据我了解，该异常是我的模块设置有问题，但我不清楚需要更改什么：

  • 向--add-modules中添加其他模块，哪个？
  • 将--add-opens添加到用于哪个模块的命令
  • 完全不同吗？

答案 0 :(得分：6)

JavaFX 11分为seven modules。在命令行中，您可以：

--add-modules javafx.controls,javafx.graphics

您得到的错误是：

java.lang.IllegalAccessError: class com.sun.media.jfxmediaimpl.NativeMediaManager (in unnamed module @0x4d7be377) cannot access class com.sun.glass.utils.NativeLibLoader (in module javafx.graphics) because module javafx.graphics does not export com.sun.glass.utils to unnamed module @0x4d7be377

这是在告诉您com.sun.media.jfxmediaimpl包中的一个类在未命名的模块中，并且正在尝试访问javafx.graphics模块的内部成员。程序包的名称表示它属于javafx.media模块。该错误表明，但是，您正在使用来自类路径的javafx.media模块。您需要在javafx.media命令中包含--add-modules才能从模块路径使用它：

--add-modules javafx.controls,javafx.graphics,javafx.media

由于module-info的{​​{1}}文件，此方法有效。它具有合格的javafx.graphics和/或exports伪指令，该伪指令允许opens访问那些内部包。但是，如果涉及的所有内容都在模块路径中，则模块系统只能考虑这些指令。

在相关说明中，您无需在命令中包含javafx.media，因为您已经添加了javafx.graphics。 javafx.controls和javafx.controls都需要javafx.media和javafx.graphics模块，因此会将它们插入。

当或如果使代码模块化时，您将不必处理javafx.base。您只需要声明适当的--add-modules指令：

requires

然后，您只需确保所有模块（包括您的模块）都位于module example { requires javafx.controls; // transitively requires javafx.base and javafx.graphics requires javafx.media; // transitively requires javafx.base and javafx.graphics // ... other directives ... /* * Don't forget to "exports" the package containing your Application * class to at least the javafx.graphics module. */ } （或--module-path）上。您的模块将提取必要的依赖项。

如果您使用的是 VSCode，这里有一个简单的方法可以解决您的问题：

在 java 项目中存在一个名为 .vscode 的文件夹，其中存在一个名为 launch.json 的 .json 文件。

目录： Image

launch.json：

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "java",
            "name": "Launch Main",
            "request": "launch",
            "vmArgs": "--module-path /Users/ASUS/javafx-sdk-16/lib --add-modules javafx.controls,javafx.fxml",
            "mainClass": "main.java.Main",
            "projectName": "MorseJavaFx_41229da3"
        },
        {
            "type": "java",
            "name": "Launch Current File",
            "request": "launch",
            "mainClass": "${file}"
        }
    ]
}

因此，在“vmArgs”行中，您必须将 javafx.media 添加到最后和引号内，如下所示：

"vmArgs": "--module-path /Users/ASUS/javafx-sdk-16/lib --add-modules javafx.controls,javafx.fxml, javafx.media"

享受。?
