Java調用第三方dll文件的使用方法

 

public class OtherAdapter {
static
    { 
        //System.loadLibrary("Connector");//載入需要調用的dll  Connector.dll
		System.load("d://Connector.dll");//載入dll  Connector.dll
    }

    //用native關鍵字修飾將被其它語言實現的方法
	//dll文件中對應的函數聲明
   	public native static int _PWLogon(String lpszDS,String lpszUser,String lpszPWD);
	//函數聲明
   	public native static void _PWLogout();
	public native static String _GetPWLastError();
	public native static String _GetPWFolders(long lParentFolderno);
	public native static String _GetPWDocuments(long lFolderno);
	public native static String _GetPWFiles(long lFolderno,long lDocno);
		
   //public native static String pirntStr(String msg);//函數聲明
   public static void main(String[] args){
        //本地方法的調用
        int rs=_PWLogon("服務器","賬號","密碼");
        System.out.println("用戶登錄狀態："+rs);
				if(rs==1)
				{
					System.out.println("獲取頂級目錄："+_GetPWFolders(0));
					
					System.out.println("獲取父子目錄："+_GetPWDocuments(54));
					
					System.out.println("下載指定文件："+_GetPWFiles(54,2));
					
					_PWLogout();
				}
				else
				{
					System.out.println("獲取錯誤信息："+_GetPWLastError());
				}
    }
