Design Of Java Web Framework For Constructing Small Portal Site Rapidly

Portal,the original meaning is access.Now it is usually used in Website on Internet. The portal site is a application framework,it integrats kinds of application system,date source,internet source on a management information system.and provide united user interface,It allows enterprise can build the information channel between enterprise and custom, enterprise and employee,or enterprise and enterprise at a rapi,and make enterprise can release its information inside or outside.small portal site usually has characteristic of simply business,no- distributed and so on.Framework is a particular type of software constitutes a reusable design collaboration between a group of classes.Framework provides the architecture of your application.It defines the overall structure of the division of classes and objects, the primary responsibility for each part, how classes and objects collaborate, and control processes.Pre-defined framework of these design parameters to the application designer or implementer to focus on the details of the application itself.Framework of the record field of its application to design decisions.Thus more emphasis on design reuse framework, although the framework of the immediate applications often include specific sub-category.With the rise of Internet technology, based on B/S structure of Web applications are used more and more areas.Through this article will design a Java Web framework for rapidly building small portal site,which is based on component-based and event-driven, in order to save labor.Through detailed analysis of the mainstream framework of the current market the advantages and disadvantages. By using components within simple interface and the event mechanism design, to make the framework more friendly and easier to use and expand.And aiming at problems which such framework will often face, for example "Event location strategy","Event handle" and "state management" and other issues, propose reasonable solutions.
