ScalaFXML 应用程序找不到控制器

Question

我有一个 ScalaFX 应用程序，我正在使用 FXML 作为我的视图。我在将视图连接到控制器时遇到了麻烦。除了 Github 上的示例，我在网上找不到太多信息，即使我试图模仿他们是如何做到的，它也不起作用。以下是我在 FXML 中的连接方式。

imports...

<BorderPane maxHeight="-Infinity" maxWidth="-Infinity" minHeight="520.0" minWidth="880.0" prefHeight="520.0"
            prefWidth="880.0" xmlns="http://javafx.com/javafx/8" xmlns:fx="http://javafx.com/fxml/1"
            fx:controller="scala/scalafxml/ToolbarController">
<center....

这是我的控制器class...

@sfxml
class ToolbarController extends JFXApp {
  //open new form
   def newForm = {
    val resource = getClass.getResource("/scala/scalafxml/form.fxml")

堆栈跟踪表明它无法找到 fx:controller 引用的控制器 class。在这里。

FXML 文件位于 src/main/resources/scalafxml/calendar.fxml，控制器位于 src/main/scala/scalafxml/ToolbarController.scala.

我可能有明显的错误，因为我对 Scala 还很陌生。非常感谢任何指点。

看看这个独立的例子： https://github.com/vigoo/scalafxml-unit-converter-example

您应该有一个单独的控制器 class 和一个 JFXApp，并使用 ScalaFXML 中的FXMLView 构造函数来创建视图。
