Hibernate request example (from Spring 3)

Question

I created entity classes Adress, Roadand County. A Roadis in Countyand a Adressin on a Road. I would like to list everything Adressesin County. Therefore, in my AdressServiceI say:

public List<Adress> AllAdresses(County county) {
  Adress adress = new Adress();
  Road road = new Road();
  road.setCounty(county);
  adress.setRoad(road);

  Example example = Example.create(adress);
  return (List<Adress>) adressDAO.query(Adress.class, example);
}

In mine AdressDAO, I have query ():

public List query(Class<?> c, Example example) {
  return getSession().createCriteria(c).add(example).setMaxResults(100).list();
}

Executes the following query on my database server:

select this_.AdressId as AdressId2_0_, 
       this_.Description as Descript3_2_0_, 
       this_.DescriptionShort as Descript4_2_0_, 
       this_.HouseLetter as HouseLetter2_0_, 
       this_.HouseNr as HouseNr2_0_, 
       this_.RoadId as RoadId2_0_ 
from tblAdress this_ 
where (this_.HouseNr=0) 
limit 100

I expected him to at least include some information about my essence Countyand inner connection with tblRoad. tblRoadhas a primary key roadId, so I expected to this_.roadIdbe connected to tblRoad.roadId, and I expected to tblRoad.countyIdbe installed in the primary key County, that is countyId.
