首先下载Adobe Acrobat DC工具：链接: https://pan.baidu.com/s/18iWctdrF0Nz07i8in6cf0A 提取码: syju 通过工具打开pdf母版，点击创建表单，然后插入文本，文本变量就是我们java代码中需要插入的值，文本域可以设置字体，颜色大小等信息**upload= upload = ...= .= .= upload= = = = .= ..:
md5 = md5 = .....= .= .i = i < .i++i= i= md5.= i = i < .i++= i& < ....= .i = i < .i++i= i^ = = ..+ ..+ ..+ ..+
网络图片转PDF，//pngPath：网络图片地址PdfUtilImgUtilpu=newPdfUtilImgUtil();//获取证书编号StringimageName=redisUtil.get(CacheConstants.CACHE_CERT_TEMP+qcr.getId());//创建临时文件Fileupload=null;try{upload=File.createTempFile(i
思路：通过背景图和二维码的合成实现//content:需要生成二维码的内容//返回图片的base64效果privateStringshareQrCode(Stringcontent){Stringpath="/template/background.png";InputStreaminputStream=this.getClass().getResourceAsStream(path);QrCon
list转map
