Java EE数据持久层解决方案的设计与实现

数据持久化是Java EE应用开发过程中一个重要组成部分,也是构建企业级应用系统必须首先面对的重要问题。该文在分析比较现有持久层解决的基础上,根据实际开发的需要,提出了一种以XML作为交互数据格式,增加适当配置文件,实现数据访问与应用逻辑分离,集安全、权限和异常处理机制为一体的通用的持久层解决方案;该方案的具体实施为系统的拓展、移植、重组维护打下了一个良好的基础。

Design and implementation of persistence layer's solutions based on Java EE

Data persistence is an important part of development in Java EE,and it is an intractable problem in the process of designing enterprise application systems.Based on the analysis and comparison of current general solutions and the actual needs of the development,a universal solution is proposed by a combination of the use of XML as the interactive data format,addition of appropriate configuration files,separation of the data access from application logic,and integration of the security,authority and anomaly handling mechanism.The implementation of the resolution lays a good foundation for systematic extension,transplant,and recomposition.
