The Research On Key Technology Of Online Business System Based On JavaEE Platform

With the rapid development of Internet technology and the widespread of Internet in China, a new consumption of trading pattern has gradually become popular in people's daily life. It is the online trading system. More and more people who stay at home choose shopping online. This is one of the most powerful proofs meaning the steady development of e-commerce in China. Although e-commerce in our country has started for not very long time, it grows fast. So, based on relative key technology of online business system, a design implementation focused on JavaEE platform is put forward in this paper.MVC (Model-View-Controller, the model layer-the view layer-control layer) is a design pattern which separates the application, processing and output compulsively. MVC divides the application program into three core applications:the model layer, view layer and control layer. It can be used to perform different tasks respectively. The system is carried out under the guidance of the MVC implementation.Among many MVC frameworks, Struts framework is the earliest and the most widely used one. Struts2, based on Web Work core is now the most commonly used in Struts framework. Interceptor is used to handle users'requests, so the users can separate the business controller from ServletAPI.In addition to Struts2 framework, the Spring framework and iBatis technology are also integrated in the system. Spring is the most popular lightweight development framework of JavaEE. It can also complement the other technology components of JavaEE. So programmers can make application development easier and at the same time, more reliable. iBatis is the data map, with it SQL statement results can be mapped to relative parameters.This issue is mainly research on realization of online trading system which based on the above technology. The research is also based on the B/S model which is used widely at present. By the analysis of the detailed requirements of the system, we can divide this system into two major roles:the system administrator and network users. Both of them have separate powers and operations management. According to their different operations the system can also be divided into multiple functional modules.Oracle database and the Tomcat server of Apache company are used in system's realization. Besides, Java, JSP programming languages are used in the Eclipse environment based on Windows XP operating system. Through a series of works such as system demands analysis, design, coding, test design, etc, this system basically realizes the function and has good scalability.
