In spring framework, the controller part is played by the Dispatcher Servletįig. Controller (C): Controller’s responsibility is to invoke the Models to perform the business logic and then update the view based on the model’s output.Views are usually the JSP templates written with Java Standard Tag Library ( JSTL) View (V): A view is an output representation of the information, such as displaying information or reports to the user either as a text-form or as charts.It is a POJO class which encapsulates the application data given by the controller Model (M): Model’s responsibility is to manage the application’s data, business logic, and the business rules.This pattern divides the application into three components to separate the internal representation of the information from the way it is being presented to the user.
