前一段时间在HR系统中做了一个人脸识别考勤的模块，主要功能：设备注册，下发卡号与人脸，获取卡号与人脸，删除卡号与人脸，对设备布防，报警回调函数。

首先在Window上开发，我们项目的JDK是1.6（64位），所以必须要用Win64的SDK开发包，这个很重要，版本对不上，在调用HCNetSDK.dll这个库文件时会报错，现在开始开发。

1.先去海康官网下载最新的SDK 官网地址：https://www.hikvision.com/cn/，下载你JDK版本对应的SDK（里面包含Java的demo），你如果不知道你的JDK对应什么SDK，可以去找海康销售跟他要海康技术支持的邮箱，你在开发过程中所有遇到的问题都可以用邮件询问。

2.在你的项目中新建一个文件夹用来放置库文件，可以直接将SDK中的库文件一股脑全放进来，我这里就是全放进来的，如图：

3.将java的demo中的examples.jar和jna.jar加载到自己的项目中，将java的demo中HCNetSDK.java 直接复制到自己的项目中，我们就是通过实现这个接口的方法来对设备进行操作。

4.根据sdk手册的信息建立相应的类，接口，回调函数，新建立的这些最好也放到HCNetSDK.java中。

图中红圈表示HCNetSDK.java要去加载HCNetSDK.dll文件

所以需要写一个路径加载类：HCNetSDKPath.java

package com.ykl; import java.io.UnsupportedEncodingException; public class HCNetSDKPath { public static String dllPath;//HCNetSDK.dll 文件路径 public static void main(String[] args) { String path = (HCNetSDKPath.class.getResource("/HCNetSDK/HCNetSDK.dll").getPath()) .replaceAll("%20", " ").substring(1).replace("/","\\"); System.out.println(path); try { dllPath = java.net.URLDecoder.decode(path, "utf-8"); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } System.out.println(dllPath); } }

在自己的类中需要实例化HCNetSDK，具体写法是：HCNetSDK hCNetSDK = HCNetSDK.INSTANCE;

5.接下来写一个工具类，里面有调用设备的基础方法：HCNetDeviceUtil.java

package com.utils; import java.io.ByteArrayInputStream; import java.io.UnsupportedEncodingException; import com.sun.jna.NativeLong; import com.sun.jna.Pointer; import com.ykl.FMSGCallBack_V31; public class HCNetDeviceUtil { HCNetSDK hcNetSDK=HCNetSDK.INSTANCE; HCNetSDK.NET_DVR_USER_LOGIN_INFO m_strLoginInfo = new HCNetSDK.NET_DVR_USER_LOGIN_INFO();//设备登录信息 HCNetSDK.NET_DVR_DEVICEINFO_V40 m_strDeviceInfo = new HCNetSDK.NET_DVR_DEVICEINFO_V40();//设备信息 static FMSGCallBack_V31 fMSFCallBack_V31;//报警回调函数实现类 FRemoteCfgCallBackCardGet fRemoteCfgCallBackCardGet;//获取卡参数回调函数实现类 FRemoteCfgCallBackCardSet fRemoteCfgCallBackCardSet;//下发卡回调函数实现类 FRemoteCfgCallBackFaceGet fRemoteCfgCallBackFaceGet;//获取人脸回调函数实现类 FRemoteCfgCallBackFaceSet fRemoteCfgCallBackFaceSet;//下发人脸回调函数实现类 //登录设备，设备会返回，唯一用户ID：lUserID public String loginDevice(String ip,String port,String userName,String password) { //初始化SDK boolean status = hcNetSDK.NET_DVR_Init(); if(status!=true) { System.out.println("初始化失败："+hcNetSDK.NET_DVR_GetCardLastError_Card()); }else { System.out.println("初始化成功！"); } //设置报警回调函数，这个函数将会上次人脸识别比对结果 if (fMSFCallBack_V31 == null){ fMSFCallBack_V31 = new FMSGCallBack_V31(); Pointer pUser = null; if (!hcNetSDK.NET_DVR_SetDVRMessageCallBack_V31(fMSFCallBack_V31, pUser)){ System.out.println("设置回调函数失败!"); } } //注册 String m_sDeviceIP = ip;//设备ip地址 m_strLoginInfo.sDeviceAddress = new byte[HCNetSDK.NET_DVR_DEV_ADDRESS_MAX_LEN]; System.arraycopy(m_sDeviceIP.getBytes(), 0, m_strLoginInfo.sDeviceAddress, 0, m_sDeviceIP.length()); String m_sUsername = userName;//设备用户名 m_strLoginInfo.sUserName = new byte[HCNetSDK.NET_DVR_LOGIN_USERNAME_MAX_LEN];

int lUserID = hcNetSDK.NET_DVR_Login_V40(m_strLoginInfo, m_strDeviceInfo); if (lUserID == -1) { System.out.println( "注册失败，错误号:" + hcNetSDK.NET_DVR_GetLastError()); //这里自己做错误处理 } return lUserID+""; } //获取卡参数 public void GetCardInfo(int lUserID){ int iErr = 0;

} System.out.println( "断开长连接成功!"); } }

6.接下来还要编写HCNetDeviceUtil类中的定义的几个回调函数实现类

package com.utils; import com.sun.jna.Pointer; //下发卡号，回调函数实现类 public class FRemoteCfgCallBackCardSet implements HCNetSDK.FRemoteConfigCallback{ public void invoke(int dwType, Pointer lpBuffer, int dwBufLen, Pointer pUserData){ System.out.println("长连接回调获取数据,NET_SDK_CALLBACK_TYPE_STATUS:" + dwType); if(dwType==0) { HCNetSDK.REMOTECONFIGSTATUS_CARD struCardStatus = new HCNetSDK.REMOTECONFIGSTATUS_CARD(); struCardStatus.write(); Pointer pInfoV30 = struCardStatus.getPointer(); pInfoV30.write(0, lpBuffer.getByteArray(0, struCardStatus.size()), 0,struCardStatus.size()); struCardStatus.read(); int iStatus = 0; for(int i=0;i
