javafx - javafx 的 UnsatisfiedLinkError

Question

我正在尝试学习javafx。我有一个非常简单的程序，可以在主方法(作为测试)和应用程序中打印一次“Hello World”。代码如下所示:

import javafx.stage.*;
import javafx.application.*;

public class HelloApp extends Application
{
    public static void main(String[] args)
    {
        System.out.println("Hello World");
        launch(args);
    }

    public void start(Stage stage)
    {
        System.out.println("Hello World");
    }
}

这给了我以下输出。请注意，它打印第一个“Hello World”，但不打印第二个。

我不知道为什么会发生这种情况。我的项目中有javafx的jar文件。有人可以解释一下为什么会发生这种情况以及我能做些什么吗？

如果您使用 eclipse，请添加 C:\Program Files\Oracle\JavaFX Runtime\lib\jfxrt.jar 作为外部 jar 并重建项目。
