摘要： 提出了一种基于元数据的对象管理的Web框架(OMF),OMF针对目前流行的Web框架(如Struts等)缺少存储、一致性差等问题,充分运用JDO、Servlet、JSP等标准,使用XML定义对象元数据,辅以面向域的代码生成技术,实现了对象的持久、事务、表现视图等的一致性管理,并同时集成了灵活的基于角色和ACL的访问控制机制。通过该框架,能实现快速创建Web应用系统,极大地提高开发效率。

Abstract: A metadata-based object management Web framework(OMF) is proposed. Aiming at solving the problems of currently-popular Web frameworks which contain lack of data access layer and bad consistency, OMF implements consistent management of object persistence,transaction and presentation by using the specifications of JDO,Servlet,JSP and the technology of domain-oriented code generation. Access control based on role and ACL is integrated in OMF. The development efficiency of Web application system will be greatly increased by using the framework.
