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.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();

if (!hcNetSDK.NET_DVR_SetDVRMessageCallBack_V31(fMSFCallBack_V31, pUser)){

准备工作就到这里为止了，接下来就是具体怎么操作设备了
我将代码从项目提取出来了，开发工具是Eclipse创建的是web项目：
