基于数据持久层的iBATIS DAO研究与应用

Research & Application of iBTIS DAO Based on Persistence Layer

iBATIS Dao模式结合数据持久层方法可以使程序在开发过程中业务逻辑更加清晰,更富于形象性和描述性,使系统有一个相对独立的逻辑层面。文章介绍了iBATIS Dao框架组件的组成,通过一个实例描述了iBA-TIS DAO的具体实现方法,体现了J2EE特有的可伸缩性和可扩展性。

The iBATIS Dao mode using data persistent method makes operation logic in the development of program clearer, more vivid, easier to describe the features. And it helps the system to have a comparative independent logic layer. Firstly, this paper introduces the composing of iBATIS Dao framework components, then describes the iBATIS Dao concrete realization method by citing an example. This example embodies the retractility and expansibility of J2EE.
