1.步骤

  1.编写dll文件,放入项目的bin目录(在window上是dll文件,在Linux上是so文件,dll和so都是由C程序生成)
   2.新建接口继承Library
   3.加载对应的dll或者so文件:CLibrary INSTANCE =Native.loadLibrary("hz", CLibrary.class);
   4.声明native方法:void HelloWorld();
   5.调用 :CLibrary.INSTANCE.HelloWorld();

2.一个简单实例

import com.sun.jna.Library;
import com.sun.jna.Native;
import com.sun.jna.Platform; public class HelloWord { public interface CLibrary extends Library{
//加载库
CLibrary INSTANCE =Native.loadLibrary("hz", CLibrary.class);
//声明方法
void HelloWorld();
} public static void main(String[] args) {
//调用
CLibrary.INSTANCE.HelloWorld();
}
}
