JavaFX Spinner.getValue()

Question

我正在开发 JavaFX 表单。该表单应该获取值并将其添加到数据库中。每当我尝试通过 .getValue 获取值时，它都会产生错误

Incompatible Types: Object cannot be converted to Int

这是 FXML 代码:

<Spinner fx:id="spinner" layoutX="494.0" layoutY="528.0" maxWidth="100.0" minWidth="100.0" prefWidth="100.0">
    <valueFactory>
       <SpinnerValueFactory.IntegerSpinnerValueFactory min="0" max="30" initialValue="20" amountToStepBy="1"/>
    </valueFactory>
</Spinner>

Java 代码:

 Spinner mySpinner=(Spinner) spinner;
        int value = mySpinner.getValue;

感谢您的帮助

永远不要使用原始类型。使用类似这样的东西:

Spinner<Integer> mySpinner = (Spinner<Integer>) spinner;
