Easy and handmade serializing for java (influenced from Rails Active Model Serializer)

Event.java

package com.et.models;

import com.et.util.EventGalleryParam;
import com.et.util.airbrake.AirbrakeLogFactory;
import com.et.util.persistence.ORM;
import org.apache.log4j.Logger;

import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.Date;

public class Event extends ORM {
  private static Logger logger	= Logger.getLogger(Event.class.getName(), new AirbrakeLogFactory());

  public long id;
  public long version;
  public boolean activo;
  public String name;
  public long venue_id;
  public String description;
  public String door_policies;
  public long tbl_event_type_id;
  public String time;
  public String slug;
  public Date create_date;

  private Venue venue;

  public Venue getVenue() {
    if(venue == null && venue_id > 0)
      this.venue = Venue.find(this.venue_id);

    return this.venue;
  }
  
  public EventSerializer serialize() {
    return new EventSerializer(this);
  }
}

EventsController.java

package com.et.service;

import com.et.models.Event;
import com.et.util.RequestParam;
import com.et.util.airbrake.AirbrakeLogFactory;
import com.et.util.serializers.web.EventSerializer;
import org.apache.log4j.Logger;

public class EventController {

    private static Logger logger	= Logger.getLogger(EventController.class.getName(), new AirbrakeLogFactory());
    private RequestParam params;

    public EventController(RequestParam requestParam) {
        this.params = requestParam;
    }

    public EventSerializer show() {
        return Event.findBySlug(params.slug).serialize();
    }
}

EventSerializer.java

package com.et.util.serializers.web;

import com.et.models.Event;
import com.et.models.EventType;
import com.et.util.EventGalleryParam;

import java.text.SimpleDateFormat;
import java.util.ArrayList;

public class EventSerializer {
    public Long id      = null;
    public String name  = null;
    public String description   = null;
    public String door_policies = null;
    public String time          = null;
    public String date          = null;
    public EventType event_type = null;
    public VenueShortSerializer venue = null;
    public ArrayList<EventGalleryParam> gallery		= new ArrayList<EventGalleryParam>();

    public EventSerializer(Event event){
        SimpleDateFormat formatter = new SimpleDateFormat("yyyy-MM-dd");
        this.id             = event.id;
        this.name           = event.name;
        this.description    = event.description;
        this.date           = formatter.format(event.create_date);
        this.time           = event.time;
        this.door_policies  = event.door_policies;
        this.gallery        = event.getGallery();
        this.event_type     = event.getType();
        this.venue          = event.getVenue().serialize();
    }
}
