在调试海康威视win64位java版本demo时根据文档提示发现还是报错

这里写内容说明的意思其实是要把整个库文件都拷贝进去才对，然后把HCNetSDK.java中加载dll文件的路径改成自己的文件路径，就可以了。

或者

SDK文件夹是我自己存放库文件的位置

获取文件路径代码，参考自某一网友并作了些改变优化，其中SDK是你自己放库文件的文件夹

import java.io.File;
import java.io.UnsupportedEncodingException;

public class HCNetSDKPath {

  public static String DLL_PATH;
  static {
	  String path = (HCNetSDKPath.class.getResource("/").getPath()).
        replaceAll("%20", " ").substring(1).replace("bin", "SDK").replace("/","\\");
	  System.out.println(path);
    try {
      DLL_PATH = java.net.URLDecoder.decode(path, "utf-8");
    } catch (UnsupportedEncodingException e) {
      e.printStackTrace();
    }
  }
}

HCNetSDK.java中

将

HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary....

改为

HCNetSDK INSTANCE = (HCNetSDK) Native.loadLibrary(HCNetSDKPath.DLL_PATH +"HCNetSDK.dll",
            HCNetSDK.class);

将

PlayCtrl INSTANCE = (PlayCtrl) Native.loadLibrary...

改为

PlayCtrl INSTANCE = (PlayCtrl) Native.loadLibrary(HCNetSDKPath.DLL_PATH+"PlayCtrl.dll",PlayCtrl.class);
