All Implemented Interfaces:

ApplicationContextAware, ViewResolver

public class ResourceBundleViewResolver

extends AbstractCachingViewResolver

Implementation of ViewResolver that uses bean definitions in a ResourceBundle, specified by the bundle basename. The bundle is typically defined in a properties file, located in the classpath.

This ViewResolver supports internationalization, using the default support of java.util.PropertyResourceBundle.

Extends AbstractCachingViewResolver for decent performance.

Method Detail

setBasename

public void setBasename(java.lang.String basename)

Set the basename, as defined in the java.util.ResourceBundle documentation. ResourceBundle supports different suffixes. For example, a base name of "views" might map to ResourceBundle files "views", "views_en_au" and "views_de".

The default is "views".

Parameters:

basename - the ResourceBundle base name

ResourceBundle

setDefaultParentView

public void setDefaultParentView(java.lang.String defaultParentView)

Set the default parent for views defined in the ResourceBundle. This avoids repeated "yyy1.parent=xxx", "yyy2.parent=xxx" definitions in the bundle, especially if all defined views share the same parent. The parent will typically define the view class and common attributes. Concrete views might simply consist of an URL definition then: a la "yyy1.url=/my.jsp", "yyy2.url=/your.jsp".

Parameters:

defaultParentView - the default parent view

loadView

protected View loadView(java.lang.String viewName,
                        java.util.Locale locale)
                 throws javax.servlet.ServletException

Description copied from class: AbstractCachingViewResolver

Subclasses must implement this method. There need be no concern for efficiency, as this class will cache views. Not all subclasses may support internationalization: A subclass that doesn't can ignore the locale parameter.

Overrides:

loadView in class AbstractCachingViewResolver

Following copied from class: com.interface21.web.servlet.view.AbstractCachingViewResolver

Parameters:

viewName - name of the view to retrieve

locale - Locale to retrieve the view for

Returns:

the View if it can be resolved, or null

Throws:

javax.servlet.ServletException - if there is an error trying to resolve the view

initFactory

protected BeanFactory initFactory(java.util.Locale locale)
                           throws java.util.MissingResourceException,
                                  BeansException

Initialize the BeanFactory from the ResourceBundle, for the given locale. Synchronized because of access by parallel threads.
