package com.safein.main;

import com.sun.jna.Library;
import com.sun.jna.Native;

public class Test {

 public interface CLibrary extends Library{  
        //接口实例  
        CLibrary INSTANCE = (CLibrary)Native.loadLibrary("cbtest.dll",CLibrary.class);  
//        CLibrary INSTANCE = (CLibrary)Native.loadLibrary("dllTest.dll",CLibrary.class);  
//        CLibrary INSTANCE = (CLibrary)Native.loadLibrary("Win32ProjectTest.dll",CLibrary.class);  
  
//        int add(int a,int b);  
        String hello();
    }  
  

    public static void main(String[] args) {  
    
//    System.setProperty("jna.encoding", "GBK");  
         // 首先定义指针，开辟内存空间，这里的内存空间根据返回的字符串来决定  
//         Pointer p = new Memory(1024) ;  
           
//         System.out.println(CLibrary.INSTANCE.add(1,2));
    System.out.println(CLibrary.INSTANCE.hello());;
//    CLibrary.INSTANCE.hello();
    
//         for(int i=0, sumi=11; i< sumi; i++){  
//             System.out.print((char) p.getByteArray(0, 11)[i]);  
//         }  
//         System.out.println("\n");  
    }  
}

用到了一个jar jna-4.0.0.jar 经测试一切正常
