Apache POI :使用SOLID_FILL pattern在conditionalFormatting中设置前景色时出现问题

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

public class ConditionalFormattingExample {
    public static void main(String[] args) {
        // 创建工作簿和工作表
        Workbook workbook = new XSSFWorkbook();
        Sheet sheet = workbook.createSheet("Sheet1");

        // 创建条件格式规则
        SheetConditionalFormatting conditionalFormatting = sheet.getSheetConditionalFormatting();
        ConditionalFormattingRule rule = conditionalFormatting.createConditionalFormattingRule(ComparisonOperator.EQUAL, "0");

        // 创建填充模式
        PatternFormatting patternFormatting = rule.createPatternFormatting();
        patternFormatting.setFillPattern(FillPatternType.SOLID_FOREGROUND);
        patternFormatting.setFillForegroundColor(IndexedColors.RED.getIndex());

        // 创建条件格式区域
        CellRangeAddress[] regions = {CellRangeAddress.valueOf("A1:A10")};

        // 应用条件格式规则到区域
        conditionalFormatting.addConditionalFormatting(regions, rule);

        // 保存工作簿
        try {
            FileOutputStream fileOut = new FileOutputStream("workbook.xlsx");
            workbook.write(fileOut);
            fileOut.close();
            workbook.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
