Method Detail

requiredViewClass

protected Class<?> requiredViewClass()

Description copied from class: UrlBasedViewResolver

Return the required type of view for this resolver. This implementation returns AbstractUrlBasedView.

Overrides:

requiredViewClass in class UrlBasedViewResolver

See Also:

AbstractUrlBasedView

setSourceKey

public void setSourceKey(String sourceKey)

Set the name of the model attribute that represents the XSLT Source. If not specified, the model map will be searched for a matching value type.

The following source types are supported out of the box: Source, Document, Node, Reader, InputStream and Resource.

setUriResolver

public void setUriResolver(URIResolver uriResolver)

Set the URIResolver used in the transform.

The URIResolver handles calls to the XSLT document() function.

setErrorListener

public void setErrorListener(ErrorListener errorListener)

Set an implementation of the ErrorListener interface for custom handling of transformation errors and warnings.

If not set, a default SimpleTransformErrorListener is used that simply logs warnings using the logger instance of the view class, and rethrows errors to discontinue the XML transformation.

See Also:

SimpleTransformErrorListener

setIndent

public void setIndent(boolean indent)

Set whether the XSLT transformer may add additional whitespace when outputting the result tree.

Default is true (on); set this to false (off) to not specify an "indent" key, leaving the choice up to the stylesheet.

See Also:

OutputKeys.INDENT

setOutputProperties

public void setOutputProperties(Properties outputProperties)

Set arbitrary transformer output properties to be applied to the stylesheet.

Any values specified here will override defaults that this view sets programmatically.

See Also:

Transformer.setOutputProperty(java.lang.String, java.lang.String)

setCacheTemplates

public void setCacheTemplates(boolean cacheTemplates)

Turn on/off the caching of the XSLT templates.

The default value is "true". Only set this to "false" in development, where caching does not seriously impact performance.

buildView

protected AbstractUrlBasedView buildView(String viewName)
                                  throws Exception

Description copied from class: UrlBasedViewResolver

Creates a new View instance of the specified view class and configures it. Does not perform any lookup for pre-defined View instances.

Spring lifecycle methods as defined by the bean container do not have to be called here; those will be applied by the loadView method after this method returns.

Subclasses will typically call super.buildView(viewName) first, before setting further properties themselves. loadView will then apply Spring lifecycle methods at the end of this process.

Overrides:

buildView in class UrlBasedViewResolver

Parameters:

viewName - the name of the view to build

Returns:

the View instance

Throws:

Exception - if the view couldn't be resolved

UrlBasedViewResolver.loadView(String, java.util.Locale)
