Java Ldap將lastLogonTimestamp轉換爲DateTime

我正在寫一個小型Java應用程序。我讀出了幾個Active Directoy用戶屬性。其中一個屬性是lastLogonTimestamp。Java Ldap將lastLogonTimestamp轉換爲DateTime

//Specify the attributes to return 
      String returnedAtts[]={"accountExpires","lastLogonTimestamp"}; 
      searchCtls.setReturningAttributes(returnedAtts); 

      //Search for objects using the filter 
      NamingEnumeration answer = ctx.search(searchBase, searchFilter, searchCtls); 

      //Loop through the search results 
      while (answer.hasMoreElements()) { 
       SearchResult sr = (SearchResult)answer.next(); 

       System.out.println(">>>" + sr.getName()); 

       //Print out the groups 

       Attributes attrs = sr.getAttributes(); 
       if (attrs != null) { 
        String accountExpires = attrs.get("accountExpires").toString(); 
        Attribute lastLogon = attrs.get("lastLogonTimestamp"); 


       } 
      }

但我不能弄清楚，我如何將屬性lastLogonTimestamp轉換爲字符串或其他東西，所以我可以使用它。函數.toString不起作用。當我嘗試我得到錯誤消息：

有人可以幫我嗎？爲什麼Attribute .toString（）不起作用。如果它能工作，我可以解析它，然後將它轉換爲DateTime。需要幫助。

您可以使用JNA平臺將其轉換爲Java日期。 lastLogonTimeStamp屬性包含一個Windows FILETIME格式化值，該值被定義爲1601年1月1日午夜以來的100納秒間隔數。以下是將日期轉換爲Windows FILETIME並再次轉換的示例。

import java.util.Date; 
import com.sun.jna.platform.win32.WinBase.FILETIME; 

public class WinFileTimeTest { 

    public static void main(String[] args) { 
    Date d1 = new Date(); 

    long wft = FILETIME.dateToFileTime(d1); 

    int l_int = (int)wft; 
    int u_int = (int)(wft >>> 32); 

    Date d2 = FILETIME.filetimeToDate(u_int , l_int); 

    System.out.println("Java Date"); 
    System.out.println(d1); 
    System.out.println("--------------"); 

    System.out.println("Java Date Converted to Windows FILETIME using FILETIME class"); 
    System.out.println(wft); 
    System.out.println("--------------"); 

    System.out.println("Windows FILETIME converted back to Java Date using FILETIME class"); 
    System.out.println(d2); 
    } 
}

爲Win32 FILETIME字符串轉換爲日期，使用方法：

long fileTime = (Long.parseLong(inputDateString)/10000L) - + 11644473600000L; 
Date inputDate = new Date(fileTime);

要轉換日期的Win32 FILETIME，用途：

long fileTime = (inputDate.getTime() + 11644473600000L) * 10000L; 
String outputDate = Long.toString(fileTime);

例如 131220409910000000將被轉換爲2016/10/27 14-23-11，反之亦然
