Spring + jaxb app.

In essence, there is a Date field.

@XmlElement(name = "TimeCalc") @XmlJavaTypeAdapter(DateAdapter.class) Date TimeCalc;

How to write jaxb adapter for date data type?

I have a draft, but not a working one:

 public class DateAdapter extends XmlAdapter<String, Date> { private final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-ddTHH:mm:ss:SSS"); @Override public String marshal(Date v) throws Exception { synchronized (dateFormat) { return dateFormat.format(v); } } @Override public Date unmarshal(String v) throws Exception { synchronized (dateFormat) { return dateFormat.parse(v); } } }

In variable I try to parse and fold

 <TimeCalc>20181016T082849.000 GMT</TimeCalc>

    do not ignore TimeZone

     SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd'T'HHmmss.SSS z");

      The working version is the pattern:

       private final SimpleDateFormat dateFormat = new SimpleDateFormat("yyyyMMdd'T'HHmmss.SSS 'GMT'");
