摘要：

提出一种基于Hibernate的数据访问框架，对其扩展点进行分类和设计研究，根据每类扩展点的特点，给出其设计策略及实现方法。结合实例对每类扩展点的具体实现进行阐述。实验结果表明，该方法能灵活应对数据层上的需求变化，为其他层框架扩展点的研究提供依据。

Abstract:

A Hibernate-based data access framework is presented. The classification and design are done to hot spots. According to different characteristics, different design strategies and methods to realize the hot spots are given. The realization of the hot spots with an example is detailed. The methods provide a good support to the demand changes in data layer, as well as give a reference to the study of hot spots for the frameworks of other layers.

Key words: software framework, hot spot, data layer, design pattern
