Java⼀键⽣成PDF合同以及骑缝章、盖章处的精准盖章
最近项⽬做到根据订单⽣成pdf合同。要求像阿⾥云的合同⼀样，有骑缝章，并且合同末尾处要进⾏盖章。为了做出这个功能搜集了很多博主的内容，最后终于做出了。现在做⼀个从头到尾的详细总结，也供⼤家参考⼀下，免得向我⼀样搜罗太多资料，浪费时间。废话不多说 直接开始上代码。第⼀次写博客，可能有表达的不好的地⽅，望见谅。不明⽩的可以私信，看到了尽量解答。

1、准备⼀个word格式的模板，主要内容如下：
2、⽣成和同类
* @return: java.lang.String 返回云端地址
**/
private String makeCont(List<OrderInfo> orderInfos, ContInfo contInfo) throws Exception {
String urlPath;
String id = ContFileName();// 合同ID
String contractPath = Property("ur.dir") + "/website/cont/templet/";
/
/获取合同信息
Map<String, String> replaceMap = getReplaceMap(contInfo, orderInfos);
String urId = ("urId");
StringBuilder destPathDOCX = new StringBuilder(contractPath).append(urId); //合同信息填充后的保存路径
// 判断⽤户⽂件夹是否存在，不存在则新建
File urNumFile = new String());
if (!ists()) {
urNumFile.mkdirs();
}
destPathDOCX.append(File.parator).append(urId).append(".docx");
Map<String, String> replaceTableMap = new HashMap<String, String>();
replaceTableMap.put("totalAmount", ve("totalAmount"));
replaceTableMap.put("date", ve("date"));
replaceTableMap.put("totalCapitalizeAmount", ve("totalCapitalizeAmount"));
// 替换合同⾥⾯的参数
郭玉成placeAndGenerateWord(contractPath + "templet.docx", String(), replaceMap, replaceTableMap); //更新合同中的产品服务信息
String(), orderInfos);
//设置转换后pdf⽂件的保存路径
StringBuilder pdfFile = new StringBuilder(contractPath).append(urId).append(File.parator).append(id).append(".pdf");
// 将word转pdf⽂件
Boolean bool = WordUtil.String(), String());
//盖章
InputStream inputStream = new String());
PdfUtil.itextPDFAddPicture(inputStream, String());
//将盖章后的pdf⽂档保存到云端
urlPath = aliyunOSS.uploadFile("files/contract/", id + ".pdf", new String()));
// 删除word电⼦合同
File fileDOCX = new String());
if (ists()) {
fileDOCX.delete();
}
//删除pdf电⼦合同
File filePdf = new String());
if (ists()) {
filePdf.delete();
}
return urlPath;
}
