将复选框添加到TableView列

Question

我正在重建javafx桌面应用程序，以便应用新功能并从原始应用程序中删除无用的代码。特别是带有两列的过滤后的列表视图：名称和复选框。

到目前为止，我无法为每个行成功创建复选框，我只能在第二列中显示字符串值“ false / true”。

将第二列使用的方法从字符串更改为布尔值后，我开始遇到编译PersonTableController.class的问题...

Person.class

package com.genx;

import javafx.beans.property.SimpleStringProperty;
import javafx.beans.property.SimpleBooleanProperty;

public class Person {

    public SimpleStringProperty firstName;
    public SimpleBooleanProperty selected;

    public Person(String firstName, boolean selected) {
        this.firstName = new SimpleStringProperty(firstName);
        this.selected = new SimpleBooleanProperty(selected);
    }

    @SuppressWarnings("unused")
    public String getFirstName() {
       return firstName.get();
    }

    @SuppressWarnings("unused")
    public boolean getSelected() {
       return selected.get();
    }

    @SuppressWarnings("unused")
    public SimpleBooleanProperty selectedProperty() {
      return selected;
    }
}

PersonTablecontroller.class

package com.genx;

import javafx.collections.FXCollections;

public class PersonTableController {

    @FXML   
    TableColumn<Person, String> firstNameColumn = new TableColumn<>("Roles Names");
    @FXML   
    TableColumn<Person, Boolean> lastNameColumn = new TableColumn<>("Selected");


    /**

        ObservableList<Person> masterData = FXCollections.observableArrayList(

    lastNameColumn.setEditable(true);
    personTable.getColumns().addAll(firstNameColumn, lastNameColumn);
    personTable.setItems(masterData);

    // 1. Wrap the ObservableList in a FilteredList (initially display all data).

                }

    }

    public void generateImpex() {
        Alert warning = new Alert(AlertType.WARNING, "Generating Impex!", ButtonType.YES, ButtonType.CANCEL);
        warning.showAndWait();
    }
}

在当前状态下，由于某种原因无法找到Person.class，因此我无法编译控制器。

如果在Person.class中将Boolean属性和方法更改为String，那么我可以使用此代码对PersonTableController.class进行编译：
