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*/@Overridepublic 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);//定义全局字体静态变量Font titlefont;Font headfont = null;Font headfont1 =

该用到的步骤我已经标注的很详细了，即是我自己的学习记录希望能帮到各位猿友。如有不足之处还望多多指教！
