TimeStamp Adapters for JAXB

As we have seen in many cases, the Timestamp coming in as Sting, it is easier to cast it using JAXB.

Here is the TimeStampAdapter which we can use it to streamline the same

Just define the TimeStamp attribute of the JAXB Object as date as follows

    @XmlElement(name = "ActionTimestamp")
    @XmlJavaTypeAdapter(TimeStampAdapter.class)
    private Date actionTimestamp;

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

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

public class TimeStampAdapter extends XmlAdapter {
    private SimpleDateFormat firstFormat = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");
    private SimpleDateFormat secondTimeFormat = new SimpleDateFormat("yyyy/MM/dd HH:mm:ss:SSS");

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

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

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;
    }
}

Convert Object to XML String

 public String convertObjectToXmlString(ObjectClass theObjectClass)
   throws Exception {
  Marshaller triggerMarshaller = null;
  System.out.println("Converting String into XML");
  /** Anonymous Inner Class */
  OutputStream output = new OutputStream() {
   private StringBuilder string = new StringBuilder();

   @Override
   public void write(int b) throws IOException {
    this.string.append((char) b);
   }

   @Override
   public String toString() {
    return this.string.toString();
   }
  };

  JAXBContext jc = JAXBContext.newInstance("Your Package Name");
  triggerMarshaller = jc.createMarshaller();
  triggerMarshaller.marshal(triggerMessage, new StreamResult(output));
  return output.toString();

 }
