Java調用海康雙目攝像頭SDK

使用Java調用海康的SDK人臉監控，實現智能考勤。

項目使用Springboot構建，海康攝像頭爲雙目攝像頭。

部分代碼如下：

package com.swf.attence.hikConfig;

import com.sun.jna.NativeLong;
import com.sun.jna.Pointer;
import org.dom4j.DocumentException;
import org.springframework.stereotype.Component;
import java.io.UnsupportedEncodingException;
import java.util.HashMap;
