javafx如何使用复选框在表视图中获取选定行数据

在这个项目中，我无法得到控制台输出中是否选中了复选框数据

我的代码：

    final BorderPane root = new BorderPane();

    table.setItems(createData());
    final TableColumn<Player, String> firstNameColumn = new TableColumn<>("First Name");
    final TableColumn<Player, String> lastNameColumn = new TableColumn<>("Last Name");
    final TableColumn<Player, Boolean> injuredColumn = new TableColumn<>("Injured");

    lastNameColumn.setCellValueFactory(new PropertyValueFactory<Player, String>("lastName"));
    injuredColumn.setCellValueFactory(new PropertyValueFactory<Player, Boolean>("injured"));
    final Callback<TableColumn<Player, Boolean>, TableCell<Player, Boolean>> cellFactory = CheckBoxTableCell.forTableColumn(injuredColumn);
    injuredColumn.setCellFactory(new Callback<TableColumn<Player, Boolean>, TableCell<Player, Boolean>>() {
      @Override
      public TableCell<Player, Boolean> call(TableColumn<Player, Boolean> column) {
        TableCell<Player, Boolean> cell = cellFactory.call(column);
        cell.setAlignment(Pos.CENTER);
        return cell ;
      }
    });
    injuredColumn.setCellFactory(cellFactory);
    injuredColumn.setEditable(true);

    // This appears not to get invoked:
    injuredColumn.setOnEditCommit(new EventHandler<TableColumn.CellEditEvent<Player,Boolean>>() {
      @Override
      public void handle(CellEditEvent<Player, Boolean> event) {
        System.out.println("Edit commit");
      }
    });

    table.setEditable(true);
    table.getColumns().addAll(firstNameColumn, lastNameColumn, injuredColumn);

    root.setCenter(table);

    Button button = new Button("Dump info");
    button.setOnAction(new EventHandler<ActionEvent>() {
      @Override
      public void handle(ActionEvent event) {
        for (Player p : table.getItems()) {
          System.out.println(p);
        }
        System.out.println();
      }
    }); Button button1 = new Button("add");
    button1.setOnAction(new EventHandler<ActionEvent>() {
      @Override
      public void handle(ActionEvent event) {
  data.add(new Player("hbghj", "hjhbbccc77", true));
      }
    });
    root.setBottom(button); 
    root.setTop(button1);
    primaryStage.setScene(new Scene(root, 400, 600));
    primaryStage.show();    
  }

  public static void main(String[] args) {
    launch(args);
  }

  private ObservableList<Player> createData() {
    List<Player> players = Arrays.asList(
        new Player("Hugo" ,"Lloris", false),
        new Player("Brad", "Friedel", false),
        new Player("Kyle", "Naughton", false),
        new Player("Younes", "Kaboul", true),
        new Player("Benoit", "Assou-Ekotto", false),
        new Player("Jan", "Vertonghen", false),

    );
  data =  FXCollections.<Player>observableArrayList( 
        new Callback<Player, Observable[]>() {
          @Override
          public Observable[] call(Player player) {
            return new Observable[]{player.injuredProperty()};
          }
        }
    );
    data.addAll(players);
    data.addListener(new ListChangeListener<Player>() {
      @Override
      public void onChanged(
          javafx.collections.ListChangeListener.Change<? extends Player> change) {
        System.out.println("List changed");
        while (change.next()) {
          if (change.wasUpdated()) {
              System.out.println("What code a do here");
        System.out.println();  }
        }
      }
    });
     table.getSelectionModel().selectedItemProperty().addListener(new ChangeListener() {
            @Override
            public void changed(ObservableValue observableValue, Object oldValue, Object newValue) {
                //Check whether item is selected and set value of selected item to Label
                if (table.getSelectionModel().getSelectedItem() != null) {
                    TableView.TableViewSelectionModel selectionModel = table.getSelectionModel();
                    ObservableList selectedCells = selectionModel.getSelectedCells();
                    TablePosition tablePosition = (TablePosition) selectedCells.get(0);
                    Object val = tablePosition.getTableColumn().getCellData(newValue);
                    System.out.println("Selected Value " + val);
                    System.out.println("Selected row " + newValue);
       }
            }
        });
    return data ;
  }

  public static class Player {
    private final StringProperty firstName ;
    private final StringProperty lastName ;
    private final BooleanProperty injured ;
    Player(String firstName, String lastName, boolean international) {
      this.firstName = new SimpleStringProperty(this, "firstName", firstName);
      this.lastName = new SimpleStringProperty(this, "lastName", lastName);
      this.injured = new SimpleBooleanProperty(this, "injured", international);
    }
    public String getFirstName() { return firstName.get(); }
    public void setFirstName(String firstName) { this.firstName.set(firstName);}
    public StringProperty firstNameProperty() { return firstName ; }
    public String getLastName() { return lastName.get(); }
    public void setLastName(String lastName) { this.lastName.set(lastName); }
    public StringProperty lastNameProperty() { return lastName ; }    
    public boolean isInjuredl() { return injured.get(); }
    public void setInjured(boolean international) { this.injured.set(international); }
    public BooleanProperty injuredProperty() { return injured ; }
    @Override
    public String toString() {
      return firstName.get() + " " + lastName.get() + (injured.get()?" (injured)":"");
    }
  }
}

但它不会告诉天气复选框是否选中：

public void onChanged

我需要这样的输出：

 Selected row: Gareth    Bale   true

或

如果出现以下情况，请在您的手机上试用此功能：

  if (change.wasUpdated()) {
      String inj = (data.get(change.getFrom()).injured.getValue())?"injuried":"no longer injuried";
      System.out.println(data.get(change.getFrom()).lastName.getValue() + ", " + 
              data.get(change.getFrom()).firstName.getValue() + "  "
              + "changed his status to " + inj);
      System.out.println();  
  }

注意仅当玩家受伤时，输出才会显示，否则将为空：

所选行：Gareth捆（受伤）

所选行：Gareth Bale

将其替换为：

所选行：Gareth Bale true

所选行：Gareth Bale false

您还必须在player类中更改此函数：

public String toString() {
  return firstName.get() + " " + lastName.get() + (injured.get()?" true":" false");
}

Dump info

的点击功能中还有一个问题，它提供了完整的数据，但它不是插入mysql数据库的格式

insert-into-mysqltable value（“此处的所有数据，data1，data2，true此格式”）

或者如果您可以帮助我使用for循环逐行获取

转储信息，例如：
for（row=0；row此问题与您的原始问题无关。什么？我想知道转储信息背后的概念并更改其输出格式，请提供帮助。可能是因为您的问题要求在基本主题上提供帮助，并且您仍在这里要求更多帮助，而大多数用户通常会投反对票。
  if (change.wasUpdated()) {
      String inj = (data.get(change.getFrom()).injured.getValue())?"injuried":"no longer injuried";
      System.out.println(data.get(change.getFrom()).lastName.getValue() + ", " + 
              data.get(change.getFrom()).firstName.getValue() + "  "
              + "changed his status to " + inj);
      System.out.println();  
  }

public String toString() {
  return firstName.get() + " " + lastName.get() + (injured.get()?" true":" false");
}
