Question

我有一个国际化应用程序的代码。我需要加载捆绑文件，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"));

我收到了以下错误。

如何提供正确的budle文件路径？

提前致谢！

Answer 1

据我所知，Bundle类默认会在当前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);

Answer 2

ResourceBundle.getBundle("../../resources/basic",new Locale("fr", "CA"));

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。

例如，

如果您的文件位于

/resource/basic_fr_CA.properties location,

然后将您的Java代码更改为

ResourceBundle.getBundle("resources.basic",new Locale("fr", "CA"));

Answer 3

如果你的资源在resources文件夹下，可以这样使用，这样比较好，不用处理checked异常：

ClassLoader loader = new URLClassLoader(new URL[]{ I18NManager.class.getResource("path to folder containing bundles you want to load")});
ResourceBundle rb = ResourceBundle.getBundle("the bundle name", locale);

其中 I18NManager 表示正在加载资源的类。

如果

I18NManager.class 不在静态上下文中，可以用 getClass() 替换。
