【摘要】 随着移动通信市场的日益扩大和新技术手段的不断涌现,用户对移动通信的需求己从基本的语音通信逐步拓展为对移动增值业务的全面需求。随着网络技术的发展,web应用软件己成为各类大型开发项目的首要选择。而当前Web应用软件的开发并没有一种成熟、快速的开发架构和解决方案。本文所做的工作就是对这种架构和解决方案的探索和研究。论文依据因特网的实际应用情况,构建了基于J2EE架构的中国联通网络销售业务平台。中国联通网上营业厅是基于目前联通业务销售的创新产品,该产品以联通广大的手机用户为销售目标群体,以网络销售为渠道,提高业务收入和利润,形成和竞争对手的差别优势,是联通开展数据业务的有效手段,是总部整合营销的有利模式。中国联通网上营业厅系统具有用户数量大、处理数据量大、并发性强、业务逻辑复杂等特点,同时要求系统能够满足未来业务需要的变化,易于扩展、升级和维护。本文的研究成果是:分析和研究了多层分布式架构、J2EE标准规范,提出了一种运用J2EE标准规范开发企业级应用系统的技术方案。并运用该技术方案实现了一个网络营业厅系统,在系统设计过程中:1.对网上营业厅系统架构进行了设计,将系统划分为数据服务层、业务逻辑层和表现层,使系统具备良好的可扩展性、可维护性。2.对网上营业厅系统的安全体系做了设计,将安全体系划分为安全目标,安全保障,安全防护等。3.网上营业厅各种流程进行了详细设计,主要涉及了用户登入、登出及sso。通过中国联通网上营业厅系统的实现,对应用J2EE标准规范实现企业级应用系统的可行性做出了分析,为大型企业级应用系统在J2EE平台的实现打下了基础。更多还原

【Abstract】 Along with the gradual expansion of mobile telecommunication market and the continuous appearances of new technology, users’ requirement for mobile telecommunication has been enlarged from audio communication to the entire demand of mobile value-added business. With the development of network technology and our country legal promotion of process, Web application has already become a first choice of all kinds of large-scale projects. But today when we develop software of Web application, we will find there is no mature quick development framework and solution. In this article we attempt to research a kind of framework and solution.According to the practical application of internet, this thesis instructing on-line Business hall system as sale platform of China Unicom which is based on the structure of J2EE. on-line Business hall system for China Unicom is the innovative product based on business sale of China Unicom, this product targets the group of customers at mobile users of China Unicom, it keeps the way of internet sale, and boost up the business incoming and profits. and it takes the advantageous position in the competition with opponents. It is the effective method for China Unicom to perform data business and it is also the advantageous mode for headquarter to merge its business.On-line Business hall system for China Unicom system has large quantity of users, great capacity of data processing, complicated business logic, strong concurrence, and should be easily updated, expanded and maintained. To raise the efficiency of system development, we should pay much attention to system architecture, technology and design pattern. The achievements of this thesis:In this paper, through the analyzes to multi-tiered distributed architecture, , we propose a scheme for developing enterprise application system with J2EE technology, and develop a system for on-line Business hall system. During the process of system development: 1. Design of the business system architecture, including presentation tier, business logic tier and data services tier, which ensures the application system can be easily updated, expanded and maintained.2. Design of the business system safe architecture, including Security objectives、system security、protection of system.3. Detailed design of the various processes of the on-line business system, including users login/out and sso.Through the Business hall system for China Unicom system development, we evaluate the possibility of developing enterprise application system with J2EE, and make a conclusion that J2EE is an effective measure to develop enterprise application system.更多还原
