摘　　要：为解决模型驱动体系结构(MDA)中PSM模型描述存在的问题,以软件体系结构为基础,综合当前J2EE平台下广泛使用的多种应用框架,提取其共同特征并加以抽象分析,建立了一种包括领域构件模型、行为构件模型和界面展示构件模型3部分的J2EE平台模型描述方法。用该方法描述的模型不仅具有J2EE平台的特性信息,还便于向多种目标框架下的代码进行转换。以此为基础,引入抽象平台有关模型和具体平台有关模型的概念,进一步扩展了MDA开发框架。介绍了相应代码生成器的框架设计和实现过程。In order to resolve problems in describing platform specific models of MDA, an architecture based modeling approach for J2EE platform specific models is proposed by analyzing and abstracting the common features of the widely-used Web application frameworks on J2EE. Application model built with this approach is composed of three parts： domain component model, action component model and UI presentation component model, which can be transformed into target codes based on many frameworks easily, while containing the specific information on J2EE platform. Based on this approach, the MDA-based development framework is extended by adding abstract platform specific model and concrete platform specific model. The corresponding code-generator＇s framework and its realization process are presented briefly.
