Research Of Light Framework Based On IoC And AOP

After eight year's development and application, the EJB framework has shown its disadvantages day by day. Meantime, many kinds of light frameworks come forth along with the IoC and AOP techniques'emergence. The Spring framework seems one of the best among them, whose core is the mechanism of IoC and AOP.Previously, author has made the development of the Security Guard Information Management System of Tianjin Public Bureau using Spring framework, and this article hope to make a further research on it. This paper starts with the comparisons and analyses of some current frameworks, trying to find out the advantages and disadvantages of the Spring framework. And then, it research some advanced java techniques related to Spring framework, such as class loader, reflect, dynamic proxy, javabean and so on, which constructs the foundation of Spring framework. Thirdly, this article research Spring framework's source code, analyze the realization of IoC and AOP and show its structure and process in detail by the class diagrams and sequence diagrams in UML. At last, this article try to extend the Spring framework to fit the need of an ever-problem in web application, that is, to show the database tables in the same way.The paper analyzes the realization of IoC and AOP in Spring framework, which is valuable for the enterprise foundation platform application. It also emphasizes Spring frame's value in foundation application by an example of extending Spring framework, which to some extend innovated the IoC and AOP application.
