I am trying to add new trip and place into database. There is relation between them many-to-one, so that one place can be assigned into many places. Place is adding correctly, but during adding trip there is this exception... I know there has been a lot similiar topics, but none of them helped me solving this problem.

public Place getPlace() {
return place;
}
/**

*/
public void setPlace(Place place) {
this.place = place;
}
And other get/set methods...
Place class:
public class Place {
private int idPlace;
private String country;
private String city;
private String island;
private String information;
public Place() {
}
public Place(String country, String city, String island, String information) {
this.country = country;
this.city = city;
this.island = island;
this.information = information;
}
/**
* @return the idPlace
*/
public int getIdPlace() {
return idPlace;
}
/**
* @param idPlace the idPlace to set
*/
public void setIdPlace(int idPlace) {
this.idPlace = idPlace;
}
EDIT1 Adding proper entities is working for me now, but I am wondering is there any way to avoid redundant data? For example, I add a trip and a place X connected with this trip. When I add another trip, but in this same place - X, this place is added again into my database. How can I avoid such action?
ERROR: HHH000122: IllegalArgumentException in class: pl.th.java.biuro.hibernate.Place, getter method of property: idPlace
I think you got this on insert operation. The preceding mean is that, you are inserting illegal argument to idPlace
column. Your were using many-to-one
with pl.th.java.biuro.hibernate.Place
and insert an int
as pl.th.java.biuro.hibernate.Place
. You must change idPlace
type from int
to pl.th.java.biuro.hibernate.Place
.
I hope this will help you.
您应该修改int idPlace int到对象的旅程pl.th.java.biuro.hibernate.Place
