实现方式

Java实现

public static VBox demo1() {
   VBox vBox = new VBox();
   vBox.setPadding(new Insets(10, 10, 5, 20));
    Label label = build();
    label.setBorder(new Border(new BorderStroke(Paint.valueOf("red"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
    label.setText("这是一个测试数据,测试一下换行数据,越野与呜呜呜呜测试，多行越界");
    label.setAlignment(Pos.CENTER_RIGHT);
    label.setTextAlignment(TextAlignment.RIGHT);
    vBox.getChildren().add(label);

    label = build();
    label.setBorder(new Border(new BorderStroke(Paint.valueOf("blue"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
    label.setText("单行数据");
    label.setAlignment(Pos.CENTER_LEFT);
    label.setTextAlignment(TextAlignment.RIGHT);
    vBox.getChildren().add(label);

    label = new Label();
    label.setBorder(new Border(new BorderStroke(Paint.valueOf("green"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
    label.setText("这是一个测试数据，测试数据多行捕不越界");
    label.setAlignment(Pos.CENTER_RIGHT);
    label.setTextAlignment(TextAlignment.RIGHT);
    vBox.getChildren().add(label);
    return vBox;
}

private static Label build() {
    Label label = new Label();
    label.setBorder(new Border(new BorderStroke(Paint.valueOf("red"), BorderStrokeStyle.SOLID, new CornerRadii(20), new BorderWidths(3))));
    label.setPadding(new Insets(5, 10, 5, 10));
    label.setTooltip(new Tooltip("测试Tooltip"));
    label.setText("测试数据");
    label.setAlignment(Pos.CENTER_RIGHT);
    label.setTextAlignment(TextAlignment.RIGHT);

    label.setMinWidth(100);
    label.setPrefWidth(100);
    label.setMaxWidth(200);

    label.setMinHeight(50);
    label.setPrefHeight(50);
    label.setMaxHeight(100);

    label.setWrapText(true);
    label.setEllipsisString("^^^^^^");
    return label;
}

fxml实现

 <Label alignment="CENTER" ellipsisString="^^^^^^" maxHeight="100" maxWidth="200" prefHeight="50" prefWidth="100"
       text="这是一个测试数据，测试一下换行数据" textAlignment="RIGHT" textFill="#877f3a"
       underline="true" wrapText="true">
    <padding>
        <Insets bottom="10.0" left="10.0" right="10.0" top="10.0"/>
    </padding>
    <font>
        <Font name="Arial Bold" size="14.0"/>
    </font>
</Label>
