这对我来说很有用:

└───resources
样本内容:
enter_pwd=Enter your password:
要加载它们,我使用以下代码:
@Override
public void initialize(URL location, ResourceBundle resources) {
ResourceBundle lngBndl = ResourceBundle
.getBundle("bundles.LangBundle", new Locale("en", "EN"));
tvSetupPwd.setText(lngBndl.getString("enter_pwd"));
// ...

非常好的答案,我会接受它,但我应该提到,我正在用代码而不是FXML构建接口。是否有一种快速简便的代码国际化方法,我意识到我可以做ResourceBundle.getBundle+查找,但我希望可以用%键表示法来代替。然后你可以像在任何其他Java应用程序中一样,用普通的方法来做这件事。确定用户/客户机的区域设置,然后相应地更改应用程序的区域设置(从DB vs.获取特定于语言的数据)。通过ResourceBundle.getBundle(“bundles.MyBundle”,locale)
加载适当的bundle。通过bundle.getString(“key”)
更改视图/页面中使用的所有文本。如果我通过setResources()方法提供ResourceBundle,这对我不起作用。当我通过load()方法提供ResourceBundle时,它正在工作。@Jurica Krizanic:有相同的问题,并通过相同的方法解决了它:FXMLLoader.load(getClass().getResource(sceneId),getResources())
其中sceneId
是字符串和方法getResources()
返回具有正确区域设置的资源。Hello@UlukBiy我们可以在
中多次添加文本,如“%key2%key1”。因为我已经试过了,但它给了我一个例外…但我不知道它是否可能。。。!关于语言之间的切换,这里有一些信息:[[1]:@Moritz如果你点击了链接,就会看到详细的响应和完整的源文件,我在stackoverflow.com上添加了一个响应链接。因为你,我必须在所有地方插入相同的代码。我希望你喜欢,而不是不喜欢
