Employee Self-service System Based On Java Ee / Mvc Architecture Design And Performance Analysis

With the rapid development of the Internet technology, the mufti-tier Web application based on B/S has been widely used, Web applications such as online news, retail, and financial sites have become commonplace. In the development of Web application, the application development framework based on Java EE/MVC has become a mainstream. Based on this framework of multi-Web system, the methods of Presentation tier, business logic tier and data persistence tier have become variety. Despite the increasing number of Web application in use each day, little is definitively known about their performance characteristics.This paper firstly introduces the architecture of Java EE and MVC design pattern. Then gives details of Struts, Spring and Hibernate, and analyses each framework's function in Web application tier. According to the Java EE architecture and combined the characteristics of Web application, this paper designs Java EE architecture of integrating with the three frameworks. In this architecture, Struts take charge of the presentation tier, finishing page displays and responding user's requirements; Spring takes charge of business logic tier, completing the business logic and management of application programs; Hibernate takes charge of data persistence tier, completing data persistence. An example based on employee self-system is introduced to illustrate the process to build a Web System with the help of the architecture.Finally,In order to describe the performance characteristics of the system, I have Applied the queuing theory to the system. And, according to use of open source software for online testing, a model of the performance of the system has been obtained.
