1.下載官方sdk包,分清版本
https://open.hikvision.com/download/5cda567cf47ae80dd41a54b3?type=10
2.把dll等庫文件放入到項目目錄中,
把examples.jar , jna.jar放入同服務下resources下的lib目錄中,通過pom文件讀取
3.官方sdk的不同demo中,HCNetSDK文件,擁有的函數類是不同的,如果你的HCNetSDK文件中查不到文檔中的函數,可以換個demo查找.
由於我集成了兩個demo,為了方便,抓拍的HCNetSDK文件名修改為 ArmedHCNetSDK.
4.HCNetSDK要加載HCNetSDK.dll 庫文件,不知道為什么,使用相對路徑一直報錯,索性使用絕對路徑,播放庫同理
5.前期准備完成,下面是抓拍代碼,其中ip,username,pwd 用實體類存放,方便傳入,大家測試時可以暫時寫死,拍照的路徑也可自主定義,一般在此報警信息中 COMM_ITS_PLATE_RESULT
