摘　　要：基于组件的软件工程(CBSE)关注于如何将已有的组件整合为大型的软件系统。传统的软件开发观念已被基于组件的应用系统所取代,采用CBSE可以有效地提高软件的灵活性、适应性和可维护性。许多运行于重要行业的关键系统要求不间断地对外提供服务,因此这类系统的更新升级必须在系统的运行时动态进行。文章首先对动态升级技术的相关概念进行了介绍,然后在对几种动态升级技术研究的基础上提出一种改进的升级方法,最后基于JavaBeans组件模型对该方法进行了实验验证,得出结论。Component-Based Software Engineering focuses on building large software systems by integrating existing software components. The old notion of developing a system by writing code has been replaced by assembling existing components. The main aim of CBSE is to enhance the flexibility and maintainability of systems. Some of these systems are critical, and should not be stopped to be maintained. Such systems must be adapted on the fly. In this paper, we provide a survey of the main concepts of the dynamic updating. The remainder of the paper presents our updating approach experimented on the JavaBeans component model.
