如何通过apache poi在excel中设置字体颜色rgb

// 创建或获取单元格对象
Cell cell = sheet.getRow(rowNumber).getCell(cellNumber);

// 创建新的字体对象
Font font = workbook.createFont();

// 设置字体颜色
font.setColor(new XSSFColor(new java.awt.Color(255, 0, 0))); // 设置为红色(RGB: 255, 0, 0)

// 将字体应用于单元格
CellStyle cellStyle = workbook.createCellStyle();
cellStyle.setFont(font);
cell.setCellStyle(cellStyle);

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

import java.io.FileOutputStream;
import java.io.IOException;

public class ExcelFontColorExample {
    public static void main(String[] args) {
        Workbook workbook = new XSSFWorkbook();
        Sheet sheet = workbook.createSheet("Sheet1");

        // 创建或获取单元格对象
        Cell cell = sheet.createRow(0).createCell(0);
        cell.setCellValue("Hello, World!");

        // 创建新的字体对象
        Font font = workbook.createFont();

        // 设置字体颜色
        font.setColor(new XSSFColor(new java.awt.Color(255, 0, 0))); // 设置为红色(RGB: 255, 0, 0)

        // 将字体应用于单元格
        CellStyle cellStyle = workbook.createCellStyle();
        cellStyle.setFont(font);
        cell.setCellStyle(cellStyle);

        // 保存Excel文档
        try (FileOutputStream fileOut = new FileOutputStream("workbook.xlsx")) {
            workbook.write(fileOut);
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            try {
                workbook.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}
