百度离线人脸识别SDK

1，采坑备忘
（1）8.1版本的SDK在spring-boot接口访问第一次正常，第二次之后JVM会奔溃，可能是java gc 处理C++开出的内存有问题。
换6.1.3版本的SDK。
java+Windows百度离线人脸识别SDK6.1.3-Java文档类资源-CSDN下载java+Windows百度离线人脸识别SDK6.1.3。支持spring-boot集成。更多下载资源、学习资料请访问CSDN下载频道.
https://download.csdn.net/download/zj850324/87347677
（2）6.1.3版本SDK无法加载BaiduFaceApi.dll。依赖vc_redist.x64 2013，包里给的是2015。
