public class TilesView
extends AbstractUrlBasedView

View implementation that retrieves a Tiles definition. The "url" property is interpreted as name of a Tiles definition.

This class builds on Tiles2, which requires JSP 2.0. JSTL support is integrated out of the box due to JSTL's inclusion in JSP 2.0. Note: Spring 4.0 requires Tiles 2.2.2.

Depends on a TilesContainer which must be available in the ServletContext. This container is typically set up via a TilesConfigurer bean definition in the application context.

Since:

2.5

Method Detail

setAlwaysInclude

public void setAlwaysInclude(boolean alwaysInclude)

Specify whether to always include the view rather than forward to it.

Default is "false". Switch this flag on to enforce the use of a Servlet include, even if a forward would be possible.

Since:

4.1.2

See Also:

TilesViewResolver.setAlwaysInclude(java.lang.Boolean)

checkResource

public boolean checkResource(Locale locale)
                      throws Exception

Description copied from class: AbstractUrlBasedView

Check whether the underlying resource that the configured URL points to actually exists.

Overrides:

checkResource in class AbstractUrlBasedView

Parameters:

locale - the desired Locale that we're looking for

Returns:

true if the resource exists (or is assumed to exist); false if we know that it does not exist

Throws:

Exception - if the resource exists but is invalid (e.g. could not be parsed)

renderMergedOutputModel

protected void renderMergedOutputModel(Map<String,Object> model,
                                       HttpServletRequest request,
                                       HttpServletResponse response)
                                throws Exception

Description copied from class: AbstractView

Subclasses must implement this method to actually render the view.

The first step will be preparing the request: In the JSP case, this would mean setting model objects as request attributes. The second step will be the actual rendering of the view, for example including the JSP via a RequestDispatcher.

Specified by:

renderMergedOutputModel in class AbstractView

Parameters:

model - combined output Map (never null), with dynamic values taking precedence over static attributes

request - current HTTP request

response - current HTTP response

Throws:

Exception - if rendering failed
