Design And Research Of The Management System Of The Bar Code Based On J2EE FrameWork

In recent years, along with the development of the Internet Technique and business enterprise information-based construction, constructs based on the Web application system demand more and more complex, the development cycle is more and more urgent, meanwhile to the system stability, extended and the maintainable request is also more and more high. In order to improve the efficiency of development, simultaneously consider the application system the flexibility, the security and the usability, needs to have one kind of good design pattern, a good reusable framework of the system design as a feasible option to resolve this urgent problem.Based on the framework of multi-core technology for detailed analysis, apply to Hubei province bar coding management information system development process, through to system demand analysis description, have establish the system level model, and divides the system into the corresponding three levels.Struts is based on the MVC design pattern development framework. System development in Struts Application, has realize the expression tier and the service logic tier separation, when modify the expression tier, can not affect the expression level the realization situation, improve the efficiency of the development system.Spring is comprehensive, the modular frame, separated system structure. Developers can choose any part which uses it separated. Spring frame organized the object in the system effectively, eliminated the module object foundation and use coupling closed question. While eliminating the use of a variety of formats customized document attributes needed .Throughout the application and project, may carry on the configuration through one consistent method.Hibernate takes face the Java environment object/relational database mapping tool, not only manages the mapping database tables category, also provides the data inquiry and data acquisition methods. Hibernate provides the ORM mechanism may map to more than one database table, achieve a variety of entities associated mapping, achieve inheritance mapping. Hibernate provides inquiry language of HQL, has realized the many condition connections inquiry and the dynamic inquiry.This paper presents the Struts + Spring + Hibernate framework to achieve J2EE multi-tier structure, use of open source technology framework, the whole software model layer is clear, structure reasonable, develop a clear division of work and focus, project management simple and short development cycle, easy maintenance. The system characteristic is the current advanced design, the front technology and the outstanding development kit, get developed flexible, low coupling and easy maintenance of Web information systems solutions. Application system also has the certain model function to guide other based on J2EE Web platform, demonstrate the using of this new technology in the development and maintenance of the enterprise convenient and efficient. Find out a framework for the development of enterprise-level applications of a general pattern.
