java - 如何将 AwesomeFontFX 图标包添加到 IntelliJ IDEA 中的 JavaFX 项目？

Question

我正在创建一个迷你JavaFX项目，想要使用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，但当我运行代码时，它给出了 de.jensd.fx.glyphs.fontawesome.FontAwesomeIconView 的 ClassNotFoundException。我该怎么办？

我删除了两个图标，代码运行正常。我搜索了很多地方，但只显示将 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>

Controller 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。

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

如果您使用 Maven 或 Gradle，则只需包含 FontAwesome 依赖项即可:

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

这还将包括 de.jensd:fontawesomefx-commons:11.0。

如果您不使用 Maven/Gradle，则必须从 here 下载它们和here ，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，因此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。
