针对电子口岸系统的特点和技术特殊性,设计了一种基于J2EE多层结构的总体应用架构,多层主要指界面表现层、业务逻辑层和数据访问层,并对每一层都给出了适合于口岸特点的成熟的主流软件技术解决方案及其相应的设计模式,最后举例说明了各层之间的具体配合与程序实现过程。
According to the technical specialty of E-port system, this paper designs a mulfilayer application framework based on J2EE. Muhilayer mainly includes the interface manifest layer, the business logic& layer and the data visiting layer. This article also presents well-rounded soft technique and design pattern in every layer, which is mostly fitted for the specialty of E-port system, and finally gives an example to illustrate the cooperation in each layer and the realizing process with procedure.
