上一篇我们说了java实现电子发票中的发票税号等信息识别的几种可用方案,最后博主选取了识别文件二维码的方式,而且文章最后也说了,这种有局限性,去到的信息有限,而且针对OFD格式也得继续想办法,那接下来,我们就说一下怎么处理这个问题,并且如何去识别OFD格式的发票文件中的内容:
想看上一篇思路的请看博主的这篇文章:
java实现电子发票中的发票税号等信息识别的几种可用方案
https://blog.csdn.net/Alex_81D/article/details/128923743
看看这一篇发票识别的做法:
先看一下效果:
这是原图:
![JAVA识别PDF和OFD电子发票并解析为java对象](https://imgs.yssmx.com/Uploads/2023/06/483629-1.png)
这个是识别后的效果:
![JAVA识别PDF和OFD电子发票并解析为java对象](https://imgs.yssmx.com/Uploads/2023/06/483629-2.png)
完全一致。
不卖关子了,经过全网寻找,这个文章是比较靠谱的一个:
开源地址:https://github.com/sanluan/einvoice
电子发票识别,可识别 电子普票 电子专票 文件类型支持 pdf ofd
在线识别页面 http://www.heycore.com/invoice.html
如果需要打开ofd文件,再推荐个网站:
https://inv-veri.chinatax.gov.cn/xgxz.html
直接在国家税务总局网站下载,这样ofd格式就可以打开使用了。
