如何使用JavaFX基于日期列表创建DatePicker

import javafx.scene.control.DatePicker;
import javafx.scene.control.DateCell;
import javafx.util.Callback;
import java.time.LocalDate;
import java.util.List;
import java.util.ArrayList;

public class DatePickerExample {

    public static void main(String[] args) {
        // 1. 准备日期列表
        List<LocalDate> dateList = new ArrayList<>();
        dateList.add(LocalDate.of(2023, 10, 26));
        dateList.add(LocalDate.of(2023, 10, 28));
        dateList.add(LocalDate.of(2023, 10, 30));

        // 2. 创建自定义的dayCellFactory
        final Callback<DatePicker, DateCell> dayCellFactory = new Callback<DatePicker, DateCell>() {
            @Override
            public DateCell call(final DatePicker datePicker) {
                return new DateCell() {
                    @Override
                    public void updateItem(LocalDate item, boolean empty) {
                        super.updateItem(item, empty);

                        // 3. 重写updateItem方法，判断日期是否在列表中
                        if (empty || !dateList.contains(item)) {
                            setDisable(true);
                        }
                    }
                };
            }
        };

        // 创建DatePicker实例 (This part requires a JavaFX application setup, which is omitted for brevity)
        DatePicker datePicker = new DatePicker();

        // 4. 设置DatePicker的dayCellFactory
        datePicker.setDayCellFactory(dayCellFactory);

        // 在这里添加 JavaFX application 启动代码，将 datePicker 添加到 scene 中
        // 具体实现方式取决于您的 JavaFX 应用框架
        // 例如：
        // StackPane root = new StackPane(datePicker);
        // Scene scene = new Scene(root, 300, 250);
        // primaryStage.setScene(scene);
        // primaryStage.show();

        System.out.println("DatePicker configured.  Run a JavaFX application to see it.");
    }
}
