Может кто-нибудь помочь, я хочу знать, как удалить все компоненты DAYLIGHT и STANDARD из VTIMEZONE, кроме самого последнего в java, когда я добавляю компонент VTimeZone в Календарь, я получаю НЕСКОЛЬКО RDate записей, что просто мусор, поскольку я должен хранить эту строку iCal в дБ
final Calendar calendar = new Calendar();
calendar.getProperties().add(new ProdId(Constants.ICAL_DEFAULT_PROD_ID));
calendar.getProperties().add(Version.VERSION_2_0);
// Create a TimeZone
TimeZoneRegistry registry = TimeZoneRegistryFactory.getInstance().createRegistry();
TimeZone timezone = registry.getTimeZone("America/Vancouver");
VTimeZone tz = timezone.getVTimeZone();
calendar.getComponents().add(tz); // This is causing multiple DAYLIGHT,STANDARD and RDATE garbage,
final VEvent vEvent = new VEvent();
vEvent.getProperties().add(new Uid(DUMMY_UID));
vEvent.getProperties().add(new Summary(Constants.ICAL_DEFAULT_SUMMARY));
vEvent.getProperties().add(new Description(Constants.ICAL_DEFAULT_DESCRIPTION));
final DtStart dtStart = new DtStart(eventStart);
vEvent.getProperties().add(dtStart);
vEvent.getProperties().add(timezone.getVTimeZone().getTimeZoneId());
final DtEnd dtEnd = new DtEnd(eventEnd);
vEvent.getProperties().add(dtEnd);
vEvent.getProperties().add(timezone.getVTimeZone().getTimeZoneId());
Recur recur = null;
final String recurrenceExpression = createRecurrenceExpression(recurrence);
if (!StringUtils.isBlank(recurrenceExpression)) {
try {
recur = new Recur(recurrenceExpression);
final RRule rule = new RRule(recur);
vEvent.getProperties().add(rule);
} catch (Exception e) {
errorMessage = "Exception occurred while creating Recurrence with expression: " + recurrenceExpression + ". Exception: " + e;
LOG.error(errorMessage);
throw new DataException(errorMessage);
}
}
calendar.getComponents().add(event);
Вывод:
