我正在尝试找到一种将图像添加到JavaFx
TableView列的方法，该图像具有通过hibernate从H2数据库填充的其他列中的数据。TableView是在JavaFx Scene Builder中设计的。

到目前为止，这是我设法做到的：

控制器类：

public class HomeController implements Initializable {

    @FXML
    private TableView<NewBeautifulKiwi> KIWI_TABLE;

    @FXML
    private TableColumn<NewBeautifulKiwi, Image> KiwiId;

    @FXML
    private TableColumn<NewBeautifulKiwi, String> Kiwi;

    public ObservableList<NewBeautifulKiwi> data;

    // Initializes the controller class.
    @Override
    public void initialize(URL url, ResourceBundle rb) {

        KiwiId.setCellFactory(new Callback<TableColumn<NewBeautifulKiwi, Image>, TableCell<NewBeautifulKiwi, Image>>() {
            @Override
            public TableCell<NewBeautifulKiwi, Image> call(TableColumn<NewBeautifulKiwi, Image> param) {
                //Set up the ImageView
                final ImageView imageview = new ImageView();
                imageview.setFitHeight(50);
                imageview.setFitWidth(50);

                //Set up the Table
                TableCell<NewBeautifulKiwi, Image> cell = new TableCell<NewBeautifulKiwi, Image>() {
                    public void updateItem(NewBeautifulKiwi item, boolean empty) {
                        if (item != null) {
                            imageview.setImage("arrow.png");
                        }
                    }
                };

                // Attach the imageview to the cell
                cell.setGraphic(imageview);
                return cell;
            }

        });

        Kiwi.setCellValueFactory(new PropertyValueFactory<NewBeautifulKiwi, String>("Kiwi"));
        KIWI_TABLE.setItems(gobbledyGook());
    }

    private ObservableList<NewBeautifulKiwi> gobbledyGook() {
        data = FXCollections.observableArrayList();
        Session session = HibernateUtil.getSessionFactory().openSession();
        Transaction transaction = null;
        try {
            transaction = session.beginTransaction();
            List courses = session.createQuery("from KIWI_TABLE").list();
            for (Iterator iterator = courses.iterator(); iterator.hasNext();) {
                NewBeautifulKiwi course = (NewBeautifulKiwi) iterator.next();
                System.out.println(course.getKiwi());

                data.add(course);
            }
            transaction.commit();
        } catch (HibernateException e) {
            transaction.rollback();
            e.printStackTrace();
        } finally {
            session.close();
        }
        return data;
    }
}

我imageview.setImage("arrow.png");说那是一个错误Incopatibletypes: String cannot be converted to Image。

这是我第一次尝试将图像添加到TableView中。

从昨天开始，我一直四处张望，但现在似乎被困住了。我希望能有所帮助。我真的很感谢您的帮助。

这是创建数据库pojos的类：

@Entity(name = "KIWI_TABLE")
public class NewBeautifulKiwi implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private int KiwiId;
    private String Kiwi;

    public int getKiwiId() {
        return KiwiId;
    }

    public void setKiwiId(int KiwiId) {
        this.KiwiId = KiwiId;
    }

    public String getKiwi() {
        return Kiwi;
    }

    public void setKiwi(String Kiwi) {
        this.Kiwi = Kiwi;
    }
}

谢谢大家。
