The sound of firecrackers makes the years taste heavier and the festive atmosphere more real. There are a lot of different kind of fireworks and various setting effects. The fireworks are disposable products, resulting in that they are gone after burning, meanwhile consumers cannot try them before purchase the products, thus consumers buy fireworks only reling on the sales personnel oral presentation. In this case, the consumers can not return purchases if the setting effect is bad, which greatly destories the atmosphere for the Spring Festival. With the gradually increasing of intelligent mobile phone users, twodimensional code is popular in market, which appearring let people get rid of the trouble of the manual input so s to access connection through easily sweepping the twodimensional code. With the fireworks live preview system based on twodimensional code, consumers can preview effect of the fireworks before they buy them only by sweepping the twodimensional code, which can make it possible to buy after get satisfied setting effects, so that the consumers buy the fireworks happily and assured. The system uses B/S architecture based on J2EE, SSH frameworks, the front HTML5 technology, and MySQL database system to realize data storage. The system mainly provides some basic function modules: video preview, product introduction, user evaluation and so on. By sweepping the twodimensional code, consumers can get all relevant details of the fireworks and preview fireworks real setting effects, which make the consumers buy fireworks relieved, meawhile take more benefit for the merchants. Key words: The twodimensional code, HTML5, SSH, Fireworks Live Preview System 基于二維碼的煙花燃放實景預覽系統(tǒng)的設計與實現(xiàn) III 目 錄 摘 要 .......................................................................................................................................
