前言
本来一个很简单的SDK接口对接，折腾了好久；总结下原因有：
海康的SDK底层使用C++写的，我不熟悉C++；
海康Java源码示例写的是一个Swing桌面应用，我需要的是嵌入到web项目；
海康《设备网络SDK使用手册》中的示例是用C++写的；并且会出现使用手册和Java源码示例版本不匹配的情况（用手册版本高于Java源码示例版）
我的需求
使用海康认证对面设备在刷身份证和人脸识别通过后，取到身份证信息和人脸照片并且传到页面上。
代码处理
1.将SDK开发包【库文件】里的HCNetSDK.dll、HCCore.dll、PlayCtrl.dll、SuperRender.dll、AudioRender.dll、HCNetSDKCom文件夹、ssleay32.dll、libeay32.dll文件均要加载到程序里面，【HCNetSDKCom文件夹】（包含里面的功能组件dll库文件）需要和HCNetSDK.dll、HCCore.dll一起加载，放在同一个目录下(我的事springboot项目，放在resources目录下)，且HCNetSDKCom文件夹名不能修改。
2.HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary(“E:\project\renliantext\src\main\resources\lib\HCNetSDK”, HCNetSDK.class);修改HCnetSDK的引入路径。
3.将路径：将Demo示例\4- Java 开发示例\2-报警布防监听\AlarmJavaDemo\src\alarmjavademo的demo包移植过来并且解决报错信息，就是导入包的问题 手动引入jar包或者从MAVEN再导入就好
4，写Service类，调用接口进行注册，布防。布防成功后设置报警回调函数
5，写serviceimp类，就是报警回调函数的实现在里面取到想要的数据。
下面是代码
Service类源码 里面有main方法 可以先进行测试看时候可以注册成功已经设置回到函数成功

以上就是全部的代码里 里面有我的项目里的一些实体类可以忽略不计。改成你自己的就好了 遇到问题的小伙伴可以看下 提供一个思路 ，毕竟对接的时候我也是一脸懵逼 研究了一段时间看到别人写的一些东西才调通设备，希望能给其他人一些帮助~~就这吧 加油了嘿嘿 = =
