背景：由于工作问题，最近对接了海康的设备网络SDK，参考了SDK自带demo，还有一部分的网上博客，发现没有很全的，自己决定把自己开发的经验分享下
基本信息：
JDK11
springboot 2.5
官网下载的SDK：CH-HCNetSDKV6.1.6.45_build20210302_win64
对接的设备：人脸识别一体机（明眸设备——卡为中心、人为中心）
代码简介：
hklib是存放win下SDK文件的
custom下是核心代码，五个Service结尾的，分别是明眸卡为中心，明眸人脸为中心，设备登陆，设备订阅，设备SDK初始化，包含了人脸识别一体机基本操作，登陆，订阅，下发卡号，人脸，删除卡号人脸，刷卡刷脸事件上报。
lib目录下为SDK的对接文件，参考jSDK目录中 CH-HCNetSDKV6.1.6.45_build20210302_win64\Demo示例\4- Java 开发示例\4-明眸门禁优化接口(以人为中心)\Test1\src\Test1 部分修改
SDK继承：StdCallLibrary改成 Libray，StdCallLibaray是win下使用，改过之后可以win、linux通用
public interface HCNetSDK extends LibraryDemo中win32的都是只能win下使用，由于本人没有引入example.jar 所以直接删除了相关内容（主要涉及视屏流），我对接的设备不需要使用。
SDK加载方式修改：
HCNetSDK INSTANCE = Native.load(OSUtils.getLoadLibrary(), HCNetSDK.class);内部类代码全部继承：SdkStructure，重写一个getFiledOrder来解决空指针问题（不知道是不是只有我遇到的）
public static class SdkStructure extends Structure {
@Override
protected List<String> getFieldOrder(){
List<String> fieldOrderList = new ArrayList<String>();
for (Class<?> cls = getClass();
!cls.equals(SdkStructure.class);
cls = cls.getSuperclass()) {
Field[] fields = cls.getDeclaredFields();
int modifiers;
for (Field field : fields) {
modifiers = field.getModifiers();
if (Modifier.isStatic(modifiers) || !Modifier.isPublic(modifiers)) {
continue;
}
fieldOrderList.add(field.getName());
}
}
return fieldOrderList;
}
}/**
* 获取库文件
* 区分win、linux
* @return
*/
public static String getLoadLibrary() {
if (isChecking()) {
return null;
}
String loadLibrary = "";
String library = "";
String osPrefix = getOsPrefix();
if(osPrefix.toLowerCase().startsWith("win32-x86")) {
loadLibrary = System.getProperty("user.dir") + File.separator+ "hklib" + File.separator;
library = "HCNetSDK.dll";
} else if(osPrefix.toLowerCase().startsWith("win32-amd64") ) {
loadLibrary = System.getProperty("user.dir") + File.separator+ "hklib" + File.separator;

library = "";

m_strLoginInfo.wPort = Short.valueOf("8000");
m_strLoginInfo.bUseAsynLogin = false; //是否异步登录：0- 否，1- 是
m_strLoginInfo.write();
HCNetSDK.NET_DVR_DEVICEINFO_V40 m_strDeviceInfo = new HCNetSDK.NET_DVR_DEVICEINFO_V40();//设备信息
int loginHandler = hCNetSDK.NET_DVR_Login_V40(m_strLoginInfo, m_strDeviceInfo);
if (loginHandler == -1) {
int errorCode = hCNetSDK.NET_DVR_GetLastError();
IntByReference errorInt = new IntByReference(errorCode);
log.error("[HK] login fail errorCode:{}, errMsg:{}", errorCode, hCNetSDK.NET_DVR_GetErrorMsg(errorInt));
return hCNetSDK.NET_DVR_GetErrorMsg(errorInt);
} else {
loginHandleMap.put(m_sDeviceIP,loginHandler);
int iCharEncodeType = m_strDeviceInfo.byCharEncodeType;
encodeMap.put(loginHandler,iCharEncodeType);
log.info("[HK] login success iCharEncodeType:{}", iCharEncodeType);
log.info("[HK] login map:{}", loginHandleMap);
return "success";
