Design Of Secure E_acution System Based On JavaEE Lightweight Framework

The rapid development of electronic commerce, application has become more andmore complicated based on web development, the development cycle has become longerand longer, it is how to develop rapidly web application with stronger retractility, betterextensibility, higher reusability and easier maintenance that has become the focus ofattention of the developers. Electronic auction is electronic commerce trade activity on theInternet, there existed many unsafe factors in transaction process. Network economy is theeconomy form based on the Internet and electronic commerce as the main body, electronicauction is the important of driving force function to promote the network economydevelopment.Security electronic auction system is designed the following several aspects in thisthesis:(1) Introduced electronic auction’s development, relevant terms and characteristics.(2) Introduced development process of cryptography, researched data encryptiondecryption principle and crypto-algorithm; introduced digital signature, analysed the basicprinciple and function of digital signature, researched algorithm of digital signature,focused on RSA algorithm encryption decryption principle and proof process, realizedRSA algorithm with Java, analysed digital signature technology in Java applicatioins.(3) Analysed the traditional JavaEE framework had defects in enterprise applicationdevelopment, proposed that lightweight framework based on JavaEE to make up somedeficiencies, analysed comprehensively core mechanism of lightweight framework Struts2Spring Hibernate, proposed that integration process based on lightweight frameworkStruts2Spring and Hibernate in indicated layer, business logic layer and persistent layer.(4) Analysed electronic auction system function and framework.(5) Developed security electronic auction system based on JavaEE lightweightframework Struts2Spring Hibernate and the digital signature technology, introduced theprocess of realization in indicated layer, business logic layer and persistent layer by theexample of processing bidding module, provided the main interface diagram about theoperation of the system.
