当我尝试使用webEngine.load();
加载任何html或url时,我的webView只是空白。从我在这里读到的" JavaFX 2.2 WebView"好像我必须签署我的应用程序才能让它在沙箱模式之外运行。
http://docs.oracle.com/javafx/2/deployment/deploy_overview.htm#CEGJGHDA
这是导致这个问题的原因吗?
我正在使用NetBeans 8.1,在“项目设置”下,我将其作为独立运行。我一直在关注这些教程,每个教程都很顺利。 http://docs.oracle.com/javase/8/javafx/get-started-tutorial/get_start_apps.htm#JFXST804
这是我的三个文件。

答案 0 :(得分:1)
您还没有在FXML中指定控制器,因此永远不会执行控制器的初始化方法。
将以下属性定义添加到构成FXML根元素的VBox元素中:
fx:controller="twitchauthorize.FXMLTwitchAuthorizeController"
