J2EE构件化软件支撑平台研究与应用开发

为了提高软件复用程度，适应需求变化，提高业务应用系统开发效率和可维护性，研究了构件化、平台化的软件开发方法。基于Java2企业版（J2EE）的软件支撑平台，应用结构化、层次化和面向对象的方法，重点研究了软件支撑平台组成结构、软件构件定义、属性、表现和模型、构件分类与管理技术。同时，结合J2EE构件化软件支撑平台及其构件，研究了基于构件的业务应用软件的开发方法和过程模型。给出了基于J2EE的软件支撑平台的业务应用具体开发步骤，在多个实际项目中得到了应用。应用结果表明，提高了业务系统开发效率20％左右，软件复用显著提高，适应需求变化，可维护性增强。

Component software support platform based on Java2 Enterprise Edition

Some software development methods on platform and component have been researched to improve reused ratio, development efficiency and maintenance of software. The author has studied the architecture of software support platform based on Java2 Enterprise Edition（J2EE）, focusing on the characteristics, definition, behavior, model, classification and management of components, by using hierarchical and object oriented methods. The process model and development method of the business application software are studied based on this support platform and its components, which are applied to some information management systems. The results of applications illustrate that the reused ratio and maintenance of software have been improved greatly, the development efficiency with these methods has increased by 20%, and these software can adapt to requirement changes rapidly.
