Design And Realization Of Internet Package Express System

This thesis aims at solving the informatization requirements of core business of the express company, elaborates the development process of the internet package express system (abbr. IPES) based on the Java open source framework, and focuses on solving follow problems emphatically: Firstly, through the development based on AppFuse, the thesis provides a technical solution for creating lightweight Java EE project quickly, not only keeping the powerful SSH2, but also promoting the development speed. Secondly, the development process always follows the principle of the TDD (Test Driven Development) and it improves quality of the software. Thirdly, the developments and applications of the IPES not only saves the express company's investment, but also meets the urgent demands of the express company for internet package express business, and it has great value to be widely used in express industrial fields.Firstly, the thesis introduces the system architecture of the lightweight Java EE platform, explains the system structures, core conceptions, basic principles of the three open source framework - Hibernate, Spring, and Struts 2 respectively, all of which compose the typical lightweight Java EE platform, and how to integrate each other.Subsequently, the thesis expatiates on the analysis, design, and implementation process of IPES. In analysis phase, the thesis analyses the demands of the system and the business processes, enumerates the operation steps in each business work, and draws the flow charts. In design phase, it draws the use case diagrams and the sequence diagrams of the major subsystems, designs the database, and summarizes the design methods. In implementation phase, it introduces all development tools for the IPES, relates the AppFuse open source framework on the lightweight Java EE platform, illustrates the establishment step of creating SSH2 project by AppFuse, the project management tool - Maven, and the development mode of AppFuse, then, it elaborates the processes and the methods of programming practice based on AppFuse by developing a function in detail. Finally, the thesis sums up development process and offers the development directions of IPES in the future.
