Method Details

setTemplateEngine

public void setTemplateEngine(groovy.text.markup.MarkupTemplateEngine engine)

Set the MarkupTemplateEngine to use in this view.

If not set, the engine is auto-detected by looking up a single GroovyMarkupConfig bean in the web application context and using it to obtain the configured MarkupTemplateEngine instance.

See Also:

• GroovyMarkupConfig

initApplicationContext

protected void initApplicationContext(ApplicationContext context)

Invoked at startup. If no templateEngine has been manually set, this method looks up a GroovyMarkupConfig bean by type and uses it to obtain the Groovy Markup template engine.

Overrides:

initApplicationContext in class WebApplicationObjectSupport

Parameters:

context - the containing ApplicationContext

See Also:

• GroovyMarkupConfig
• setTemplateEngine(groovy.text.markup.MarkupTemplateEngine)

autodetectMarkupTemplateEngine

protected groovy.text.markup.MarkupTemplateEngine autodetectMarkupTemplateEngine()
                                                                          throws BeansException

Autodetect a MarkupTemplateEngine via the ApplicationContext. Called if a MarkupTemplateEngine has not been manually configured.

Throws:

BeansException

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 (for example, could not be parsed)

renderMergedTemplateModel

protected void renderMergedTemplateModel(Map<String,Object> model,
 jakarta.servlet.http.HttpServletRequest request,
 jakarta.servlet.http.HttpServletResponse response)
                                  throws Exception

Description copied from class: AbstractTemplateView

Subclasses must implement this method to actually render the view.

Specified by:

renderMergedTemplateModel in class AbstractTemplateView

Parameters:

model - combined output Map, with request attributes and session attributes merged into it if required

request - current HTTP request

response - current HTTP response

Throws:

Exception - if rendering failed

getTemplate

protected groovy.text.Template getTemplate(String viewUrl)
                                    throws Exception

Return a template compiled by the configured Groovy Markup template engine for the given view URL.

Throws:

Exception
