无论当前的默认语言环境如何，如何获取默认 ResourceBundle
我在类路径中有三个资源文件:
I have three resource files in class path:
labels.properties:
labels.properties:
language = Default
labels_en.properties:
labels_en.properties:
language = English
labels_fr.properties:
labels_fr.properties:
language = French
有没有办法获得一个始终加载 labels.properties 的 ResourceBundle 对象，无论我的默认 Locale 是什么?
Is there a way to get a ResourceBundle object that always loads labels.properties NO MATTER what my default Locale is?
ResourceBundle.getBundle("labels") 返回与当前默认语言环境对应的那个(如预期的那样).
ResourceBundle.getBundle("labels") returns the one corresponding to the current default locale (as expected).
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.
The only way I can find is to set the default locale to a non-existing locale, but this may break other modules.
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"));
推荐答案
你可以传入一个ResourceBundle.Control，无论请求的语言环境如何，始终只搜索根 ResourceBundle:
You can pass in a ResourceBundle.Control which, regardless of requested Locale, always searches only the root ResourceBundle:
ResourceBundle rootOnly = ResourceBundle.getBundle("labels",
new ResourceBundle.Control() {
@Override
public List<Locale> getCandidateLocales(String name,
Locale locale) {
return Collections.singletonList(Locale.ROOT);
}
});
