Java通过freemarker生成pdf文件并盖章

Java代码生成pdf回执文件,直接上代码:

package com.pdf;

import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.io.OutputStreamWriter;

// 组装html和pdf合同的全路径URL

// 判断本地路径是否存在如果不存在则创建
File localFile = new File(localPdfPath);
if (!localFile.exists()) {
localFile.mkdirs();
}
String localPdfUrl = localFile + "/" + PDFNAME + ".pdf";
templateName=templateName+".ftl";
htmHandler(templatePath, templateName, localHtmlUrl, paramMap);// 生成html合同
pdfHandler(localHtmlUrl, localPdfUrl);// 根据html合同生成pdf合同
deleteFile(localHtmlUrl);// 删除html格式合同

System.out.println("PDF生成成功");
}
