public class BeanNameViewResolver
extends org.springframework.web.context.support.WebApplicationObjectSupport
implements ViewResolver, org.springframework.core.Ordered

Simple implementation of ViewResolver that interprets a view name as bean name in the current application context, i.e. in the XML file of the executing DispatcherServlet.

This resolver can be handy for small applications, keeping all definitions ranging from controllers to views in the same place. For normal applications, XmlViewResolver will be the better choice, as it separates the XML view bean definitions into a dedicated views file. View beans should virtually never have references to any other application beans - such a separation will make this clear.

This ViewResolver does not support internationalization. Conside ResourceBundleViewResolver if you need to apply different view resources per locale.

Note: This ViewResolver implements the Ordered interface to allow for flexible participation in ViewResolver chaining. For example, some special views could be defined via this ViewResolver (giving it 0 as "order" value), while all remaining views could be resolved by a UrlBasedViewResolver.

resolveViewName

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 return null (rather throwing an exception when View creation failed).

Specified by:

resolveViewName in interface ViewResolver

Parameters:

viewName - name of the view to resolve

locale - 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:

org.springframework.beans.BeansException
