windows 上的 JavaFx + Felix 未找到 WinPlatformFactory

Question

我有一个使用 Apache felix 和 swing 的桌面应用程序，带有嵌入式 javafx UI，javafx 正在通过 Maven 嵌入式依赖项加载到项目中，它在 mac.[=12= 上运行良好]

但是当我运行它在 windows 上时它给了我以下错误：

Answer 1

javafx is being loaded into the project by a maven embebed dependency

我不认为嵌入 javafx jar 是正确的方法，如果那是您正在做的。我猜你会遗漏一些原生部分。

而是使用 "org.osgi.framework.system.packages.extra" 机制。

你可以看看Dromber FX代码（JavaFX的模块化应用程序框架，它结合了JavaFX和OSGi；我是这个框架的作者）：

Answer 2

如果 Windows JavaFX 版本（例如来自 Gluon）与 MacOS JavaFX 版本共享（破坏），也可能会出现错误 java.lang.ClassNotFoundException: com.sun.glass.ui.win.WinPlatformFactory not found。

看似安全，MacOS JAR 似乎缺少 WinPlatformFactory.class jar 中的组件，导致与 OP 相同的错误消息。

⁨javafx.graphics⁩.jar!com⁩/sun/glass⁩/⁨ui⁩/⁨win⁩/WinPlatformFactory.class

修复：

不要对所有平台使用相同的目录
--或者--
用 Windows 版本破坏 MacOS 版本（警告： 最终可能会遭受同样和相反的命运，尽管测试似乎没有显示这一点）
