}

}
我自己调用方法
public HttpResult waterMark(@RequestParam String path) throws IOException, DocumentException {
// 要输出的pdf文件
BufferedOutputStream bos = new BufferedOutputStream(new FileOutputStream(new File(path)));
Calendar cal = Calendar.getInstance();
SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
// 将pdf文件先加水印然后输出
PDFWaterMarkUtils.setWatermark(bos, "D:/abc.pdf", format.format(cal.getTime()) + " 下载使用人：" + "测试user", 16);
return HttpResult.ok();
}
报错信息
{
"timestamp": "2019-12-04T09:16:33.044+0000",
"status": 500,
"error": "Internal Server Error",
"message": "D:/abc.pdf not found as file or resource.",
"path": "/img/image"
}
有没有大佬指点迷津
