            int byteCount = 0;
            byte[] bytes = new byte[1024];
            while ((byteCount = is.read(bytes)) > 0) {
                fout.write(bytes, 0, byteCount);

            fout.close();
            is.close();
        }
    }
 
}

上面是使用pdfbox-2.0.11.jar进行pdf转word的代码，和对pdf中图片的读取写入到文件系统，附带pom配置
