WEB Development And Application Based On Light Weight J2EE Architecture

The subject called "Web Development and Application Based on Lightweight J2EE Architecture" comes from the Project of Wuhan Duoluokou Super Market Office Automation System. It is based on the WEB platform, uses the Lightweight Architecture System to improve the user interaction, the security and further enhances the system practicality and the office efficiency.J2EE platform is nearly mature, and has many advantages, such as the higher reliability, the cross-platform portability, the availability of the open-source code and so on. Then, more and more developers use the WEB framework based on J2EE. However the results produced by the solution of J2EE architecture as the core of the traditional EJB architecture are often unsatisfied because of the more complicated programs, the difficulty to test, and the cost of the development and maintenance. Therefore, how to construct the WEB application system, which not only responds to a large number of client users but also enables the system to run safely and stably, meanwhile has the powerful functions, flexible application and the agile development; is one of the hot spots in the technology development of Internet at present. Then, how to select the framework technology suitable for the demands of the application, how to assemble them loosely and how to do some proper extensions to form the lightweight general architecture of the WEB application with J2EE standard but not as the core of EJB, have become very significant.The main work of the thesis is as following:(1) The thesis first researches the basic knowledge of J2EE, analyzes the hierarchical structure of J2EE, and studies the several architecture of the current WEB application and compares the advantages and disadvantages of the lightweight framework with the EJB framework, and analyzes how to construct the architecture of the lightweight framework and introduces the core knowledge on MVC, Struts, Hibernate, Spring and so on.(2) According to the WEB development application, the thesis discusses the lightweight architecture system. And for the WEB development and application based on the lightweight J2EE architecture and the current trend of the J2EE architecture development, the thesis analyzes the lightweight realization and compares with WEB models based on J2EE.(3) The outline design on Wuhan Duoluokou Super Market Office Automation System is introduced.(4) The main interface on Wuhan Duoluokou Super Market Office Automation System is introduced.(5) According to the authors main work in the Office Automation System, the thesis then analyzes and discusses the J2EE lightweight development architecture that is as the core of Spring framework and integrates the persistent framework of Hibernate, and introduces how to design and realize the presentation layer, the business logic layer and the data persistence layer based on this framework by adding new users to the database in the project as an example.
