JavaFX 8 - 如何将 TextField 文本属性绑定到 TableView 整数属性

假设我有这样的情况：我有一个TableView（表作者）有两个TableColumns（身份证号和姓名）。

这是 AuthorProps POJO，由TableView:

import javafx.beans.property.SimpleIntegerProperty;
import javafx.beans.property.SimpleStringProperty;


public class AuthorProps {
    private final SimpleIntegerProperty authorsId;
    private final SimpleStringProperty authorsName;


    public AuthorProps(int authorsId, String authorsName) {
        this.authorsId = new SimpleIntegerProperty(authorsId);
        this.authorsName = new SimpleStringProperty( authorsName);
    }

    public int getAuthorsId() {
        return authorsId.get();
    }

    public SimpleIntegerProperty authorsIdProperty() {
        return authorsId;
    }

    public void setAuthorsId(int authorsId) {
        this.authorsId.set(authorsId);
    }

    public String getAuthorsName() {
        return authorsName.get();
    }

    public SimpleStringProperty authorsNameProperty() {
        return authorsName;
    }

    public void setAuthorsName(String authorsName) {
        this.authorsName.set(authorsName);
    }
}

假设我有两个TextFields（txtId 和 txtName）。现在，我想将表格单元格中的值绑定到TextFields.

 tableAuthors.getSelectionModel()
                .selectedItemProperty()
                .addListener((observableValue, authorProps, authorProps2) -> {
                    //This works:
                    txtName.textProperty().bindBidirectional(authorProps2.authorsNameProperty());
                    //This doesn't work:
                    txtId.textProperty().bindBidirectional(authorProps2.authorsIdProperty());
                });

我可以绑定姓名TableColumn到txt名称TextField因为authorsNameProperty is a SimpleStringProperty，但我无法绑定IdTableColumn到 txtIdTextField因为authorsIdProperty is a SimpleIntegerProperty。我的问题是：如何将 txtId 绑定到 IdTableColumn?

附：如果有必要，我可以提供工作示例。

Try:

txtId.textProperty().bindBidirectional(authorProps2.authorsIdProperty(), new NumberStringConverter());
