Package org.springframework.web.servlet.mvc

Standard controller implementations for the servlet MVC framework that comes with Spring.

Description

Interface Summary

Controller	Base Controller interface, representing a component that receives HttpServletRequest and HttpServletResponse instances just like a HttpServlet but is able to participate in an MVC workflow.
LastModified	Supports last-modified HTTP requests to facilitate content caching.

Class Summary

AbstractCommandController	Abstract base class for custom command controllers.
AbstractController	Convenient superclass for controller implementations, using the Template Method design pattern.
AbstractFormController	Form controller that auto-populates a form bean from the request.
AbstractUrlViewController	Abstract base class for Controllers that return a view name based on the request URL.
AbstractWizardFormController	Form controller for typical wizard-style workflows.
BaseCommandController	Controller implementation which creates an object (the command object) on receipt of a request and attempts to populate this object with request parameters.
CancellableFormController	Extension of SimpleFormController that supports "cancellation" of form processing.
HttpRequestHandlerAdapter	Adapter to use the plain HttpRequestHandler interface with the generic DispatcherServlet.
ParameterizableViewController	Trivial controller that always returns a named view.
ServletForwardingController	Spring Controller implementation that forwards to a named servlet, i.e. the "servlet-name" in web.xml rather than a URL path mapping.
ServletWrappingController	Spring Controller implementation that wraps a servlet instance which it manages internally.
SimpleControllerHandlerAdapter	Adapter to use the plain Controller workflow interface with the generic DispatcherServlet.
SimpleFormController	Concrete FormController implementation that provides configurable form and success views, and an onSubmit chain for convenient overriding.
UrlFilenameViewController	Simple Controller implementation that transforms the virtual path of a URL into a view name and returns that view.
WebContentInterceptor	Interceptor that checks and prepares request and response.

Package org.springframework.web.servlet.mvc Description

Standard controller implementations for the servlet 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 org.springframework.beans package. Controllers define the C from so-called MVC paradigm and can be used in conjunction with the 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.

How to actually set up a (web)application using the MVC framework Spring provides is explained in more detail in the MVC-Step-by-Step tutorial, also provided in this package (or have a look here for an online version). The classes contained by this package explain in more detail the actual workflow of some of the abstract and concrete controller and how to extend and fully use their functionality.

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

• Controller
• BaseCommandController
• ParameterizableViewController
