public class BeanNameViewResolver extends WebApplicationObjectSupport implements ViewResolver, Ordered
A simple implementation ofViewResolver
that interprets a view name as a bean name in the current application context, i.e. typically in the XML file of the executingDispatcherServlet
.This resolver can be handy for small applications, keeping all definitions ranging from controllers to views in the same place. For larger applications,
XmlViewResolver
will be the better choice, as it separates the XML view bean definitions into a dedicated views file.Note: Neither this
ViewResolver
norXmlViewResolver
supports internationalization. ConsiderResourceBundleViewResolver
if you need to apply different view resources per locale.Note: This
ViewResolver
implements theOrdered
interface in order to allow for flexible participation inViewResolver
chaining. For example, some special views could be defined via thisViewResolver
(giving it 0 as "order" value), while all remaining views could be resolved by aUrlBasedViewResolver

BeanNameViewResolver
public BeanNameViewResolver()
Method Detail
setOrder
public void setOrder(int order)
Specify the order value for this ViewResolver bean.The default value is
Ordered.LOWEST_PRECEDENCE
, meaning non-ordered.- See Also:
Ordered.getOrder()
getOrder
public int getOrder()
Description copied from interface:Ordered
Get the order value of this object.Higher values are interpreted as lower priority. As a consequence, the object with the lowest value has the highest priority (somewhat analogous to Servlet
load-on-startup
values).Same order values will result in arbitrary sort positions for the affected objects.
- Specified by:
getOrder
in interfaceOrdered
- Returns:
- the order value

resolveViewName
@Nullable public View resolveViewName(String viewName, Locale locale) throws BeansException
Description copied from interface:ViewResolver
Resolve the given view by name.Note: To allow for ViewResolver chaining, a ViewResolver should return
null
if a view with the given name is not defined in it. However, this is not required: Some ViewResolvers will always attempt to build View objects with the given name, unable to returnnull
(rather throwing an exception when View creation failed).- Specified by:
resolveViewName
in interfaceViewResolver
- Parameters:
viewName
- name of the view to resolvelocale
- the Locale in which to resolve the view. ViewResolvers that support internationalization should respect this.- Returns:
- the View object, or
null
if not found (optional, to allow for ViewResolver chaining) - Throws:
BeansException
