使用 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，它会打印第一个“Hello World”，而不是第二个。

我不知道为什么会这样。我在项目中有 javafx 的 jar 文件。有人可以解释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 添加 C:\Program Files\Oracle\JavaFX Runtime\lib\jfxrt.jar 作为外部 jar 并重建项目。
