java - ListCell 不显示自定义项目

Question

我正在尝试创建自定义ListCell<Chat>，但是当我按数据填写时，主视图上的 ListView 是空的。我正在尝试结合使用 Spring Boot 和 JavaFX，如下所述：https ://github.com/turais/TuraisJavaFxExamples 。当我使用ListView<String>它时，它将按预期显示字符串列表，但ListCell<Chat>在我尝试自定义实现时不会显示我的自定义。

问题出在哪里，或者我错过了第二天找不到的东西......

主控制器：

    public class MainController {

    @FXML
    private TextField txtSearch;

    @FXML
    private ListView<Chat> lvChats;

    private ObservableList<Chat> chatsObservableList;

    @Autowired
    private ListChatCell listChatCell;


    @FXML
    public void initialize() {

    }

    @PostConstruct
    public void init() {
        this.chatsObservableList = FXCollections.observableArrayList(getTestList());

        lvChats.setItems(chatsObservableList);
        lvChats.setCellFactory(studentListView -> listChatCell);
    }

    @FXML
    public void showSettings() {

    }

    private List<Chat> getTestList() {
        List<Chat> chatList = new ArrayList<>();



        chatList.add(new Chat("Last message 1", "Chat 1", "12:09", "3"));
        chatList.add(new Chat("Last message 2", "Chat 2", "14:09", "1"));

        return chatList;
    }
}

列表单元：

    public class ListChatCell extends ListCell<Chat> {

    @FXML
    private Text txtLastMessage;

    @FXML
    private Text txtChatName;

    @FXML
    private Text txtLastMessageTime;

    @FXML
    private Text txtUnreadMessage;

    @FXML
    private Pane pane;


    @FXML
    private ImageView imgChatIcon;


    @FXML
    public void initialize() {

    }


    @Override
    protected void updateItem(Chat chat, boolean empty) {
        super.updateItem(chat, empty);

        if (empty || chat == null) {

            setText(null);
            setGraphic(null);

        } else {

            txtLastMessage.setText(chat.getLastMessage());
            txtChatName.setText(chat.getChatName());
            txtLastMessageTime.setText(String.valueOf(chat.getLastMessageTime()));
            txtUnreadMessage.setText(String.valueOf(chat.getNumberUnreadMessages()));

            imgChatIcon.setImage(new Image("tl.jpeg"));
            setText("help");
            setGraphic(pane);
        }

    }
}
