Answer 1

（1）尝试以下方法：

1. 将两个窗口（64/32位）DLL（如果愿意，也可以）放入一个zip文件中，然后将该文件重命名为。jar。
2. 将该文件添加到应用程序类路径中。
3. 现在，如果您的dll名为“vixallproductsdyn.dll”，则按如下方式调用loadLibrary：native.loadLibrary（“vixallproductsdyn”,“vixallproductsdyn.class”）；

（2）其次，是否尝试这样设置路径:java-djava.library.path=c:\yourlocation VixAllProductsDyn

更新：

你能分享你的代码吗？它应该如下所示：

VixAllProductsDyn lib = (VixAllProductsDyn) Native.loadLibrary("VixAllProductsDyn", VixAllProductsDyn.class);

vixAllProductSdyn.java是一个接口，包含您想要使用的所有方法：

public interface VixAllProductsDyn extends Library {

    public abstract NativeLong OneOfTheMethodsYouWantToCall();
    ...
}
