SpringBoot一个JavaFx项目在Ide上运行，当我运行Jar文件时，出现错误：ClassNotFoundException

编程问答 2022-08-13

问题描述

我用Springboot和JavaFx编写了一个小项目（jdk 8）来制作简单的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）或在提示符cmd上运行，它不起作用，并且出现此问题：

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