无论当前的默认Locale如何,如何获取默认的ResourceBundle

Question

我在类路径中有三个资源文件:

labels.properties:

language = Default

labels_en.properties:

language = English

labels_fr.properties:

language = French

有没有办法让一个ResourceBundle总是加载labels.propertiesNO MATTER 的对象我的默认值Locale是什么？

ResourceBundle.getBundle("labels") 返回与当前默认语言环境对应的一个(如预期的那样).

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.

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"));

您可以传入ResourceBundle.Control,无论请求的Locale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);
        }
    });
