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;

	private static final String CONTRACT = "resource/contract/";//合同文件存储路径

		htmHandler(templatePath, templateName, localHtmlUrl, paramMap);// 生成html合同
		pdfHandler(localHtmlUrl, localPdfUrl);// 根据html合同生成pdf合同
