java - Scala 日期格式问题

Question

我有代码片段，它在 scala 和 java 中提供不同的输出。我想要与 Java 中相同的输出，请任何人指导。

Java 输出:2012-12-13T10:36:38
Scala 中的输出:2012-12-13T10:35:38.000+04:00

/**
 * Convert the datetime to XMLGregorianCalendar datetime format.
 * <br><h6>Example Date format You have to Give is : </h6>
 * new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(Calendar.getInstance().getTime())) 
 * <br>1900-01-01T00:00:00
 */
public static XMLGregorianCalendar stringToXMLGregorianCalendar(String datetime) throws Exception {

    try {
        if(datetime == null || "".equals(datetime))
            return null;
        GregorianCalendar gc = (GregorianCalendar) GregorianCalendar.getInstance();
        gc.setTime(new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").parse(datetime));
        return DatatypeFactory.newInstance().newXMLGregorianCalendar(gc);
    } catch (DatatypeConfigurationException e) {
        logger.error(e.fillInStackTrace());
        throw new Exception(e.fillInStackTrace());
    }
}

也许您应该更改时区

val d = new java.text.SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").format(java.util.Calendar.getInstance().getTime())
val gc: java.util.GregorianCalendar = classOf[java.util.GregorianCalendar].newInstance().asInstanceOf[java.util.GregorianCalendar];     gc.setTime(new java.text.SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss").parse(d));
gc.getTime
gc.getTimeZone

结果:

res6: java.util.Date = Thu Dec 13 17:21:50 GMT+02:00 2012
res7: java.util.TimeZone = sun.util.calendar.ZoneInfo[id="GMT+02:00",offset=7200000,dstSavings=0,useDaylight=false,transitions=0,lastRule=null]
