The Development And Realization Of Iron Ore Analysis Management System Based On J2EE Framework

With the Web technology developed quickly, traditional management system based on Client/Server model can hardly meet the requirements of enterprise-level application, thus Web application based on Browser/Server model become more and more popular as a technology of web application, now many application systems are built on the basis of the Web.This system use Struts, Hibernate and Spring as the development frameworks. Struts is designed to improve user experience, providing user with a friendly operation interface, processing the foreground operation of the system. Hibernate takes responsibility to read from and write into database as background persistence layer, accomplish the task of interaction with data. And spring becomes the connection of foreground business and background logic, take charge of controlling operation that bring data from foreground to background, and then background to foreground. In this way the three are combined organically, each performs its own functions and also interacts with each other, thus can finish system development rapidly.This paper first introduces the structure, technical system and advantages of J2EE, and then explains the component and workflow of Struts, the core interfaces of Hibernate, and the advantage of inversion of control (IoC) and aspect oriented programming (AOP) of Spring. Then analyze the requirements and database design of Iron Laboratory Test Management System, build the develop platform of application system, including framework integration. At last this paper analyzes the function of each module and code implementation in detail. In accordance with the hierarchical principle, this system integrate the three open source framework based on functions, forming a highly efficient and easy-to-use Struts-Spring-Hibernate(SSH) framework. By use of the SSH framework, it reduce the coupling rate of codes, shorten the development cycle, achieve high efficient development, and provide convenient for develop applications.Laboratory management system use SSH as development framework, which facilitating research and application of the system on one hand, and facilitating management and maintenance of the data of the system on the other hand. This system implement the functions of assignment allocation, result enter, examine and verify, query and statistics, role management and code management, achieve the targets that manage the laboratory work efficiently.
