要基于两个日期参数导出到Excel，可以使用Apache POI库。以下是一个示例代码，说明了如何使用Apache POI在Java中导出带有两个日期参数的数据到Excel：

import org.apache.poi.ss.usermodel.*;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;

import java.io.FileOutputStream;
import java.io.IOException;
import java.time.LocalDate;
import java.time.format.DateTimeFormatter;

public class ExcelExporter {

    public static void main(String[] args) {
        String startDate = "2022-01-01";
        String endDate = "2022-01-31";
        DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd");
        LocalDate start = LocalDate.parse(startDate, formatter);
        LocalDate end = LocalDate.parse(endDate, formatter);

        try (Workbook workbook = new XSSFWorkbook()) {
            Sheet sheet = workbook.createSheet("Date Range");

            // Create header row
            Row headerRow = sheet.createRow(0);
            Cell headerCell1 = headerRow.createCell(0);
            headerCell1.setCellValue("Date");
            Cell headerCell2 = headerRow.createCell(1);
            headerCell2.setCellValue("Day of Week");

            // Populate data rows
            int rowNum = 1;
            while (start.isBefore(end) || start.isEqual(end)) {
                Row row = sheet.createRow(rowNum++);
                Cell cell1 = row.createCell(0);
                cell1.setCellValue(start.format(formatter));
                Cell cell2 = row.createCell(1);
                cell2.setCellValue(start.getDayOfWeek().toString());
                start = start.plusDays(1);
            }

            // Auto-size columns
            sheet.autoSizeColumn(0);
            sheet.autoSizeColumn(1);

            // Save workbook to file
            try (FileOutputStream fileOut = new FileOutputStream("date_range.xlsx")) {
                workbook.write(fileOut);
                System.out.println("Excel file exported successfully!");
            } catch (IOException e) {
                e.printStackTrace();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}

此代码将在项目目录下创建一个名为"date_range.xlsx"的Excel文件，其中包含从起始日期到结束日期的日期范围和对应的星期几。
