The Design And Implementation Of Time Card Based On Taobao Electronic Certificate Trading System

Electronic certificate technology plays an irreplaceable role in the development of 020 which means offline to online. Users purchase online products or services whil e the system send the only electronic certificate to to the user, the user with the cer tificate to offline to consume and enjoy the service. We solve the transaction proce ss of online and offline through this consumption mode.However the reality is often more complex, in actual process, this mode is applic able in most cases, such as restaurants, movie tickets, but in some cases is not suita ble, such as the purchase of a number of cases, electronic document membership car d etc. Based on these scenarios is in need of electronic certificate becomes more flexi ble. From the original generation -- simple life cycle verification into a variety of life cy cle in parallel, such as one code with one consume time, one code with many cons uming times. And the one code with many consuming times developed to time card, aging card as well.Aging card can refer to the electronic certificate of unlimited number for consumin g without failure in the formulation of the time, this kind of electronic certificate similar to the park’s card, there is also an open card time, which the certificate will not take effects immediately after purchasing but the user use certificate for the first time t hat will take effects, but also to ensure the validity of the card can not exceed itsel f. Aging card system belongs to a complex electronic certificate system.Electronic certificate technology of Taobao used J2EE technology, Using WebX t o show the front. Using Spring and Maven to call the other systems’libraries, using ibatis and Mysql as the database and database persistence. The container is imple mented by jBoss, using HSF, Tair and other high performance middleware to suppor thigh concurrent business. The system is using the corresponding technique for func tional iterative development based on the original system.Because the system is at the core of the Taobao trading line system, so the stability of system requirements i svery high, so completely adopts the Taobao’s past frame structure is the way to r ealize a secure.This paper will do from the buyer behavior of placing an order, to payment, refu nd, resend the code, expired automatic verification, prolong the period of validity, mo difying the mobile phone number and a series of processes of aging card function. Ta obao’s electronic certificate system have two set of system,which calls Taobao codes and business codes, This paper will realize the aging card function for the two sys tem respectively. For sellers, aging card item list and modify also need to do the corr esponding function iteration.Through the development of more than a month, finally the system is compelete d. We realized all the basic function. Because the trading system is the core system of Taobao.There is a high requirement for stability.However the system worked wel l for two months online, without any problems.
