java - 如何从java中的目录获取资源包文件？

Question

我有一个国际化应用程序的代码。我需要加载 bundle 文件，从运行位置返回两次并加载它。

我的代码是，

bundle = ResourceBundle.getBundle("../../resources/basic",new Locale("fr", "CA"));
lblUsername.setText(bundle.getString("username"));
lblPassword.setText(bundle.getString("password"));
btnLogin.setText(bundle.getString("login"));

我收到以下错误。

据我所知，Bundle 类默认会在当前的 ClassLoader 上查找您的资源。如果你想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);
