public class InternalResourceViewResolver
extends UrlBasedViewResolver

Convenient subclass of UrlBasedViewResolver that supports InternalResourceView (i.e. Servlets and JSPs) and subclasses such as JstlView and TilesView.

The view class for all views generated by this resolver can be specified via UrlBasedViewResolver.setViewClass(java.lang.Class). See UrlBasedViewResolver's javadoc for details.

BTW, it's good practice to put JSP files that just serve as views under WEB-INF, to hide them from direct access (e.g. via a manually entered URL). Only controllers will be able to access them then.

Note: When chaining ViewResolvers, an InternalResourceViewResolver always needs to be last, as it will attempt to resolve any view name, no matter whether the underlying resource actually exists.

Constructor Detail

InternalResourceViewResolver

public InternalResourceViewResolver()

Sets default viewClass to requiredViewClass.

See Also:

UrlBasedViewResolver.setViewClass(java.lang.Class), requiredViewClass()

Method Detail

requiredViewClass

protected Class requiredViewClass()

Requires InternalResourceView.

Overrides:

requiredViewClass in class UrlBasedViewResolver

See Also:

InternalResourceView

setAlwaysInclude

public void setAlwaysInclude(boolean alwaysInclude)

Specify whether to always include the view rather than forward to it.

Default is "false". Switch this flag on to enforce the use of a Servlet include, even if a forward would be possible.

See Also:

InternalResourceView.setAlwaysInclude(boolean)

buildView

protected AbstractUrlBasedView buildView(String viewName)
                                  throws Exception

Description copied from class: UrlBasedViewResolver

Creates a new View instance of the specified view class and configures it. Does not perform any lookup for pre-defined View instances.

Spring lifecycle methods as defined by the bean container do not have to be called here; those will be applied by the loadView method after this method returns.

Subclasses will typically call super.buildView(viewName) first, before setting further properties themselves. loadView will then apply Spring lifecycle methods at the end of this process.

Overrides:

buildView in class UrlBasedViewResolver

Throws:

Exception
