FXML Loader错误无法创建JavaFX java.lang.NoSuchMethodException和Instances

我是JavaFX的新手。我整天都在寻找这两个问题的答案。我为NoSuchMethodException找到的两个修复是确保TableView有一个fx：id，并确保它有一个没有参数的构造函数。确保我修复了这两件事。

当您取消注释FXML中的两个Inhouse行时，FXML Loader无法创建实例。我没有发布完整的代码文件，因为它们非常庞大。

FXML：

<TableView fx:id="partTable" styleClass="dataTable">
                        <columns>
                            <TableColumn text="Part ID">
                                <cellValueFactory>
                                    <PropertyValueFactory property="id" />
                                </cellValueFactory>
                            </TableColumn>
                            <TableColumn fx:id="nameColumn" text="Part Name">
                                <cellValueFactory>
                                    <PropertyValueFactory property="name" />
                                </cellValueFactory>
                            </TableColumn>
                            <TableColumn text="Inventory Level">
                                <cellValueFactory>
                                    <PropertyValueFactory property="instock" />
                                </cellValueFactory>
                            </TableColumn>
                            <TableColumn text="Price/Cost per Unit">
                                <cellValueFactory>
                                    <PropertyValueFactory property="price" />
                                </cellValueFactory>
                            </TableColumn>
                        </columns>
                        <items>
                            <FXCollections fx:factory="observableArrayList">
                                //<Inhouse name="Part 1" price="5.00" instock="5" max="10" min="1" />
                                //<Inhouse name="Part 2" price="7.00" instock="2" max="11" min="2" />
                            </FXCollections>
                        </items>
                        <sortOrder>
                            <fx:reference source="nameColumn" />
                        </sortOrder>
                    </TableView>

控制器

@FXML
TextField inhouseTextField;
@FXML
TextField outsourcedTextField;
@FXML
private TableView<Inhouse> partTable;
@FXML
private TextField partNameField;
@FXML
private TextField partInstockField;
@FXML
private TextField partPriceField;
@FXML
private TextField partMaxField;
@FXML
private TextField partMinField;
@FXML
protected void addInhouse(ActionEvent event){
    ObservableList<Inhouse> data;
    data = partTable.getItems();
    data.add(new Inhouse(partNameField.getText(),
            Integer.parseInt(partInstockField.getText()),
            Double.parseDouble(partPriceField.getText()),
            Integer.parseInt(partMaxField.getText()),
            Integer.parseInt(partMinField.getText()),
            Integer.parseInt(inhouseTextField.getText())
            ));
    partNameField.setText("");
    partInstockField.setText(String.valueOf(partInstockField));
    partPriceField.setText(String.valueOf(partPriceField));
    partMaxField.setText(String.valueOf(partMaxField));
    partMinField.setText(String.valueOf(partMinField));
    inhouseTextField.setText(String.valueOf(inhouseTextField));
}

类

public class Inhouse extends Part {
Integer machineID;

Inhouse(){

}

Inhouse(String text, int parseInt, double parseDouble, int parseInt0, int parseInt1, int parseInt2) {
    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
}
}
