JavaFX 2 et l’internationalisation

Les étapes de base (parmi d’autres) d’une internationalisation d’applications Java sont la génération de parameters Locale et le regroupement de ressources. Dans JavaFX, vous pouvez utiliser FXMLLoader#setResources() à cette fin. Voici une démo du SSCCE pour le démontrer. Les codes sont auto-descriptifs.
Structure du package de démonstration:

 bundledemo |------ BundleDemo.java |------ MyController.java |------ MyView.fxml bundles |------ MyBundle_en.properties |------ MyBundle_kg.properties 

MyBundle_en.properties

 key1=Name Surname key2=How are you? 

MyBundle_kg.properties

 key1=Aты Жөнү key2=Кандайсың? 

MyView.fxml

MyController.java

 package bundledemo; import java.net.URL; import java.util.ResourceBundle; import javafx.fxml.FXML; import javafx.fxml.Initializable; import javafx.scene.control.Label; public class MyController implements Initializable { @FXML private Label lblTextByController; private ResourceBundle bundle; @Override public void initialize(URL location, ResourceBundle resources) { bundle = resources; lblTextByController.setText(bundle.getSsortingng("key1")); } } 

BundleDemo.java

 package bundledemo; // imports are ignored. public class BundleDemo extends Application { private Stage stage; @Override public void start(Stage primaryStage) { stage = primaryStage; Button btnEN = new Button(); btnEN.setText("English"); btnEN.setOnAction(new EventHandler() { @Override public void handle(ActionEvent event) { loadView(new Locale("en", "EN")); } }); Button btnKG = new Button(); btnKG.setText("Kyrgyz"); btnKG.setOnAction(new EventHandler() { @Override public void handle(ActionEvent event) { loadView(new Locale("kg", "KG")); } }); VBox root = new VBox(20); root.getChildren().add(HBoxBuilder.create().spacing(10).style("-fx-background-color: gray").padding(new Insets(5)).children(btnEN, btnKG).build()); root.getChildren().add(new StackPane()); primaryStage.setScene(new Scene(root, 300, 250)); primaryStage.show(); } private void loadView(Locale locale) { try { FXMLLoader fxmlLoader = new FXMLLoader(); fxmlLoader.setResources(ResourceBundle.getBundle("bundles.MyBundle", locale)); Pane pane = (BorderPane) fxmlLoader.load(this.getClass().getResource("MyView.fxml").openStream()); // replace the content StackPane content = (StackPane) ((VBox) stage.getScene().getRoot()).getChildren().get(1); content.getChildren().clear(); content.getChildren().add(pane); } catch (IOException ex) { ex.printStackTrace(); } } public static void main(Ssortingng[] args) { launch(args); } } 

Capture d’écran:

Cela fonctionne pour moi:

 └───src ├───app ├───bundles // <- here the "bundles" ├───dicts ├───images ├───libs └───resources 

Dans le paquet de paquets sont

 LangBundle_en.properties LangBundle_de.properties 

Contenu de l'échantillon:

 enter_pwd=Enter your password: 

Pour les charger, j'utilise le code suivant:

 @Override public void initialize(URL location, ResourceBundle resources) { ResourceBundle lngBndl = ResourceBundle .getBundle("bundles.LangBundle", new Locale("en", "EN")); tvSetupPwd.setText(lngBndl.getSsortingng("enter_pwd")); // ... } 

Regardez mon exemple

Mettre à jour:

la solution est dans Messages.java

 /** * The class with all messages of this application. */ public abstract class Messages { private static ResourceBundle BUNDLE; private static final Ssortingng FIELD_NAME = "lookup"; private static final Ssortingng BUNDLE_NAME = "messages/messages"; private static final Ssortingng CONTROLS_BUNDLE_NAME = "com/sun/javafx/scene/control/skin/resources/controls"; public static final Ssortingng MAIN_APP_TITLE; public static final Ssortingng DIALOG_HEADER; public static final Ssortingng MAIN_CONTROLLER_CONTENT_TEXT; public static final Ssortingng MAIN_CONTROLLER_HELLO_TEXT; public static final Ssortingng MAIN_CONTROLLER_GOODBYE_TEXT; static { final Locale locale = Locale.getDefault(); final ClassLoader classLoader = ControlResources.class.getClassLoader(); final ResourceBundle controlBundle = getBundle(CONTROLS_BUNDLE_NAME, locale, classLoader, PropertyLoader.getInstance()); final ResourceBundle overrideBundle = getBundle(CONTROLS_BUNDLE_NAME, PropertyLoader.getInstance()); final Map override = getUnsafeFieldValue(overrideBundle, FIELD_NAME); final Map original = getUnsafeFieldValue(controlBundle, FIELD_NAME); //noinspection ConstantConditions,ConstantConditions,unchecked original.putAll(override); BUNDLE = getBundle(BUNDLE_NAME, PropertyLoader.getInstance()); MAIN_APP_TITLE = BUNDLE.getSsortingng("MainApp.title"); DIALOG_HEADER = BUNDLE.getSsortingng("Dialog.information.header"); MAIN_CONTROLLER_CONTENT_TEXT = BUNDLE.getSsortingng("MainController.contentText"); MAIN_CONTROLLER_HELLO_TEXT = BUNDLE.getSsortingng("MainController.helloText"); MAIN_CONTROLLER_GOODBYE_TEXT = BUNDLE.getSsortingng("MainController.goodbyeText"); } public static ResourceBundle GetBundle() { return BUNDLE; } } 

et dans PropertyLoader.java

 public class PropertyLoader extends ResourceBundle.Control { private static final Ssortingng PROPERTIES_RESOURCE_NAME = "properties"; private static final PropertyLoader INSTANCE = new PropertyLoader(); public static PropertyLoader getInstance() { return INSTANCE; } @Override public ResourceBundle newBundle(final Ssortingng baseName, final Locale locale, final Ssortingng format, final ClassLoader loader, final boolean reload) throws IllegalAccessException, InstantiationException, IOException { final Ssortingng bundleName = toBundleName(baseName, locale); final Ssortingng resourceName = toResourceName(bundleName, PROPERTIES_RESOURCE_NAME); ResourceBundle bundle = null; InputStream stream = null; if (reload) { final URL url = loader.getResource(resourceName); if (url != null) { final URLConnection connection = url.openConnection(); if (connection != null) { connection.setUseCaches(false); stream = connection.getInputStream(); } } } else { stream = loader.getResourceAsStream(resourceName); } if (stream != null) { try { bundle = new PropertyResourceBundle(new InputStreamReader(stream, StandardCharsets.UTF_8)); } finally { stream.close(); } } return bundle; } }
