Spring boot SpringBoot一个JavaFx项目在Ide上工作，当我运行Jar文件时，我得到错误：ClassNotFoundException

我用Springboot和JavaFx编写了一个小项目（JDK8），以创建简单的UI。 当我在IDE（STS、Eclipse、Intellij）上运行时，一切正常

当我打包到Jar文件时，我运行它（从Windows 10）或在命令提示符下，它不工作，我遇到了以下问题：

Exception in thread "main" java.lang.reflect.InvocationTargetException...
..Caused by: java.lang.ClassNotFoundException: **com.sun.javafx.scene.control.skin.BehaviorSkinBase**

post your pom file pls@Thomas Andolf我编辑了添加我的pom的问题，感谢你删除maven exec插件，然后从命令行@Thomas Andolf构建并运行jar文件，我刚刚尝试过，但我遇到了同样的问题，我收到了稍微不同的错误消息：由：net.rgielen.fxweaver.core.FxLoadException引起：无法加载FXML文件jar:file:/C:/Users/user/Documents/workspace-spring-tool-suite-4-4.5.1.RELEASE/Export-FX/target/Export-FX-0.0.1-SNAPSHOT.jar/BOOT-INF/classes/查看/导出.fxml。。。。原因：javafx.fxml.LoadException:file:/C:/Users/user/Documents/workspace-spring-tool-suite-4-4.5.1.RELEASE/Export-FX/target/Export-FX-0.0.1-SNAPSHOT.jar/BOOT-INF/classes/查看/导出.fxml。。。。。原因：java.lang.ClassNotFoundException:com.sun.javafx.scene.control.skin.BehaviorSkinBase。。。
