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.

方法详细资料

setParentThemeSource

public void setParentThemeSource(@Nullable
                                 ThemeSource parent)

从接口复制的说明: HierarchicalThemeSource

Set the parent that will be used to try to resolve theme messages that this object can't resolve.

指定者:

setParentThemeSource 在接口中 HierarchicalThemeSource

参数:

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

@Nullable
public ThemeSource getParentThemeSource()

从接口复制的说明: HierarchicalThemeSource

Return the parent of this ThemeSource, or null if none.

指定者:

getParentThemeSource 在接口中 HierarchicalThemeSource

setBasenamePrefix

public void setBasenamePrefix(@Nullable
                              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.

ResourceBundle.getBundle(String)

setDefaultEncoding

public void setDefaultEncoding(@Nullable
                               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.

从以下版本开始:

4.2

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".

4.2

AbstractResourceBasedMessageSource.setFallbackToSystemLocale(boolean)

setBeanClassLoader

public void setBeanClassLoader(@Nullable
                               ClassLoader beanClassLoader)

指定者:

setBeanClassLoader 在接口中 org.springframework.beans.factory.BeanClassLoaderAware

getTheme

@Nullable
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.

指定者:

getTheme 在接口中 ThemeSource

参数:

themeName - the name of the theme

返回:

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.

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.

参数:

basename - the basename to create a MessageSource for

返回:

the MessageSource

initParent

protected void initParent(Theme theme)

Initialize the MessageSource of the given theme with the one from the corresponding parent of this ThemeSource.

参数:

theme - the Theme to (re-)initialize
