Entity and set/get methods

[Mihai Radulescu]

Hi

I have a Entity which has a non-transitive property, for this property I have no set/get. If I persist this in the database I get the value for the field with no geter. That means, the entity manager does not care of setter or getter, it just "grab" the value .
the next code snippet show the entity :

@Entity
class MyWrongEntity {

private int id;

private int stuff = 10;


public void setId() {
}

@Id
public int getId() {
}

}

After this entity is persisted in the db I have for the stuff variable the value 10. Strange because I don't have a get for.

My question is : why is doing the the jpa container this ? Is this specified in the specifications ?

Because you did put the id annotation on the getter the persistence provider assumes you want to use property based persistence.

Thanks for your answer

I already spot this i the specification (2.2 Persistent Fields and Properties)

The persistent state of an entity is accessed by the persistence provider runtime[1] either via JavaBeans style property accessors (“property access”) or via instance variables (“field access”). Whether persistent properties or persistent fields or a combination of the two is used for the provider’s access to a given class or entity hierarchy is determined as described in Section 2.3, “Access Type”.
