Research And Implementation Of Campus Affairs Self-service Guide Service System Based On J2EE Technology

In the 21st century,with the continuous development of infonnation technology,people's access to information and information has not been limited to paper documents Nowadays,people can access various resources quickly and easily through the network.As the scale of education in various universities continues to grow and develop,the various types of affairs involving teachers and students are becoming more and more numerous,and the process of doing things is relatively complicated.Based on the actual business needs of the self-guided service system for campus affairs in many colleges and universities in Tianjin,this paper takes Tianjin Vocational and Technical Normal University as the research obj ect and develops a self-service self-service that is universally suitable for the current situation of colleges and universities based on the B/S model.system.This paper first discusses the background of the development of the subject,and briefly introduces the key technologies involved in the development of the self-guided service system for campus affairs.It analyzes the functional requirements of system development,non-functional requirements such as system performance and product concurrency,and discusses the system.Architecture design,overall functional architecture and database ER model,data table structure design,in the system design process,the Power Designer tool is used to design the database ER model of the system,the relationship between entities is described in detail,and the data table is created.The campus affairs self-help guide service system adopts B/S architecture,selects JSP,Servlet,JDBC for system development,MySQL to implement background data management,and J2EE technology as system development tool.The structural model of the system is determined according to the MVC design pattern.The timing calling method and business processing class of each functional module are designed in detail,and the program code used for each function is written,and the system function interface is designed.
