在经典的J2EE四层体系结构的基础上增加数据持久层,提出了基于J2EE五层体系结构的Web开发
框架 分析了基于Struts框架的J2EE架构中实现对象持久性的局限性,从中分离出对象持久层,并将Hibernate
这个面向对象的轻量级对象持久性技术集成到该架构中 应用DAO设计模式在业务逻辑层与持久层之间设计
了多源数据访问组件,抽象和封装了对不同数据源的数据访问操作,实现对不同类型、结构、环境、用法的异构数
据库的统一访问。-In the classical architecture of J2EE on the basis of four increase in data persistence layer, proposed five-story based on J2EE Web development fr a mework architecture of Struts fr a mework based on J2EE architecture to achieve the limitations of object persistence, object isolated from persistence layer, and the object-oriented lightweight Hibernate object persistence technology integration into the architecture application logic layer and the DAO design pattern in the persistence layer design between the multi-source data access components, the abstract and encapsulate different data sources on the data access operations, to achieve different types, structure, environment, usage, uniform access to heterogeneous databases.
