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;
}

看看这段代码:-

/* Create Date Object */
Date date = new Date();
XMLGregorianCalendar xmlDate = null;
GregorianCalendar gc = new GregorianCalendar();

gc.setTime(date);

try{
    xmlDate = DatatypeFactory.newInstance().newXMLGregorianCalendar(gc);
}
catch(Exception e){
    e.printStackTrace();
}

System.out.println("XMLGregorianCalendar :- " + xmlDate);

你可以在这里看到完整的例子

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();

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);
   }

}

使用Joda-Time库的一行示例:

XMLGregorianCalendar xgc = DatatypeFactory.newInstance().newXMLGregorianCalendar(new DateTime().toGregorianCalendar());

这要归功于Nicolas Mommaerts在公认答案中的评论。

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;
