在JavaFX Scene Builder 2中导入自定义组件jar文件时没有可用的组件

标签： java javafx-8 scenebuilder

我按照this教程将.jar文件导入Scene Builder 2.选择要导入的jar后，导入对话框没有显示任何组件（作者的导入对话框显示了他的CommodityImageLabel组件）。

这是我的FXML文件：

<?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.text.*?>
<?import javafx.scene.control.*?>
<?import java.lang.*?>
<?import javafx.scene.layout.*?>
<?import javafx.scene.layout.AnchorPane?>

<fx:root prefHeight="45.0" prefWidth="45.0" type="AnchorPane" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1" fx:controller="plugin.Scrabble_GUI.view.Tile">
   <children>
      <Label id="1" fx:id="letterLabel" layoutX="16.0" layoutY="11.0" text="A">
         <font>
            <Font size="20.0" />
         </font>
      </Label>
      <Label id="2" fx:id="valueLabel" layoutX="33.0" layoutY="27.0" text="4" />
   </children>
</fx:root>

这是.java文件：

package plugin.Scrabble_GUI.view; 

import java.io.IOException;

import javafx.fxml.FXML;
import javafx.fxml.FXMLLoader;
import javafx.scene.control.Label;
import javafx.scene.layout.AnchorPane;

public class Tile extends AnchorPane {
    @FXML
    protected Label letterLabel;
    @FXML
    protected Label valueLabel;

    public Tile() {
        FXMLLoader loader = new FXMLLoader(getClass().getResource("Tile.fxml"));

        loader.setRoot(this);
        loader.setController(this);

        try {
            loader.load();
        } catch (IOException e) {
            throw new RuntimeException(e);
        }
    }

    public void setLetter(String s) {
        letterLabel.setText(s);
    }

    public void setValue(String s) {
        valueLabel.setText(s);
    }

}

将包名称更改为scrabble_gui后，这是JAR分析报告。 SceneBuilder现在尝试导入两个jar - 我做了一些代码更改并为该jar使用了一个新名称。

我改变了行

FXMLLoader loader = new FXMLLoader(getClass().getResource("Tile.fxml"));

到

FXMLLoader loader = new FXMLLoader();

    loader.setLocation(Tile.class.getResource("Tile.fxml"));
