Design And Implementation Of The International Post System Based On J2EE Framework

With the development of network, J2EE platform is adopted more and more extensive in reality systems. Based on Java technology, J2EE is a platform standardization of distributed component computing, which is proposed and formulated by SUN Enterprise. Based on J2EE, the application system with multi-tier structure can be rapidly developed and deployed, which is easy to translatability. The archetype of MVC design pattern is Web N layers system structure of J2EE.During the developing of J2EE enterprise applications, using MVC pattern can make developing structure clear; at the same time, this can effectively improve the performance of the software system. Struts is an excellent application framework to implementing MVC pattern. Hibernate is a kind of resolvent of object/relation mapping. That is to say, makes object-object relational in Java mapping to table-table relation in relational data-base.The system of tracking international posts can query all international evidence posts' states from pack off to mailing. Based on the character of demand; we adopt MVC design pattern based on J2EE frame to realize. We map the whole model flow chart of the system to Struts developing framework of MVC pattern. We encapsulate the query conditions, that is to say, request information to Actionform through jsp/xml view layer module of struts framework. Through config file of controller, we send the data of Actionform to the special model layer module to handle. Finally...
