我遇到了fx：controller问题。当我将控制器添加到fxml文件时，我得到了erorr（您可以在下面看到），如果我消除了“ fx：controller”错误，并且可以运行它，但是我需要以某种方式添加fx：controller，我想您可以为我提供帮助。没有fx：controller我什么也做不了。例如，不能使用数据进行表视图或使用按钮。 谢谢。

我的fxml文件

    <?xml version="1.0" encoding="UTF-8"?>

<?import javafx.scene.control.TableColumn?>
<?import javafx.scene.control.TableView?>
<?import javafx.scene.layout.AnchorPane?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>

<AnchorPane fx:controller:"javax.controller"  xmlns="http://javafx.com/javafx" xmlns:fx="http://javafx.com/fxml"     >
   <children>
      <AnchorPane  layoutX="-89.0" layoutY="-112.0" prefHeight="400.0" prefWidth="600.0">
         <children>
            <TableView fx:id="tableview" layoutX="122.0" layoutY="118.0" prefHeight="265.0" prefWidth="428.0">
              <columns>
                <TableColumn fx:id="colName" prefWidth="75.0" text="Name" />
                <TableColumn fx:id="colPrice" prefWidth="75.0" text="Price" />
                <TableColumn fx:id="ColQ" prefWidth="75.0" text="Quantity" />
              </columns>
            </TableView>
         </children>
      </AnchorPane>
   </children>
</AnchorPane>
