如何在 IntelliJ IDEA 中将 AwesomeFontFX 图标包添加到 JavaFX 项目？

Question

我正在创建一个 mini-JavaFX 项目并想使用 Awesome Font Icon Pack。我使用 Scenebuilder 加载了 fontawesomefx-8.9 并在其中打开了 FXML 并在其中加载了两个图标，还在 External 中添加了 JAR 文件IntelliJ 中的库，但是当我运行代码时，它会为 de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView 提供 ClassNotFoundException。我该怎么办？

我删除了两个图标，代码运行良好。我搜索了很多地方，但它只显示将 JAR 文件添加到外部库，什么也没有。我正在使用 JDK 12、JavaFX 12 和 Scenebuilder 11.0。

FXML 文件

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

<?import de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView?>
<?import javafx.geometry.Insets?>
<?import javafx.scene.control.Button?>
<?import javafx.scene.layout.ColumnConstraints?>
<?import javafx.scene.layout.GridPane?>
<?import javafx.scene.layout.RowConstraints?>

<fx:root alignment="center" hgap="10" type="GridPane" vgap="10" xmlns="http://javafx.com/javafx/8.0.171" xmlns:fx="http://javafx.com/fxml/1" fx:controller="sample.Controller">
   <children>
      <Button mnemonicParsing="false" text="Click Me!!!">
         <opaqueInsets>
            <Insets left="5.0" />
         </opaqueInsets></Button>
      <FontAwesomeIconView glyphName="CIRCLE" />
   </children>
   <columnConstraints>
      <ColumnConstraints />
   </columnConstraints>
   <rowConstraints>
      <RowConstraints />
   </rowConstraints>
</fx:root>

控制器类

package sample;

import javafx.fxml.Initializable;

import java.net.URL;
import java.util.ResourceBundle;

public class Controller implements Initializable {

    @Override
    public void initialize(URL url, ResourceBundle resourceBundle) {

    }

Module-Info.java

module Practice {
    requires javafx.controls;
    requires javafx.fxml;

    opens sample;
}

主类

package sample;

import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception{
        Parent root = FXMLLoader.load(getClass().getResource("sample.fxml"));
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(new Scene(root, 300, 275));
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Answer 1

由于您使用的是 Java 和 JavaFX 12，因此您应该使用有效的 FontAwesomeFX 版本：11.0.0。

你可以在这里找到它：https://bintray.com/jerady/maven/FontAwesomeFX/11.0.0

如果您使用的是 Maven 或 Gradle，您可以只包含 FontAwesome 依赖项：

dependencies {
    implementation "de.jensd:fontawesomefx-fontawesome:4.7.0-11"
}

这也将包括de.jensd:fontawesomefx-commons:11.0。

如果您不使用 Maven/Gradle，则必须从 here 和 here 下载它们，并将它们包含在您的项目中。

下一步：由于您有一个模块化应用程序，您的模块描述符应该包含您的项目需要的所有模块。

因此，您的 module-info 应该包含 fontawesome 模块：

module Practice {
    requires javafx.controls;
    requires javafx.fxml;
    requires de.jensd.fx.fontawesomefx.fontawesome;

    opens sample to javafx.fxml;
    exports sample;
}

现在您的项目将拥有所有必需的依赖项并且可以正常工作。
