A Research On OA Domain Reuse Based On Struts Framework

With the development of information technology,the ways of office working gradually have transformed into office automation on the Internet platform.The government departments and enterprises are trying to build their own office automation systems(OA).There is such a problem in this process:with the development of society and the changes of people's ways of dealing with affairs,the requirements and processes of office are changed.Therefore,the existing OA systems often need to be updated to satisfy the new demandsDuring my internship in Yunnan branch of Xinhua News Agency last year,I fully feel the great convenience that OA system brings us.However,advanced and efficient OA system also need to maintain and update constantly.Therefore,considering the design and implementation of the system which is extensible and reusable,rather than starting from writing the general business logic code in the domain of OA.While shortening the development cycle and reducing development costs,the office requirements and the changes of business process can also be dealt with flexibly.This paper,starting from the idea of software reuse,domain-specific framework and component reuse,combined with domain specific software development and based on the Struts framework,studies OA system reuse.Firstly,this paper extends the Struts framework to implement Struts framework reuse;Then,it studies components in the Struts framework and solve the problem of component classification,interface and so on to further implement the component level reuse.Finally,this paper puts forward the document flow modulein OA system based on the reusable components.
