测试环境:

• Centos 8
• jdk14
• javaFX15
• List item

先从官网下载JavaFX 15

地址为https://gluonhq.com/products/javafx/
我这里选的是JavaFX Linux SDK

创建Java项目

1. Ctrl+Shift+p create java project
2. no building tools
3. 输入项目名

导入lib

1. unzip javafx-sdk-15. 0. 1
2. cp javafx-sdk-15. 0.1/lib/* ./lib复制javafx-sdk-15.0.1/lib下的所有文件到项目lib下
3. vscode中右键lib目录 Add Folder to Java Source Path

创建测试文件

src/App.java

public class App {
    public static void main(String[] args) throws Exception {
        MainApp.main(args);
    }
}

src/MainApp.java

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Label;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class MainApp extends Application {
    /*
     * The main() method is ignored in correctly deployed JavaFX application. main()
     * serves only as fallback in case the application can not be launched through
     * deployment artifacts, e.g., in IDEs with limited FX support. NetBeans ignores
     * main().
     *
     * @param args the command line arguments
     */
    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) throws Exception {
    	// new Label
        Label label = new Label("Hello World!");
        // create a top pane
        StackPane root = new StackPane();
        // scene
        Scene scene = new Scene(root, 600, 350);

        root.getChildren().add(label);
        stage.setScene(scene);
        stage.setTitle("javaFX");
        stage.show();
    }
}
