您可以通过date对象本身来实现：
String formattedDate = sdf.format(categoryData.getBulkCollectionTime()); //yyyy-MM-dd HH:mm:ssconvertStringToXmlGregorian(formattedDate);public XMLGregorianCalendar convertStringToXmlGregorian(String dateString){ try { Date date = sdf.parse(dateString); GregorianCalendar gc = (GregorianCalendar) GregorianCalendar.getInstance(); gc.setTime(date); return DatatypeFactory.newInstance().newXMLGregorianCalendar(gc); } catch (ParseException e) { // Optimize exception handling System.out.print(e.getMessage()); return null; }}
