Also you can use the wrapTextProperty. But you have to set toolbar height greater than expected button height.
您也可以使用wrapTextProperty. 但是您必须将工具栏高度设置为大于预期的按钮高度。
Button btn = new Button();
btn.wrapTextProperty().setValue(true);
// or btn.setWrapText(true);
btn.setText("Some looooooooooooong text");
Or if you want to determine exactly where the line should be wrapped, you can go this way:
或者，如果您想确定该行的确切位置，您可以这样做：
Button btn = new Button();
btn.setText("Line1\n Line2\n Line3");
Last way will work without changing toolbar height.
最后一种方法可以在不更改工具栏高度的情况下工作。

In the button text property select "switch to multi-line mode
在按钮文本属性中选择“切换到多行模式
"

From sobolev's response, you can do:
从索博列夫的回应中，您可以执行以下操作：
Button btn = new Button();
btn.setText("Line1\n Line2\n Line3");
button.textAlignmentProperty().set(TextAlignment.CENTER);
This will create 3 lines of text and allign them in the center of your button.
这将创建 3 行文本并将它们对齐到按钮的中心。

My solution is pretty much the same as the one given by the OP, but instead of Labeluses Textso it's more flexible to changes in the size of the button, as it will use as many lines as needed. If required, also one can set a wrapping width, to define a width constraint.
我的解决方案与 OP 给出的解决方案几乎相同，但不是Label使用，Text因此更改按钮的大小更灵活，因为它将根据需要使用尽可能多的行。如果需要，还可以设置环绕宽度，以定义宽度约束。
@Override
public void start(Stage primaryStage) {
Button btn = new Button();
ImageView imageView = new ImageView(new Image(getClass().getResource(<image>).toExternalForm()));
Text text=new Text("Some long text that may be line wrapped");
text.setWrappingWidth(100);
VBox vBox = new VBox(5, imageView,text);
vBox.setAlignment(Pos.CENTER);
btn.setGraphic(vBox);
btn.setContentDisplay(ContentDisplay.GRAPHIC_ONLY);
Scene scene = new Scene(new StackPane(btn), 300, 250);
primaryStage.setScene(scene);
primaryStage.show();
}

Label label= new Label("your long text here");
label.setStyle("-fx-max-width : 180px);
label.setWrapText(true);
