Date and Time Adapter for JAXB

It is often very time consuming to check for the incoming String and cast it using SimpleDateFormat in every class. Here is a simple way to fasten this by using Date Adapters in JAXB itself.

All you need to do is to define the JAXB objects to be Date as follows

@XmlElement(name = "CreditValueDate")
    @XmlJavaTypeAdapter(DateTypeAdapter.class)
    private Date creditValueDate;
    @XmlElement(name = "DebitValueDate")
    @XmlJavaTypeAdapter(DateTypeAdapter.class)
    private Date debitValueDate;

Class for DateTypeAdapters

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

import javax.xml.bind.annotation.adapters.XmlAdapter;

public class DateTypeAdapter extends XmlAdapter {
    private SimpleDateFormat firstDateFormat = new SimpleDateFormat("yyyy-MM-dd");
    private SimpleDateFormat secondDateFormat = new SimpleDateFormat("yyyy/MM/dd");

    @Override
    public String marshal(Date v) {
 return secondDateFormat.format(v);
    }

    @Override
    public Date unmarshal(String v) throws ParseException {
 Date returnDate = null;
 try {
     returnDate = firstDateFormat.parse(v);
 } catch (Exception prse) {
     returnDate = secondDateFormat.parse(v);
 }
 return returnDate;
    }
}
