Dependency Injection www.edureka.co/spring-framework Central to the Spring Framework is Inversion of Control (IoC) Provides consistent means of configuring and managing business objects Objects created by the container are also called managed objects or beans The container can be configured by XML or Java Annotations
- 10. Model-View-Controller (MVC) Architecture Model-View-Controller architecture is used for interactive web-applications. This model minimizes the coupling between business logic and data presentation to web user. This model divides the web based application into three layers: » Model: Model domain contains the business logics and functions that manipulate the business data. It provides updated information to view domain and also gives response to a query. And the controller can access the functionality which is encapsulated in the model » View: View is responsible for presentation aspect of application according to the model data and also responsible to forward query response to the controller » Controller: Controller accepts and intercepts user requests and controls the business objects to fulfil these requests. An application has one controller for related functionality. Controller can also be depends on the type of clients www.edureka.co/spring-framework
