n a previous article, I introduced you to the Spring framework, showed you how to use Spring's basic functionality to create objects, and how to do some simple database interactions. In this follow-up article I will introduce you to the Spring model-view- controller (MVC) framework by walking you through the creation of a simple stock-trading Web application.
MVC is a pattern that helps separate presentation from business logic. In short, in an MVC application all Web requests are handled by controllers. A "controller" is responsible for interpreting the user's request and interacting with the application's business objects in order to fulfill the request. These business objects are represented as the "model" part of the MVC. Based on the outcome of the request execution, the controller decides which "view" to forward the model to. The view uses the data in the model to create the presentation that is returned to the user.
