Aware, BeanClassLoaderAware, HierarchicalThemeSource, ThemeSource
```
public class ResourceBundleThemeSource
extends Object
implements HierarchicalThemeSource, 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.

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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.
`void`	`setBeanClassLoader(ClassLoader beanClassLoader)`	Callback that supplies the bean `class loader` to a bean instance.
`void`	`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.

public ResourceBundleThemeSource()

- Method Detail
  - setParentThemeSource
```
public void setParentThemeSource(ThemeSource parent)
```
    Description copied from interface: HierarchicalThemeSource
    Set the parent that will be used to try to resolve theme messages that this object can't resolve.
    Specified by:
    setParentThemeSource in interface HierarchicalThemeSource
    Parameters:
    parent - the parent ThemeSource that will be used to resolve messages that this object can't resolve. May be null, in which case no further resolution is possible.
  - getParentThemeSource
```
public ThemeSource getParentThemeSource()
```
    Description copied from interface: HierarchicalThemeSource
    Return the parent of this ThemeSource, or null if none.
    Specified by:
    getParentThemeSource in interface HierarchicalThemeSource
  - setBasenamePrefix
```
public void setBasenamePrefix(String basenamePrefix)
```
    Set the prefix that gets applied to the ResourceBundle basenames, i.e. the theme names. E.g.: basenamePrefix="test.", themeName=theme -> basename="test.theme".
    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.
    See Also:
    ResourceBundle.getBundle(String)
  - setDefaultEncoding
```
public void setDefaultEncoding(String defaultEncoding)
```
    Set the default charset to use for parsing resource bundle files.
    ResourceBundleMessageSource's default is the java.util.ResourceBundle default encoding: ISO-8859-1.
    Since:
    4.2
    See Also:
    AbstractResourceBasedMessageSource.setDefaultEncoding(java.lang.String)
  - setFallbackToSystemLocale
```
public void setFallbackToSystemLocale(boolean fallbackToSystemLocale)
```
    Set whether to fall back to the system Locale if no files for a specific Locale have been found.
    ResourceBundleMessageSource's default is "true".
    Since:
    4.2
    See Also:
    AbstractResourceBasedMessageSource.setFallbackToSystemLocale(boolean)
  - setBeanClassLoader
```
public void setBeanClassLoader(ClassLoader beanClassLoader)
```
    Description copied from interface: BeanClassLoaderAware
    Callback that supplies the bean class loader to a bean instance.
    Invoked after the population of normal bean properties but before an initialization callback such as InitializingBean'sInitializingBean.afterPropertiesSet() method or a custom init-method.
    Specified by:
    setBeanClassLoader in interface BeanClassLoaderAware
    Parameters:
    beanClassLoader - the owning class loader; may be null in which case a default ClassLoader must be used, for example the ClassLoader obtained via ClassUtils.getDefaultClassLoader()
  - getTheme
```
public 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").
    SimpleTheme instances are cached per theme name. Use a reloadable MessageSource if themes should reflect changes to the underlying files.
    Specified by:
    getTheme in interface ThemeSource
    Parameters:
    themeName - the name of the theme
    Returns:
    the corresponding Theme, or null if none defined. 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.
    See Also:
    setBasenamePrefix(java.lang.String), createMessageSource(java.lang.String)
  - createMessageSource
```
protected MessageSource createMessageSource(String basename)
```
    Create a MessageSource for the given basename, to be used as MessageSource for the corresponding theme.
    Default implementation creates a ResourceBundleMessageSource. for the given basename. A subclass could create a specifically configured ReloadableResourceBundleMessageSource, for example.
    Parameters:
    basename - the basename to create a MessageSource for
    Returns:
    the MessageSource
    See Also:
    ResourceBundleMessageSource, ReloadableResourceBundleMessageSource
  - initParent
```
protected void initParent(Theme theme)
```
    Initialize the MessageSource of the given theme with the one from the corresponding parent of this ThemeSource.
    Parameters:
    theme - the Theme to (re-)initialize
