Java纯代码实现导出pdf合并单元格
更新时间：2023年12月28日 14:08:49 作者：Xiao5xiao122
这篇文章主要为大家详细介绍了Java如何纯代码实现导出pdf与合并单元格功能,文中的示例代码讲解详细,感兴趣的小伙伴可以跟随小编一起学习一下
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);
//定义全局字体静态变量
Font titlefont;
Font headfont = null;
Font headfont1 = null;

titlefont = new Font(font, 16, Font.BOLD);
//四号
headfont = new Font(font, 14, Font.BOLD);
headfont1 = new Font(font, 14, Font.NORMAL);
//三号
content = new Font(font, 16, Font.NORMAL);
//小四
textfont = new Font(font, 11, Font.BOLD);
textfont1 = new Font(font, 11, Font.NORMAL);
space = new Font(font, 2, Font.NORMAL);
space1 = new Font(font, 10, Font.NORMAL);
space2 = new Font(font, 30, Font.NORMAL);
space3 = new Font(font, 20, Font.NORMAL);
} catch (Exception e) {
e.printStackTrace();
}
BaseFont bf;
Font font = null;
try {
//创建字体
bf = BaseFont.createFont("STSong-Light", "UniGB-UCS2-H", BaseFont.NOT_EMBEDDED);

}

//设置PDF工作区上下左右和纸张的边距
