I have a function that simply gets a location by id:
public Location getLocationById(Long idSearchedLocation){
Session session = HibernateUtil.getSessionFactory().getCurrentSession();
session.beginTransaction();
Location location = null;
try{
location = (Location) session.load(Location.class, idSearchedLocation);
//System.out.println(location.getLat() + " " +this.getClass().getName());
} catch (HibernateException e) {
e.printStackTrace();
session.getTransaction().rollback();
}catch(Exception e){
e.printStackTrace();
}
session.getTransaction().commit();
return location;
}
In another function I get the location object and I try to access the location fields:
Location location = mainManager.getLocationById(idSearchedLocation);
System.out.println(location.getLat() + " " +this.getClass().getName());
And then I get the exception after I receive the returned location, when I try to print location.getLat():
org.hibernate.LazyInitializationException: could not initialize proxy - no Session
It is weird why I get this error because the Location object does neighter have collections nor associated entities: just String and Float types.
If I uncomment the line that prints location.getLat() in the dao function, all is working as expected, it loads everything (no exception, and the print succeeds). But why is Hibernate not loading the fields of the object in the first case?
UPDATE
@Entity
@Table(name="location")
public class Location {
private Long id;
private String name;
private String country;
private String address;
private Float lat;
private Float lng;
//getters and setters
}
