Use ResourceBundlesto store the locale-dependent text, and access the data in the bundle using "%resourceKey".
使用ResourceBundles存储与语言环境相关的文本，并使用 访问包中的数据"%resourceKey"。
Specifically, create text files for each language you want to support and place them in the classpath. The Javadocs for ResourceBundlehave the details on the naming scheme, but you should have a default bundle defined by BaseName.propertiesand bundles for other languages and variants defined by BaseName_xx.properties. For example (with the resourcesdirectory in the root of the classpath):
具体来说，为您想要支持的每种语言创建文本文件并将它们放在类路径中。的JavadocsResourceBundle有关于命名方案的详细信息，但您应该有一个BaseName.properties由BaseName_xx.properties. 例如（resources在类路径的根目录中的目录）：
resources/UIResources.properties:
资源/UIResources.properties：
greeting = Hello
resources/UIResources_fr.properties:
资源/UIResources_fr.properties：
greeting = Bonjour
Then in your FXML file you can do
然后在你的 FXML 文件中你可以做
<Label text = "%greeting" />
To pass the ResourceBundleto the FXMLLoaderdo:
将 传递ResourceBundle给FXMLLoaderdo：
ResourceBundle bundle = ResourceBundle.getBundle("resources.UIResources");
FXMLLoader loader = new FXMLLoader(getClass().getResource("/path/to/FXML.fxml"), bundle);
Parent root = loader.load();
This code will load the resource bundle corresponding to the default locale (typically the locale you have set at the OS level), falling back on the default if it can't find a corresponding bundle. If you want to force it to use a particular bundle, you can do
此代码将加载与默认区域设置（通常是您在操作系统级别设置的区域设置）对应的资源包，如果找不到相应的包，则回退到默认值。如果你想强制它使用特定的包，你可以这样做
ResourceBundle bundle = ResourceBundle.getBundle("/resources/UIResources", new Locale("fr"));
Finally, if you need access to the resource bundle in the FXML controller, you can inject it into a field of type ResourceBundleand name resources:
最后，如果您需要访问 FXML 控制器中的资源包，您可以将其注入一个 typeResourceBundle和 name字段resources：
public class MyController {
@FXML
private ResourceBundle resources ;
// ...
}
