GregorianCalendar c = new GregorianCalendar();
c.setTime(yourDate);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

GregorianCalendar c = new GregorianCalendar();
c.setTime(yourDate);
XMLGregorianCalendar date2 = DatatypeFactory.newInstance().newXMLGregorianCalendar(c);

下面是一个从GregorianCalendar转换为XMLGregorianCalendar的方法;我将把从java.util.Date转换为GregorianCalendar的部分留给您作为练习:

import java.util.GregorianCalendar;

import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class DateTest {

   public static void main(final String[] args) throws Exception {
      GregorianCalendar gcal = new GregorianCalendar();
      XMLGregorianCalendar xgcal = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gcal);
      System.out.println(xgcal);
   }

}

编辑:Slooow:-)

我希望我的编码是正确的，D 为了使它更快，只需使用丑陋的getInstance()调用GregorianCalendar而不是构造函数调用:

import java.util.GregorianCalendar;
import javax.xml.datatype.DatatypeFactory;
import javax.xml.datatype.XMLGregorianCalendar;

public class DateTest {

   public static void main(final String[] args) throws Exception {
      // do not forget the type cast :/
      GregorianCalendar gcal = (GregorianCalendar) GregorianCalendar.getInstance();
      XMLGregorianCalendar xgcal = DatatypeFactory.newInstance()
            .newXMLGregorianCalendar(gcal);
      System.out.println(xgcal);
   }

}

我的解决方案

public static XMLGregorianCalendar DateToXMLGregorianCalendar(Date date) {

    GregorianCalendar gregoriancalendar = new GregorianCalendar();
    gregoriancalendar.setTime(date);
    XMLGregorianCalendar xmlGregorianCalendar = new XMLGregorianCalendarImpl(gregoriancalendar);
    return xmlGregorianCalendar;
}

对于那些可能在这里结束寻找相反转换(从XMLGregorianCalendar到Date)的人:

XMLGregorianCalendar xcal = <assume this is initialized>;
java.util.Date dt = xcal.toGregorianCalendar().getTime();
