如何在Java中使用Apache Poi从XSSFCellStyle中读取单元格背景颜色的RGB值

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

import java.io.FileInputStream;
import java.io.IOException;

public class ExcelColorReader {
    public static void main(String[] args) {
        try (FileInputStream file = new FileInputStream("path/to/your/excel/file.xlsx");
             Workbook workbook = new XSSFWorkbook(file)) {

            Sheet sheet = workbook.getSheetAt(0);
            Row row = sheet.getRow(0);
            Cell cell = row.getCell(0);

            if (cell != null) {
                CellStyle style = cell.getCellStyle();
                if (style instanceof XSSFCellStyle) {
                    XSSFCellStyle xssfCellStyle = (XSSFCellStyle) style;
                    byte[] rgb = xssfCellStyle.getFillForegroundColorColor().getRGB();

                    System.out.println("Background Color RGB: " + rgb[0] + ", " + rgb[1] + ", " + rgb[2]);
                }
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
