基于J2EE的对外加工贸易企业物料监管系统的研究与设计
|
摘要
在充分研究对外加工贸易企业特点、需求,海关监管的各种工作流程和业务标准,以及对现有物料管理系统进行分析的基础之上,结合目前比较流行的J2EE技术,提出了一种基于J2EE的对外加工贸易企业物料监管系统。通过对系统各模块的设计与实现,以及对难点问题的解决方法的分析,最终实现了基于多层结构的管理系统。本系统实际运行后,达到了预期效果。
系统使用MVC设计模式来对系统进行分析设计,从而实现了以面向对象的方法来对系统进行分析和设计,使系统的开发变得比较简单和容易理解。对于新录入数据的验证,系统采用将实现正则表达式匹配功能的JavaScript脚本嵌入在页面中,在客户端直接运行,这样做既提高了系统响应速度,又减少了服务器的负担和网络的流量;数据库中BOM表的设计,系统采用了单层关系的设计方法,即可让复杂的物料关系变得相对简单,又使表的开发与维护变得比较容易;在系统的安全性方面,采用了基于角色的用户认证和访问控制机制,并结合声明性和编程性两种安全策略,以确保系统自身的安全性。此外,还对如何实现导入原始数据,进行了分析与设计。
系统采用J2EE作为分布式开发平台,实现了逻辑和数据分层处理的多层体系结构,这样不仅提高了系统的稳定性,而且也提高了系统的可扩展性。
This paper proposes a foreign processing trade enterprise material supervising system based on J2EE whose foundation is to fully research on foreign processing trade enterprise characteristic, demand, each kind of work flow, the service standard of the customs supervising and existing material supervising system. The management system based on multilayer structures is realized by designing and realizing each function and database, as well as analyzing solution to difficult questions. The system has been used in practice and received expected results.
The system uses the MVC design pattern to analyze and design, which makes system development simpler and is easy to understand using object-oriented analysis and design. To confirm new input data, JavaScript with the regular expression match function is inserted the page and can be run directly in the client side, which both enhances the speed of response and reduced the server burden and the network current capacity. The single-layer relations design which simples the complex material relations and makes development and the maintenance easier is used to design the BOM table in the database. As system secure, mechanism of user authentication and the access control based on the role is used to ensure system own security, which binds two kind of security strategy, namely statement and programming. Moreover, it how to implement importing original data is analyzed and designed in detail.
The system adopts J2EE as the distributional development platform to realize multilayered system structure of logical and the data lamination processing, which enhances not only system stability but also system extendibility.
