一、海康威視NVR SDK下載
SDK下載地址
根據你的設備或者運行環境選擇相應的版本（文章用的是win64版）
二、引入海康SDK
1.將海康提供的jar包匯入到本地Maven庫
【傳送門】匯入步驟
百度網盤Maven匯入JAR
提取碼：q4w3
Maven匯入方式
<!-- 海康JNA jar包 -->
<dependency>
<groupId>com.sun.jna</groupId>
<artifactId>jna</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<!-- 海康examples jar包 -->
<dependency>
<groupId>com.sun.jna.examples</groupId>
<artifactId>examples</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
2.將SDK放在專案中
將DLL檔案庫放到靜態資源目錄下，一面打JAR包時找不到檔案庫
3.組態檔讀取
獲取靜態資源檔案夾路徑
public class CommonKit {
/**
* 獲取DLL檔案路徑
* @return
*/
public static String getWebPath(){
String path = CommonKit.class.getClassLoader().getResource("").getPath().substring(1);
return path+"dll\\";
}
}
修改SDK中DLL庫讀取
public interface HCNetSDK extends StdCallLibrary {
/*加載海康DLL*/
HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary(CommonKit.getWebPath()+"HCNetSDK.dll", HCNetSDK.class);
}
同理PlayCtrl也一樣
public interface PlayCtrl extends StdCallLibrary {
/*加載播放DLL*/
PlayCtrl INSTANCE = (PlayCtrl) Native.loadLibrary(CommonKit.getWebPath()+"PlayCtrl.dll", PlayCtrl.class);
}
三、寫常用的介面
3.1根據時間獲取檔案
