Class BeanNameViewResolver

java.lang.Object

org.springframework.context.support.ApplicationObjectSupport

org.springframework.web.context.support.WebApplicationObjectSupport

org.springframework.web.servlet.view.BeanNameViewResolver

All Implemented Interfaces:

Aware, ApplicationContextAware, Ordered, ServletContextAware, ViewResolver

public class BeanNameViewResolver
extends WebApplicationObjectSupport
implements ViewResolver, Ordered

A simple implementation of ViewResolver that interprets a view name as a bean name in the current application context, i.e. typically 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 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 nor XmlViewResolver supports internationalization. Consider ResourceBundleViewResolver if you need to apply different view resources per locale.

Note: This ViewResolver implements the Ordered interface in order 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.

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 interface Ordered

Returns:

the order value

resolveViewName

@Nullable
public View resolveViewName(java.lang.String viewName,
                                      java.util.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 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 - 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
