and universities to save a lot of manpower and materialresources,but also improve the school's daily educational administration capacity.In this paper,the educational administration system has carried on a large number of business needs research and analysis,based on the facts,through the status quo of the major colleges and universities and educational management system as the starting point,targeted the integration of resources in the convenience of teachers Work and students under the premise of learning,built a java based on the educational management information system.
