设置javafx包控制器的问题

时间:2019-06-18 05:29:23

标签: java javafx

我正在尝试组织我的项目,但是当我尝试加载控制器时,我得到了java.lang.reflect.InvocationTargetException,但是我有正确的路径。我该如何解决?

<AnchorPane id="AnchorPane" prefHeight="570.0" prefWidth="784.0" styleClass="root" xmlns:fx="http://javafx.com/fxml/1" xmlns="http://javafx.com/javafx/2.2" fx:controller="user.ui.main.StrixController">

错误

好像您的问题不在路径中

Caused by: javafx.fxml.LoadException: Error resolving onAction='#handleAboutAction', either 
the event handler is not in the Namespace or there is an error in the script.
file:/home/blackleitus/NetBeansProjects/JavaFXApplication11/dist/run981614013/JavaFXApplication11.jar!/javafxapplication11/ui/main/FXMLDocument.fxml:26

问题是加载器未在控制器中找到方法handleAboutAction 尝试检查fxml和控制器中的方法名称拼写

我希望这能奏效(如果没有告诉我)

答案 1 :(得分:0)

您缺少Event函数

   @FXML
    void handleAboutAction(ActionEvent event) {

    }
