vue3中pdf打印问题处理

1 get请求参数问题
之前的请求是post得不到参数，今天发现的问题很奇怪，从前端进入网关，网关居然得不到参数。
前端代码

const print = () => {
    let linkUrlStr = proxy.$tool.getUrlStr(proxy.$api.invOrder.psiInvOrder.printSalOutstock,{
        asId:userInfo.value.currentAsId,
        recvStatus:condForm.value.recvStatus,
        busiType:condForm.value.busiType,
        startBillDate:condForm.value.billDateRange[0],endBillDate:condForm.value.billDateRange[1],
        token:proxy.$tool.cookie.get(sysConfig.TOKEN_NAME),
        Group : 'eayc',
        Tenat : 'psi',
    })
    window.open(linkUrlStr,'_blank');
}
tool.getUrlStr = (url,params) => {
	//对象 拼接成 & 字符串
	if (!params) return url;
	let result = url + "?";
	params &&
		Object.keys(params).forEach(
		(item) => (result += `${item}=${params[item]}&`)
		);
	return result.slice(0, -1);
}

浏览器新打开页面可以看到参数

但进去到网关后，

查看一个正确案例的如下,uri应该是要有参数的

直接讲请求参数复制到地址栏，是可以访问到数据的。但因为是get请求，时间需要做转换.使用@DateTimeFormat(pattern = "yyyy-MM-dd")

2 pdf页面样式问题
pdf是通过easyexcel先生成excel，然后再转为pdf。

    @Override
    public void print(OutputStream outputStream, String pathName, PsiInvOrderDto psiInvOrderDto) {
        Resource resource = new ClassPathResource(pathName);
        InputStream inputStream = null;
        String fileName = DateUtil.getDateRandom() + ".xls";
        File file = new File(TmpDic.url + File.separator + fileName);
        try {
            inputStream = resource.getInputStream();
            FileUtils.copyInputStreamToFile(inputStream, file);
        } catch (IOException e) {
            e.printStackTrace();
        }
        ExcelWriter excelWriter = EasyExcel.write(outputStream).withTemplate(file).build();
        WriteSheet writeSheet = EasyExcel.writerSheet(0)
                //单元格
                .registerWriteHandler(new NoRedStyleCellHander())
                .build();
        FillConfig fillConfig = FillConfig.builder().forceNewRow(Boolean.TRUE).build();
        excelWriter.fill(psiInvOrderDto.getOrderDetails(), fillConfig, writeSheet);
        excelWriter.fill(psiInvOrderDto, writeSheet);
        excelWriter.finish();
        file.delete();
    }

设置单元格样式

@Slf4j
public class NoRedStyleCellHander implements CellWriteHandler {

    /**
     * 样式类
     */
    private CellStyle cellStyle;

    @Override
    public void beforeCellCreate(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, Row row, Head head, Integer integer, Integer integer1, Boolean aBoolean) {
    }

    @Override
    public void afterCellCreate(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, Cell cell, Head head, Integer integer, Boolean aBoolean) {
    }

    @Override
    public void afterCellDataConverted(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, CellData cellData, Cell cell, Head head, Integer integer, Boolean aBoolean) {

    }

    @Override
    public void afterCellDispose(WriteSheetHolder writeSheetHolder, WriteTableHolder writeTableHolder, List<CellData> list, Cell cell, Head head, Integer integer, Boolean aBoolean) {
        if (cellStyle == null) {
            cellStyle = writeSheetHolder.getSheet().getWorkbook().createCellStyle();
        }
        if (cellStyle!=null){
            //背景颜色
            cellStyle.setFillPattern(FillPatternType.SOLID_FOREGROUND);
            cellStyle.setFillForegroundColor(IndexedColors.WHITE.getIndex());
            // 下边框
            cellStyle.setBorderBottom(BorderStyle.THIN);
            // 左边框
            cellStyle.setBorderLeft(BorderStyle.THIN);
            // 上边框
            cellStyle.setBorderTop(BorderStyle.THIN);
            // 右边框
            cellStyle.setBorderRight(BorderStyle.THIN);
            Font font = writeSheetHolder.getSheet().getWorkbook().createFont();
            font.setBold(true);
            cellStyle.setFont(font);
            //设置金额格式
            if (cell.getCellType() == CellType.NUMERIC.getCode()) {
                Workbook workbook = cell.getSheet().getWorkbook();
                DataFormat dataFormat = workbook.createDataFormat();
                cellStyle.setDataFormat(dataFormat.getFormat("#,##0.00"));
            }
            cell.setCellStyle(cellStyle);
        }
    }
}

得到的是这样的pdf,可以看到合并单位格的地方都是漆黑一片.如果上面的代码没有添加.registerWriteHandler(new NoRedStyleCellHander()),则是一片漆黑

原本我的excel模板是这样的,那么如何解决这个问题呢？
