java.util.Date转javax.xml.datatype.XMLGregorianCalendar

对于[webservice][6]应用时需要java.util.Date转javax.xml.datatype.XMLGregorianCalendar方法如下：

public static XMLGregorianCalendar convertToXMLGregorianCalendar(Date date) {        GregorianCalendar cal = new GregorianCalendar();        cal.setTime(date);        XMLGregorianCalendar gc = null;        try {            gc = DatatypeFactory.newInstance().newXMLGregorianCalendar(cal);        } catch (Exception e) {            e.printStackTrace();        }        return gc;    }
