public TilesView()

Method Detail

setRenderer

public void setRenderer(Renderer renderer)

Set the Renderer to use. If not set, by default DefinitionRenderer is used.

setExposeJstlAttributes

protected void setExposeJstlAttributes(boolean exposeJstlAttributes)

Whether to expose JSTL attributes. By default set to true.

See Also:

JstlUtils.exposeLocalizationContext(RequestContext)

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)

afterPropertiesSet

public void afterPropertiesSet()
                        throws java.lang.Exception

Description copied from interface: InitializingBean

Invoked by the containing BeanFactory after it has set all bean properties and satisfied BeanFactoryAware, ApplicationContextAware etc.

This method allows the bean instance to perform validation of its overall configuration and final initialization when all bean properties have been set.

Specified by:

afterPropertiesSet in interface InitializingBean

Overrides:

afterPropertiesSet in class AbstractUrlBasedView

Throws:

java.lang.Exception - in the event of misconfiguration (such as failure to set an essential property) or if initialization fails for any other reason

checkResource

public boolean checkResource(java.util.Locale locale)
                      throws java.lang.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:

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

renderMergedOutputModel

protected void renderMergedOutputModel(java.util.Map<java.lang.String,java.lang.Object> model,
                                       HttpServletRequest request,
                                       HttpServletResponse response)
                                throws java.lang.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:

java.lang.Exception - if rendering failed

createTilesRequest

protected Request createTilesRequest(HttpServletRequest request,
                                     HttpServletResponse response)

Create a Tiles Request.

This implementation creates a ServletRequest.

Parameters:

request - the current request

response - the current response

Returns:

the Tiles request
