海康抓拍机抓拍图片

1.下载官方sdk包,分清版本 

https://open.hikvision.com/download/5cda567cf47ae80dd41a54b3?type=10

2.把dll等库文件放入到项目目录中,

　把examples.jar ,  jna.jar放入同服务下resources下的lib目录中,通过pom文件读取

 3.官方sdk的不同demo中,HCNetSDK文件,拥有的函数类是不同的,如果你的HCNetSDK文件中查不到文档中的函数,可以换个demo查找.

    由于我集成了两个demo,为了方便,抓拍的HCNetSDK文件名修改为 ArmedHCNetSDK.

4.HCNetSDK要加载HCNetSDK.dll 库文件,不知道为什么,使用相对路径一直报错,索性使用绝对路径,播放库同理

5.前期准备完成,下面是抓拍代码,其中ip,username,pwd 用实体类存放,方便传入,大家测试时可以暂时写死,拍照的路径也可自主定义,一般在此报警信息中  COMM_ITS_PLATE_RESULT
