Excel报表公式值替换后，报错打开提示部分内容有问题, 是否尝试尽量恢复

1、POI处理excel，替换单元格中公式，直接setValue，替换不生效

2、删除单元格，重新创建单元格，创建格式，设置值，WPS没问题，但是excel打开后直接报错 部分内容有问题，是否尝试尽量恢复

解决方案：

public static String readExcel(File file, String replaceValue) throws IOException {
        String canonicalPath = file.getCanonicalPath();
        String newFilePath = StringUtils.substringBeforeLast(canonicalPath, ".")+"_bak."+ StringUtils.substringAfterLast(canonicalPath, ".");
        try (BufferedInputStream bufferedInputStream = new BufferedInputStream(new FileInputStream(file));
             Workbook workbook  = WorkbookFactory.create(bufferedInputStream);
             OutputStream out = new FileOutputStream(newFilePath)) {
            DataFormat dataFormat = workbook.createDataFormat();
            Sheet sheet = workbook.getSheetAt(0);
            CellStyle cellStyle1 = workbook.createCellStyle();
            Row row = sheet.getRow(1);
            Cell cell1 =  row.getCell(0);
            row.removeCell(cell1);
            Cell cell = row.createCell(1);
            cellStyle1.setDataFormat(dataFormat.getFormat("yyyy/M/dd"));
            cell.setCellFormula("TODAY()"+replaceValue);
            cell.setCellStyle(cellStyle1);
            sheet.setForceFormulaRecalculation(true);
            workbook.write(out);
            out.flush();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return newFilePath;
    }
