回答by Sergey Grinev
All controls in JavaFX can be modified using CSS styling. You may want to take a look at referenceor tutorial.
JavaFX 中的所有控件都可以使用 CSS 样式进行修改。您可能需要查看参考或教程。
Gray ScrollPane's border is actually the only part of the background which is visible behind the content. So you can change it by modifying the background:
Gray ScrollPane 的边框实际上是在内容后面可见的唯一背景部分。所以你可以通过修改背景来改变它：
ScrollPane sp = new ScrollPane();
sp.setStyle("-fx-background-color:transparent;");

Or in CSS
或者在 CSS 中
.scroll-pane {
-fx-background-color:transparent;
}

In pure Java, without CSS, you need to set the background like this, which is a lot more verbose than the CSS approach.
在纯Java中，没有CSS，你需要像这样设置背景，这比CSS的方法要冗长得多。
ScrollPane scrollPane = new ScrollPane();
scrollPane.setBackground(
new Background(new BackgroundFill(Color.TRANSPARENT, null, null))
);

Making the border transparent will leave a 1 pixel gap around the edge. IMHO, the correct answer is the one that Jens Piegsa linked to. https://stackoverflow.com/a/17540428/1725096
使边框透明将在边缘周围留下 1 像素的间隙。恕我直言，正确答案是 Jens Piegsa 链接到的答案。 https://stackoverflow.com/a/17540428/1725096
