我一直在尝试将d-logic ufr系列rfid阅读器与java集成。我使用了他们的资料库中提供的示例应用程序https://www.d-logic.net/code/nfc-rfid-reader-sdk/ufr-mf-examples-java 但是当我运行应用程序时，我得到如下错误-

java.lang.UnsatisfiedLinkError: Unable to load library 'C:\Users\Downloads\ufr-mf-examples-java-master\ufr-mf-examples-java-master\uFCoderSimple\ufr-lib\windows\x86_64\uFCoder-x86_64.dll': Native library (win32-x86-64/C:\Users\Downloads\ufr-mf-examples-java-master\ufr-mf-examples-java-master\uFCoderSimple\ufr-lib\windows\x86_64\uFCoder-x86_64.dll) not found in resource path ([target classes])

我已经检查了dll文件存在的路径，它们是可用的。我试过用其他一些dll，不管程序是否正在访问dll文件，然后我发现它正在访问，但当我提供ufcoder-x86\u 64.dll路径时，它给出了这个错误，请任何人帮助
操作系统-windows 10 64位oracle jdk-1.8 netbeans ide

try {

            uFrINSTANCE = (uFrFunctions) Native.loadLibrary("dll path", uFrFunctions.class);
        } catch (UnsatisfiedLinkError e) {
            e.printStackTrace();
            JOptionPane.showMessageDialog(null, "Unable to load library for path : " + GetLibFullPath(false));
        }
