Standard controller implementations for the portlet MVC framework that comes with Spring. Provides both abstract base classes and concrete implementations for often seen use cases.

A `Controller` - as defined in this package - is analogous to a Struts `Action`. Usually `Controllers` are JavaBeans to allow easy configuration using the {@link org.springframework.beans org.springframework.beans} package. Controllers define the `C` from so-called MVC paradigm and can be used in conjunction with the {@link org.springframework.web.portlet.ModelAndView ModelAndView} to achieve interactive applications. The view might be represented by a HTML interface, but, because of model and the controller being completely independent of the view, PDF views are possible, as well as for instance Excel views.

Especially useful to read, while getting into the Spring MVC framework are the following:

- Controller
- BaseCommandController
- ParameterizableViewController
