Now im really lost...or confused...I got this class
package co.com.adv.Salarix2.core.nominaprocessor.model;
// Generated 23/08/2011 03:13:44 PM by Hibernate Tools 3.2.4.GA

@Embeddable
public class NodoId implements java.io.Serializable {
private int idArbol;
private int idNodo;
private int idHoja;
public NodoId() {
}
public NodoId(int idArbol, int idNodo, int idHoja) {
this.idArbol = idArbol;
this.idNodo = idNodo;
this.idHoja = idHoja;
}
@Column(name = "Id_Arbol", nullable = false)
public int getIdArbol() {
return this.idArbol;
}
public void setIdArbol(int idArbol) {
this.idArbol = idArbol;
}
@Column(name = "Id_Nodo", nullable = false)
public int getI开发者_C百科dNodo() {
return this.idNodo;
}
public void setIdNodo(int idNodo) {
this.idNodo = idNodo;
}
@Column(name = "Id_Hoja", nullable = false)
public int getIdHoja() {
return this.idHoja;
}
public void setIdHoja(int idHoja) {
this.idHoja = idHoja;
}
public boolean equals(Object other) {
if ((this == other))
return true;
if ((other == null))
return false;
if (!(other instanceof NodoId))
return false;
NodoId castOther = (NodoId) other;
return (this.getIdArbol() == castOther.getIdArbol())
&& (this.getIdNodo() == castOther.getIdNodo())
&& (this.getIdHoja() == castOther.getIdHoja());
}
public int hashCode() {
int result = 17;
result = 37 * result + this.getIdArbol();
result = 37 * result + this.getIdNodo();
result = 37 * result + this.getIdHoja();
return result;
}
public String getStringRep() {
return this.idArbol + "-" + this.idHoja + "-" + this.idNodo;
}
}
If i keep the last method...
public String getStringRep() {
return this.idArbol + "-" + this.idHoja + "-" + this.idNodo;
}
It throws the maping exception:
DEPLOYMENTS IN ERROR: Deployment "persistence.unit:unitName=Salarix2.ear/Salarix2.jar#Salarix2" is in error due to the following reason(s): org.hibernate.AnnotationException: referencedColumnNames(Id_Arbol, Id_ Nodo, Id_Hoja) of co.com.adv.Salarix2.core.nominaprocessor.model.Nodo.nodo referencing co.com.adv.Salarix2.core.nominaprocessor.model.Nodo not mapped to a single property
but if I remove the method it deployes ok....Why this happen???
This is because Hibernate uses Reflection and considers that Classes are "beans". Beans have a standard nomenclature for getters and setters, if you have a getter like getStringRep, hibernate will try to find a property called StringRep - which you don't have -
To avoid that just use non-standard names for non-persistence properties, for example stringRep()
instead of getStringRep()
(or use @Transient
annotation over getter). That should solve your problem.
