java 纯代码导出pdf合并单元格

java 纯代码导出pdf合并单元格
接上篇博客 java导出pdf（纯代码实现） 后有一部分猿友叫我提供一下源码，实际上我的源码已经贴在帖子上了，都是同样的步骤，只是加多一点设置就可以了。今天我再次上传一下相对情况比较完整导出PDF的场景，包含列表，合并单元格，设置边框等，具体请先看效果图：
注：次效果图仅供参考，内容均为测试数据不具有任何意义。

废话不多说，直接上源码：

@SneakyThrows
    @PostMapping("/download")
    @ApiOperation(value = "模板下载")
    public void download(@RequestBody TemplateDownloadDTO downloadDTO, HttpServletRequest request, HttpServletResponse response){
		//该导出仅针对一条数据故要传id确定数据
        Assert.notNull(downloadDTO.getId(),"id必传");

        request.getSession();

        String fileName = "文件名称";

        PdfUtil.setResponseContentType(response,fileName);

        stockOutService.download(downloadDTO,response);
    }

以下为导出PDF头部设置，具体在另外一个帖子中有

public static void setResponseContentType(HttpServletResponse response, String fileName) throws UnsupportedEncodingException {
        response.setContentType("application/pdf");
        response.setCharacterEncoding("utf-8");
        response.setHeader("Content-Disposition", "attachment;filename=" + URLEncoder.encode(fileName, "utf-8") + ".pdf");
        response.setHeader("Access-Control-Expose-Headers", "Content-Disposition");
    }

以下是逻辑部分

/**
     * 调运明细模板下载
     *
     * @param downloadDTO 入参
     * @param response    返回
     */
    @Override
    public void download(TemplateDownloadDTO downloadDTO, HttpServletResponse response) {		//你自己的查询数据的逻辑部分，我这里做了删减不展示
        List<StockOutDtlVO> vos = BeanUtils.copyListPropertiesByClass(list, StockOutDtlVO.class);

        vo.setDtls(vos);

            cell7.setHorizontalAlignment(Element.ALIGN_MIDDLE);
            cell7.setBorder(0);

            table.addCell(cell6);
            table.addCell(cell7);

            document.add(table);
            document.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
