Question

我在写一个小型Java应用程序。我读出了几个Active Directoy用户属性。其中一个属性是lastLogonTimestamp。

//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");


               }
          }

但我无法弄清楚，我如何将属性lastLogonTimestamp转换为String或其他东西，以便我可以使用它。函数.toString不起作用。当我尝试时，我收到错误消息：

有人可以帮帮我吗？为什么属性.toString（）不起作用。如果它可以工作，我可以解析它，然后将其转换为DateTime。需要帮助。

Answer 1

要将Win32文件时字符串转换为Date，请使用：

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

要将Date转换为Win32文件时间，请使用：

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

e.g。 131220409910000000将转换为2016/10/27 14-23-11，反之亦然

您可以使用JNA平台将其转换为Java Date。 lastLogonTimeStamp属性包含Windows FILETIME格式化的值，该值定义为自1601年1月1日午夜以来100纳秒间隔的数量。以下是将日期转换为Windows FILETIME并再次返回的示例。

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);
  }
}
