虹软离线人脸识别java版本的SDK使用配置，也是整了半天才看明白一些，总结一下

1首先你要到虹软的官网–注册登录
https://ai.arcsoft.com.cn/ucenter/user/userlogin

2、登录进去之后：

会让你实名认证，想使用就老老实实认证（哈哈），我这边认证过了，不贴图了。其中认证有两种：1、个人认证。2、企业认证
感觉没啥区别，可能企业审核会快一点，个人慢一点。一般2个小时都能审核通过。
3、认证完成后就可以去下载SDK了，下载之前要先创建一个应用

完成之后就能下载了！

下载完成解压就是这个样子滴：

可以把它放到想放的位置。
然后导入就可以了：这边使用的是eclipse开发工具
inport找到你的SDK导入

虹软是没有有离线人脸库的，需要你自己提取人脸特征后把人脸特征放入到数据库，或者文件中，下面随便写的例子：用Map模拟数据库
