The Application Research And Implementation Of Logistics Information System Based On J2EE Technology

As one of modern service industries,logistics plays a more and more predominant role in national economy and social development. Logistics informatization has become the key factor and primary problem promoting the growth of logistics industry.This paper analyzes and researches how to build logistics information system,which leads the design and implementation of a logistics information system based on J2EE technology.Firstly,this paper analyzes the goal of a logistics information system according to the feature of logistics information. The whole function structure is designed based on the business analysis.Secondly, this paper researches J2EE core technologh and design patterns. Using a multitiered application model,the system is divided into three tiers,which are presentation tier,business tier and persistence tier. Then some design patterns are applied in these tiers,such as Incepting Filter Pattern,Front Controller Pattern,Command Pattern,Data Access Object Pattern etc. Hibernate technology is used in Persistence tier which makes it easier to access and opreate database. Such a system is flexible,reusable and coupled loosely between the tiers.Then,a Logistics information system is implemented applying the framework. This paper explicates the implementation method of design patterns in each tier and the application of Hibernate technology. The implementation of view tier and access control is included in this paper.Finally,this paper analyzes the procedural model,organization model and information model,then the system design,database design and main operation processing design of the workflow system in logistics information system are produced. Then an actual example is included to illustrate the method whcih integrates the logistics information system with workflow system.
