在JavaFX中将两个类属性与TableView列绑定

我有以下课程：

public class Person {
    private final StringProperty firstName;
    private final StringProperty lastName;

    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 StringProperty getName() {
        return new SimpleStringProperty(firstName.get() + " " + lastName.get()); 
    }
}

然后我有一个TableView，在其中我在一列中显示两个名称：

@FXML
private TableView<Person> personTable;
@FXML
private TableColumn<Person, String> name;

@FXML
private void initialize() {
    name.setCellValueFactory(cellData -> cellData.getValue().getName());

    personTable.getSelectionModel().selectedItemProperty().addListener(
            (observable, oldVal, newVal) -> showDetails(newVal));
}

@FXML
个人桌面视图；
@FXML
私有表列名称；
@FXML
私有void初始化（）{
name.setCellValueFactory（cellData->cellData.getValue（）.getName（））；
personTable.getSelectionModel（）.SelectEditeProperty（）.addListener(
（可观察，旧值，新值）->显示细节（新值）；
}

现在我可以对Person对象进行更改，但它们不会显示在TableView列中。当我再次打开“编辑”窗口时，我会看到新值，但在TableView中，我会看到旧值。我能怎么办呢？

怎么办

public class Person {

    private final ReadOnlyStringWrapper name = new ReadOnlyStringWrapper();

    private final StringProperty firstName = new SimpleStringProperty();
    private final StringProperty lastName = new SimpleStringProperty();

    public Person() {

        name.bind(Bindings.concat(firstName, " ", lastName));
        // existing code...
    }

    // existing code...

    public ReadOnlyStringProperty nameProperty() {
        return name.getReadOnlyProperty();
    }

    public final String getName() {
        return name.get();
    }
}

然后你就可以做了

@FXML
private TableColumn<Person, String> name;

@FXML
private void initialize() {
    name.setCellValueFactory(cellData -> cellData.getValue().nameProperty());
}

name.setCellValueFactory(cellData -> Bindings.concat(
    cellData.getValue().firstNameProperty(),
    " ",
    cellData.getValue().lastNameProperty()));
