将转换符合ISO8601的日期与Java日期进行比较？

Question

As per this question , I have found how to parse the Solr date, but I am still unable to compare it with Java date.

DateTimeFormatter parser2 = ISODateTimeFormat.dateTimeNoMillis();
    String jtdate = "2010-01-01T12:00:00+01:00";
    System.out.println(parser2.parseDateTime(jtdate));

Currently I have got date in this format : 2013-07-28T13:48:02Z and I need to apply compareTo() operator on this date with current date from Java.

Answer 1

Assuming you do not care about the time, consider using DateTimeComparator.getDateOnlyInstance() , which is a Comparator that ignores the time fields when making the comparison, eg:

final DateTime a = parser2.parseDateTime(jtdate);
final Date b = new Date();

DateTimeComparator comparator = DateTimeComparator.getDateOnlyInstance();
comparator.compare(a, b);

Or,

comparator.compare(a, DateTime.now());
