当我将一个整数传递给方法调用时,我得到java.lang.UnsatisfiedLinkError
。如果我没有传递任何参数,该功能就像魅力一样。
我可能做错了什么?
线程“main”中的异常java.lang.UnsatisfiedLinkError: JniTimer.jniWait(I)V 在JniTimer.main(JniTimer.java:15)
Java代码:
public class JniTimer {
static {
System.loadLibrary("JniTimer.dll");
}
public native void jniWait(int msec);
public static void main(String[] args) {
JniTimer myTimer = new JniTimer();
int a = 100;
myTimer.jniWait(a);
}
}
