The Design And Implementation Of Postal 11185 Business System Based On J2EE

Frameworks and design patterns are very important technologies for software which are reused in J2EE. With using framework, productivity of software can be raised. Almost all frameworks use one or more design patterns. For designers and developers, it is a challenge that how to choose frameworks to build the appropriate architecture for enterprise application and how to make each application layer interact in loose coupling way.Based on comparison of various technologies and in order to meet the needs of Postal 11185 business system, this paper chooses the Struts and Hibernate framework. Using these frameworks, this paper designs and implements parts of functional modules.Firstly, this paper investigates and researches the popular framework and theoretical of MVC design pattern. And further, this paper analyzes and compares the mainstream framework technology. Secondly according to the Platform Concepts and Open-Closed Principle, this paper designs the overall system based on the analysis of the project, including system architecture, system structure, system security and database. Finally this paper discusses the design and implementation of specific modules that the author participates in, and deeply discusses the related technologies used in these modules.Through the application of these open-source frameworks development time and costs have been saved, and it improves the work efficiency.
