如何在jDatePicker Java中禁用日期

import java.awt.*;
import java.util.*;
import javax.swing.*;
import org.jdatepicker.*;

public class DatePickerExample {
    public static void main(String[] args) {
        JFrame frame = new JFrame("Date Picker Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setLayout(new FlowLayout());

        UtilDateModel model = new UtilDateModel();
        model.setDate(2022, 0, 1); // 设置日期范围的起始日期
        model.setSelected(true);

        JDatePanelImpl datePanel = new JDatePanelImpl(model);
        JDatePickerImpl datePicker = new JDatePickerImpl(datePanel, new DateLabelFormatter());

        // 创建自定义日期模型类的实例
        CustomDateModel customModel = new CustomDateModel();
        datePanel.getModel().setDateModel(customModel);

        frame.add(datePicker);
        frame.pack();
        frame.setVisible(true);
    }
}

// 自定义日期模型类
class CustomDateModel extends UtilDateModel {
    @Override
    public boolean isSelectableDate(Date date) {
        // 在这里定义禁用日期的规则
        Calendar calendar = Calendar.getInstance();
        calendar.setTime(date);

        // 禁用2022年1月1日之前的所有日期
        Calendar disabledDate = Calendar.getInstance();
        disabledDate.set(2022, 0, 1);

        return !calendar.before(disabledDate);
    }
}

// 日期格式化类
class DateLabelFormatter extends JFormattedTextField.AbstractFormatter {
    private String datePattern = "yyyy-MM-dd";
    private java.text.SimpleDateFormat dateFormatter = new java.text.SimpleDateFormat(datePattern);

    @Override
    public Object stringToValue(String text) throws java.text.ParseException {
        return dateFormatter.parseObject(text);
    }

    @Override
    public String valueToString(Object value) throws java.text.ParseException {
        if (value != null) {
            Calendar cal = (Calendar) value;
            return dateFormatter.format(cal.getTime());
        }

        return "";
    }
}
