Document Transmission System Design And Implement Based On Java EE Framework

To meet the need of document transmission among enterprises and public institutions, the document transmission system was developed to realize the document network transmission, receipt, print and other functions based on network technology. The essence of the system is to maintain security, validity, legality and other characteristic of documents. Platform architecture is a system prerequisite for document transmission with high efficiency. It's vital to apply Java EE framework technology and design patterns to the system. At the same time, how to encrypt data and decrypt data to guarantee the security of document transmission during the system building process is not only the key problem to be solved, but also the core of this paper.Taking"learning theory research, system model architecture, method application and optimization"as the storyline, this thesis had done some work on research and design of system architecture and data security. Firstly, this thesis proposed design goals and design principles according to the actual needs of document transmission, Java EE Framework Technology and MVC design patterns under the institution of theoretical basis and technical practice. It figured out the system architecture and supported frame technology for various hierarchical models according to characteristics of system and actual needs which made the complexity of system structure more reasonable and function of each layer more singular and put the low coupling between system layers and business system into practice. Secondly, this thesis puts forward the e-seal technology to ensure the security of document transmission system. And this technology was applied based on the architecture mentioned before which gives the realization of reliability and safety.Finally, detailed analysis was done as to the security realization of document transmission system as well as the architecture realization of system. At the same time, taking documents registration as example, this paper gives a detailed account of the implementation process for several functional modules. The discussion focused on functions given in this paper may have some contribution to similar applications.
