JAVA 調用dll

package com.safein.main;

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

public class Test {

   public interface CLibrary extends Library{  
          //接口執行個體  
          CLibrary INSTANCE = (CLibrary)Native.loadLibrary("cbtest.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");  
           // 首先定義指針，開辟記憶體空間，這裡的記憶體空間根據傳回的字元串來決定  
//           Pointer p = new Memory(1024) ;

//               System.out.print((char) p.getByteArray(0, 11)[i]);  
//           }  
//           System.out.println("\n");
