基于Java平台的通用构件库的研究与设计

为提高软件的复用程度，采用了基于领域工程的开发方法，提出了领域信息系统设计体系结构和软件构架．重点讨论了领域信息系统模型结构和通用构件库的设计，初步实现了通用构件库中对构件的标识、验证和分类功能，并在组件模型JavaBeans支持下，实现了构件库分析过程的UML描述。通用构件库具有类继承度高、类耦合度低、类封装性高、类多态性低、构件的方法重用效率和类重用效率均比较高等特点并为快速重构应用系统提供了技术上的保证。

Research and implementation on general component library based on java

In order to promote the reuse ability of software, the domain engineering-based development method is used. A design architecture and software architecture in domain information system are presented. Model architecture of domain information system and the design of the general component library is emphasized. The system implements a general component library to mark, inspect, classify and administrate components. Supported by the JavaBeans, analysis process of component library in UML is described. The general component library is high in class inheritance, low in class coupling, high in class sealing, low in class diversifying, high in efficiency of method reuse and efficiency of class reuse. Technical ensure to quickly reconstruct application system is provided.
