Abstract

Along with the gradual maturity of distributed computing platform J2EE, J2EE has become the current mainstream enterprise application and development platform and J2EE/EJB technology makes system have a good technical foundation on expansibility, portability and flexibility. Against the background of a certain logistics management system development, an analysis and design of MVC design pattern under J2EE architecture is carried out in this paper. On business layer, the entity bean is encapsulated by session bean, which normalizes the client access, reduces the coupling between business layer and client end, centralizes security management and transaction control and improves the performance. Meanwhile, the value object is introduced into the system to encapsulate the interactive data between Web layer and business layer, which decreases the network overhead of the system.
