Hi, I have two beans
@Entity(access=AccessType.FIELD)
public class BeanNameB implements Serializable {
@Id(generate = GeneratorType.AUTO)
private int id;
private long creationtime;
@PrePersist
public void prePersist() {
this.creationtime = System.currentTimeMillis();
System.out.println("BeanNameB.prePersist");
}
}
@Entity(access=AccessType.FIELD)
public class BeanNameA implements Serializable{
@Id(generate = GeneratorType.AUTO)
private int id;
private long creationtime;
@OneToOne(cascade = CascadeType.ALL)
private BeanNameB beanNameB;
public BeanNameA(){};
public BeanNameA(long creationtime){
this.creationtime=creationtime;
beanNameB = new BeanNameB();
}
public void makeNewBeanNameB(){
beanNameB = new BeanNameB();
}
}
The prePersist callback in BeanNameB is called when creating the BeanNameA instance. But there is no prePersist callback when the BeanNameA instance is modified by the makeNewBeanNameB() method.
BeanNameA bean = new BeanNameA(123);
manager.persist(bean); //All ok here
bean.makeNewBeanNameB();
manager.flush(); //The new BeanNameB is created but no prePersist callback
Why there is no prePersist callback?
