As far as I remember the Bundleclass will lookup by default on the current ClassLoaderto find your resource. If you want to look a file on the filesystem, please use that instead:
据我所知，Bundle该类将默认在当前ClassLoader查找您的资源。如果要查看文件系统上的文件，请改用它：
File file = new File("the path of the folder containing the bundles");
URL[] urls = new URL[]{file.toURI().toURL()};
ClassLoader loader = new URLClassLoader(urls);
ResourceBundle rb = ResourceBundle.getBundle("the bundle name", your_locale, loader);

ResourceBundle.getBundle("../../resources/basic",new Locale("fr", "CA"));
change the first argument to fully qualified class name and make sure that basic_fr_CA.properties exists.
将第一个参数更改为完全限定的类名，并确保 basic_fr_CA.properties 存在。
for example if your file is at
例如，如果您的文件位于
/resource/basic_fr_CA.properties location,
then change your java code to
然后将您的java代码更改为
ResourceBundle.getBundle("resources.basic",new Locale("fr", "CA"));
