How to get the default ResourceBundle regardless of current default Locale
提问by
I have three resource files in class path:
我在类路径中有三个资源文件：
labels.properties:
标签.属性：
language = Default
labels_en.properties:
label_en.properties:
language = English
labels_fr.properties:
标签_fr.properties：
language = French
Is there a way to get a ResourceBundleobject that always loads labels.propertiesNO MATTER what my default Localeis?
有没有办法获得一个ResourceBundle始终加载的对象，labels.properties无论我的默认值Locale是什么？
ResourceBundle.getBundle("labels")returns the one corresponding to the current default locale (as expected).
ResourceBundle.getBundle("labels")返回对应于当前默认语言环境的那个（如预期的那样）。
The only way I can find is to set the default locale to a non-existing locale, but this may break other modules.
我能找到的唯一方法是将默认语言环境设置为不存在的语言环境，但这可能会破坏其他模块。
Thank you!
谢谢！
Locale.setDefault( Locale.ENGLISH);
Assert.assertEquals( "English", ResourceBundle.getBundle( "labels").getString( "language"));
Locale.setDefault( Locale.FRENCH);
Assert.assertEquals( "French", ResourceBundle.getBundle( "labels").getString( "language"));
Assert.assertEquals( "French", ResourceBundle.getBundle( "labels", new Locale( "do-not-exist")).getString( "language"));
Locale.setDefault( new Locale( "do-not-exist"));
Assert.assertEquals( "Default", ResourceBundle.getBundle( "labels").getString( "language"));

You can pass in a ResourceBundle.Controlwhich, regardless of requested Locale, always searches only the root ResourceBundle:
您可以传入一个ResourceBundle.Control，无论请求的区域设置如何，它始终只搜索根 ResourceBundle：
ResourceBundle rootOnly = ResourceBundle.getBundle("labels",
new ResourceBundle.Control() {
@Override
public List<Locale> getCandidateLocales(String name,
Locale locale) {
return Collections.singletonList(Locale.ROOT);
}
});

Another way is to set the default locale of your application, like
另一种方法是设置应用程序的默认语言环境，例如
Locale.setDefault(Locale.US);
