Design And Implementation Of Online Banking E-sale System Based On J2EE

The emergence of the Internet has brought obvious convenience to people’s ordinary life. In addition, the emergence of e-commerce has expanded the trading range of goods and services, reduced the transaction time and cost. In order to support the development of vehicles-sale online, the China Construction Bank cooperates with the trading platform, the third-party payment platform and supply chain management platform to provide the online “e-sale” system.The traditional system platforms are based on B/S mode. Although it is easy to maintain the management of this mode, the stability of it is hard to ensure. Considering the integrality for the whole system, we cannot abandon the WEB assets, it is very important to build a safe and efficient "e-sale" online car trading system.According to the design goals and functional requirements of online banking "e-sale" system, the MVC pattern and J2 EE technology are adopted to in the objected system instead of traditional B/S mode. This paper also discussed the architecture of J2 EE, the core technology and SSH(Struts+Spring+Hibernate) framework for in-depth analysis and research. To ensure the security of data transmission, the system used VPN technology-based security and AES encryption strategies. The system also provide monitoring to dynamically maintain the stability of the operating environment, the security for the data storage systems, and and various software products and trading interface transactions outside the system. In order to make sure the stability the safety of the system, multiple parallel servers and backup server are used in this project. After a variety of system testing, the online banking "e-sale" system meets the functional requirements, and of course it will bring great economic and social benefits.
