人脸识别开发demo

开发前准备：

开发使用到的软件和工具：
Jdk8(64位，Oracle版本)、mysql5.73、spring boot、mybatis
{libarcsoft_face.dll(so)、libarcsoft_face_engine.dll(so)、libarcsoft_face_engine_jni.dll(so)}这些可以去官网下载。
其中里面的配置文件路径，io文件路径需要修改

数据表的配置

部分代码展示

• sprinh boot启动器

package com.facedemo;
@SpringBootApplication
@MapperScan({"com.gxd.facedemo.dao.mapper","com.gxd.facedemo.mapper"})
@EnableTransactionManagement
@EnableSwagger2Doc
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

• 配置文件设置

config.arcface-sdk.app-id=91BifrT9RHbUENePMKBKpCVv8TivpeUsViUwcREygaw1
# win
# config.arcface-sdk.sdk-lib-path=C:/facelib
# config.arcface-sdk.sdk-# key=7HSLAwHDNQy8XyVaqjjBxERtmfZA5btoqhmNGQEYSo8Y
# linux
config.arcface-sdk.sdk-lib-path=/usr/lib64
config.arcface-sdk.sdk-key=7HSLAwHDNQy8XyVaqjjBxERtdYz3QzutFqyRXsdMHRrj
config.arcface-sdk.thread-pool-size=5

注意 ：此处建议修改为自己的文件路径，此处仅从参考！
