公司要求作身份证识别，一开始在网上搜索java方面有Tesseract-OCR的开源技术识别率可以达到99.99%。但真正接触下来，是说这个技术识别率可以达到99.99%，但需要大量的训练数据，也就是人工智能那一套。搞了半天根本达不到理想要求。那有没有其他办法那，查找了下中国的3大巨头公司阿里，腾讯、百度都有提供身份证识别接口。那就走调用第三方的方法吧。我选择了阿里。
前提：
1、需要申请一个阿里账号，有淘宝号的用淘宝号登录也可以。
2、然后在云市场搜索“印刷文字识别-身份证”。
3、阿里免费提供500次识别。需要购买该产品。
4、产品购买成功后，获取appcode值，这个要放到header中去的。
5、就可调用用了。
需要的jar包：
Maven项目直接配置依赖就可以，非maven项目就需要导入jar包：
Commons-lang-2.4.jar、fastjson-1.2.7.jar、httpclient-4.5.6.jar、httpcode-4.4.10.jar、servlet-api.jar基本这几个就够用了。

其他的不说调用代码如下：
