【摘要】 物流作为现代服务业,在国民经济和社会发展中起着越来越重要的作用。在众多影响物流企业发展的因素中,物流信息化是推动物流企业发展的关键因素。本文就如何建设物流信息系统进行分析和研究,并在此基础上设计和实现了基于J2EE技术的物流信息系统。首先,从物流信息的特点出发,分析了物流信息系统要达到的目标,在对物流管理的业务分析基础上,设计了系统的总体功能结构。其次,研究了J2EE核心技术、设计模式,在此基础上将系统分为表现层、业务层及持久层,分析了各层采用的设计模式,并应用拦截过滤器模式、前端控制器模式、命令模式、工厂模式、数据访问对象等设计了一个基于J2EE技术的信息系统的框架。其中,持久层采用了Hibernate持久化技术,简化了对数据库的访问和操作。这样设计的系统具有更大的可伸缩性、灵活性及可复用性,实现了各个层次间的松耦合。同时,应用该框架实现了物流信息系统,详细介绍了各层次设计模式的实现方法、Hibernate技术的应用,视图层的实现以及权限控制的实现方法。最后,研究了工作流相关技术及理论,在分析物流信息系统中工作流管理的过程模型、组织模型及信息模型的基础上,进行了工作流系统的总体设计、数据库设计及主要操作过程的设计,并针对一个具体的业务流程,讨论了物流信息系统与工作流系统的集成方法。更多还原

【Abstract】 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.更多还原
