Smbfile获取java中的上次访问日期

我正在使用共享文件。我正在使用jcifs.jar库获取共享文件的列表

NtlmPasswordAuthentication authentication = new NtlmPasswordAuthentication(host, username, password);
SmbFile rootFile = new SmbFile(fullPath, authentication);
SmbFile[]  listFiles = root.listFiles();

for (int i = 0, i< listFiles.length;  i++) {
 SmbFile sf = listFiles[i];
 //I need to get last accessed date of each sf file.
}

没有用于检查上次访问的嵌入方法。最近的方法是最后修改的：

 getDate
 public long getDate()
 This URLConnection method just returns the result of lastModified.
 Overrides:
 getDate in class java.net.URLConnection
 Returns:
 the last modified data as milliseconds since Jan 1, 1970

你可以看看谷歌添加了这个功能的版本

 getDate
 public long getDate()
 This URLConnection method just returns the result of lastModified.
 Overrides:
 getDate in class java.net.URLConnection
 Returns:
 the last modified data as milliseconds since Jan 1, 1970
