使用jna-4.4.0.jar
访问Windows 7 Native库时，我的异常低于Exception添加-Djna.debug_load=true -Djna.debug_load.jna=true参数后，我的输出低于UnsatisfiedLinkError。

并且，我正在尝试使用以下代码加载Windows库来设置壁纸。
public static interface User32 extends Library{
User32 INSTANCE = (User32) Native.loadLibrary("win64", User32.class, W32APIOptions.DEFAULT_OPTIONS);
boolean SystemParametersInfo(int one, int two, String s, int three);
}
现在，我无法找到win32-x86-64 / win64.dll的库路径。它所在的位置和路径是什么？
