Spring Boot JavaFX starter

為了方便的將Spring boot 與 JavaFX結(jié)合,可以方便的在JavaFx中使用Spring boot的能力，自己寫個(gè)包發(fā)布到中央倉庫

Maven

添加以下依賴

<dependency>
    <groupId>io.github.podigua</groupId>
    <artifactId>javafx-podigua-boot-starter</artifactId>
    <version>1.0.0</version>
</dependency>

用法

創(chuàng)建一個(gè)類,繼承AbstractJavafxApplication,然后調(diào)用launch方法啟動JavaFX程序

用法1

使用普通方法啟動界面

@SpringBootApplication
public class TestApplication extends AbstractJavafxApplication {
    public static void main(String[] args) {
        launch(TestApplication.class, args);
    }

    @Override
    protected void ready(Stage stage) {
        VBox root = new VBox();
        Button button = new Button("測試");
        button.setOnAction(event -> {
            Alert alert = new Alert(AlertType.NONE, "點(diǎn)擊了按鈕", ButtonType.OK);
            alert.showAndWait();
        });
        root.getChildren().add(button);
        Scene scene = new Scene(root, 1000, 750);
        stage.setScene(scene);
        stage.show();
    }
}

用法2

使用Fxml啟動界面

啟動類

FxmlService 封裝了加載fxml文件的方法,并獲取spring容器中的對應(yīng)的bean

需要在fxml文件中聲明fx:controller

@SpringBootApplication
public class TestApplication extends AbstractJavafxApplication {
    public static void main(String[] args) {
        launch(TestApplication.class, args);
    }

    @Autowired
    private FxmlService fxmlService;

    @Override
    protected void ready(Stage stage) {
        Parent parent = fxmlService.load("fxml/index.fxml");
        stage.setScene(new Scene(parent, 1000, 750));
        stage.show();
    }
}

fxml

路徑為:fxml/index.fxml

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.AnchorPane?>
<AnchorPane xmlns="http://javafx.com/javafx"
            xmlns:fx="http://javafx.com/fxml"
            fx:controller="com.example.javafx.IndexController"
            prefHeight="400.0" prefWidth="600.0">
    <Button text="測試" onAction="#test"></Button>
</AnchorPane>

controller

controller 需要添加@Service使controller注冊為spring的bean

@Service
public class IndexController implements Initializable {
    @Override
    public void initialize(URL location, ResourceBundle resources) {
        System.out.println("initialize");
    }

    public void test(ActionEvent event) {
        Alert alert = new Alert(AlertType.NONE, "點(diǎn)擊了按鈕", ButtonType.OK);
        alert.showAndWait();
    }
}

動畫

spring boot 加載過程較慢,spring加載過程中會展示一個(gè)動畫,動畫默認(rèn)由DefaultSplashScreen提供,默認(rèn)可見

創(chuàng)建一個(gè)類實(shí)現(xiàn)SplashScreen可以修改是否可見,以及圖片的選擇,若不以圖片的方式展示,可以自行定義getParent方法

public class ImageSplashScreen implements SplashScreen {

    @Override
    public boolean visible() {
        return true;
    }

    @Override
    public String getImagePath() {
        return "start.png";
    }
}

啟動類調(diào)用launch的重載方法

@SpringBootApplication
public class TestApplication extends AbstractJavafxApplication {
    public static void main(String[] args) {
        launch(TestApplication.class, new ImageSplashScreen(), args);
    }

    @Autowired
    private FxmlService fxmlService;

    @Override
    protected void ready(Stage stage) {
        Parent parent = fxmlService.load("fxml/index.fxml");
        stage.setScene(new Scene(parent, 1000, 750));
        stage.show();
    }
}
