1，采坑備忘

（1）8.1版本的SDK在spring-boot接口訪問第一次正常，第二次之后JVM會奔潰，可能是java gc 處理C++開出的內存有問題。

? ? ? ? 換6.1.3版本的SDK。

java+Windows百度離線人臉識別SDK6.1.3-Java文檔類資源-CSDN下載java+Windows百度離線人臉識別SDK6.1.3。支持spring-boot集成。更多下載資源、學習資料請訪問CSDN下載頻道.https://download.csdn.net/download/zj850324/87347677

（2）6.1.3版本SDK無法加載BaiduFaceApi.dll。依賴vc_redist.x64 2013，包里給的是2015。
