java.lang.Object org.springframework.context.support.ApplicationObjectSupport org.springframework.web.context.support.WebApplicationObjectSupport org.springframework.web.servlet.view.BeanNameViewResolver
public class BeanNameViewResolver
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.

Ordered
Normally starting with 0 or 1, with Ordered.LOWEST_PRECEDENCE
indicating greatest. Same order values will result in arbitrary
positions for the affected objects.
Higher value can be interpreted as lower priority, consequently the first object has highest priority (somewhat analogous to Servlet "load-on-startup" values).
Note that order values below 0 are reserved for framework purposes. Application-specified values should always be 0 or greater, with only framework components (internal or third-party) supposed to use lower values.
Ordered.LOWEST_PRECEDENCE
public View resolveViewName(String viewName, Locale locale) throws BeansException
ViewResolver
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).
resolveViewName
in interface ViewResolver
viewName
- name of the view to resolvelocale
- Locale in which to resolve the view.
ViewResolvers that support internationalization should respect this.
null
if not found
(optional, to allow for ViewResolver chaining)
