public class ResourceBundleThemeSource extends Object implements HierarchicalThemeSource, org.springframework.beans.factory.BeanClassLoaderAware
ThemeSource implementation that looks up an individual
ResourceBundle per theme. The theme name gets
interpreted as ResourceBundle basename, supporting a common
basename prefix for all themes.setBasenamePrefix(java.lang.String),

protected MessageSource |
createMessageSource(String basename)
Create a MessageSource for the given basename,
to be used as MessageSource for the corresponding theme.
|
ThemeSource |
getParentThemeSource()
Return the parent of this ThemeSource, or
null if none. |
Theme |
getTheme(String themeName)
This implementation returns a SimpleTheme instance, holding a
ResourceBundle-based MessageSource whose basename corresponds to
the given theme name (prefixed by the configured "basenamePrefix").
|
protected void |
initParent(Theme theme)
Initialize the MessageSource of the given theme with the
one from the corresponding parent of this ThemeSource.
|
void |
setBasenamePrefix(String basenamePrefix)
Set the prefix that gets applied to the ResourceBundle basenames,
i.e.

setDefaultEncoding(String defaultEncoding)
Set the default charset to use for parsing resource bundle files.
|
void |
setFallbackToSystemLocale(boolean fallbackToSystemLocale)
Set whether to fall back to the system Locale if no files for a
specific Locale have been found.
|
void |
setParentThemeSource(ThemeSource parent)
Set the parent that will be used to try to resolve theme messages
that this object can't resolve.

Note that ResourceBundle names are effectively classpath locations: As a
consequence, the JDK's standard ResourceBundle treats dots as package separators.
This means that "test.theme" is effectively equivalent to "test/theme",
just like it is for programmatic java.util.ResourceBundle usage.
ResourceBundle.getBundle(String)public void setDefaultEncoding(String defaultEncoding)
ResourceBundleMessageSource's default is the
java.util.ResourceBundle default encoding: ISO-8859-1.
AbstractResourceBasedMessageSource.setDefaultEncoding(java.lang.String)public void setFallbackToSystemLocale(boolean fallbackToSystemLocale)
ResourceBundleMessageSource's default is "true".

SimpleTheme instances are cached per theme name. Use a reloadable MessageSource if themes should reflect changes to the underlying files.

Note that, by convention, a ThemeSource should at least be able to
return a default Theme for the default theme name "theme" but may also
return default Themes for other theme names.setBasenamePrefix(java.lang.String),
createMessageSource(java.lang.String)protected MessageSource createMessageSource(String basename)
Default implementation creates a ResourceBundleMessageSource. for the given basename. A subclass could create a specifically configured ReloadableResourceBundleMessageSource, for example.
