在Java中使用JavaFX中的命令行参数 [英] Using command line arguments in Java with JavaFX

问题描述

我有以下代码：

public class Main extends Application {

  @Override
  public void start(Stage primaryStage) throws Exception{
      Parent root = FXMLLoader.load(getClass().getResource("hive.fxml"));
      primaryStage.setTitle("Hive-viewer");
      primaryStage.setScene(new Scene(root, 1600, 900));
      primaryStage.show();
  }


  public static void main(String[] args) {
      launch(args);
  }
}

我想知道如何使用文件（在Controller中或在Main类的方法中使用命令行）

I want to know how you would use a file (given with the command line) in the Controller or in a method in the Main class

推荐答案

尝试 getParameters 。这应该给你命令行参数

Try getParameters. This should give you the command line arguments

希望一个小例子（我从拉斐尔的回答中获取主代码）

As wished a small example (i took the main code from Raphael's answer)

假设控制器类名为MyController

Assuming the controller class is named "MyController"

public class Main extends Application {

 @Override
 public void start(Stage primaryStage) throws Exception{

    FXMLLoader loader=new FXMLLoader(getClass().getResource("hive.fxml"));
    Parent root = loader.load();
    MyController cont=load.getController();
    /*
      This depends on your controller and you have to decide 
      How your controller need the arguments
    */
    cont.setParameter(getParameters()); 

    primaryStage.setTitle("Hive-viewer");
    primaryStage.setScene(new Scene(root, 1600, 900));
    primaryStage.show();
 }


 public static void main(String[] args) {
    launch(args);
 }
}
