如何在JavaFX上为本地项目设置路径

时间：2017-07-15 07:16:55

标签： java javafx fxml

我想创建一个本地JavaFX应用程序，但我不知道如何设置文件的路径，因此当我构建jar时，我不会遇到任何问题。

我已经制作了这个jar并试图修复尽可能多的错误，但我还有一些我无法修复的错误。

这是源文件夹的pic。

这些是我的错误

Exception running application sample.Main

这是Main Parent home = FXMLLoader.load(getClass().getResource("home.fxml"));

的第21行

1 个答案:

答案 0 :(得分：0)

您的错误日志显示Caused by: java.lang.ClassNotFoundException: com.jfoenix.controls.JFXButton。这意味着无法加载fxml，因为找不到类JFXButton。我认为您的库导入jfoenix存在问题，或者您忘记在您的FXML文件中包含JFXButton导入。
