摘要
在研究大量流行的Web应用框架的基础上,提出一种Web应用系统权限框架整合模型,该模型基于分层思想,结合设计模式方法,在数据库连接JDBC与Web的应用服务之间增加数据过滤层,给出一组约束,增加域对象层、服务定位层和数据接口层,有效地解决了框架整合过程中出现的功能冗余、层间通信不便、耦合度太高等问题。该模型充分挖掘各个框架的长处,使它们以一种松散耦合方式结合,形成一个更高层次的应用框架,虚拟实现数据库的用户授权模式。
It was given a model of Web application authority control framework composition on the base of research of many popular Web application frameworks. It was based on layer architecture,combines with design pattern, inserted a data filter layer between JDBC and Web application service, given a set of restrictions, and introduced three new layers which were domain object layer, service locator layer and data access interface layer. The model solved the problems such as function redundancy, inconvenience of layer communication and tight coupling in the process nf frameworks composition. The model made full use of strongpoint of each Web application framework, combined them to achieve loose coupling and virtually implementing the authorization schema of database users.
