object references an unsaved transient instance : save the transient instance before flushing [duplicate]

Question

I have two entities: PlayerProfileEntity & UserInfoEntity I have a join on userInfoEntity & PlaterProfileEntity and saving my record in database like this:

Session session = sessionFactory.openSession();
Transaction tr = session.beginTransaction();
Criteria crit = session.createCriteria(PlayerProfileEntity.class);
player.setUserId(new UserInfoEntity());
player.getUserId().setAddress(user.getUserId().getAddress());
session.save(player);
tr.commit();

I used this assosiation in my PlayerProfileEntity class

@ManyToOne (fetch = FetchType.LAZY)
@Cascade({CascadeType.REFRESH})
@JoinColumn(name="userid")

I am getting this error:

org.hibernate.TransientObjectException: object references an unsaved transient instance - save     the transient instance before flushing: com.shared.entity.UserInfoEntity

Note : If i use CascadeType.All, i get this error:

Cannot add or update a child row: a foreign key constraint fails

Any idea how can i solve this

Thanks

Answer 1

public void savePlayerMethod(PlayerInfoEntity player){

if(player == null){
   player = new PlayerInfoEntity();
}
player.setUserId(getSavedUserInfo());
Session session = SessionFactory.openSession();
Transaction transaction = session.beginTransaction();
session.save(userInfo);
transaction.committ();
}

public UserInfoEntity getSavedUserInfo(){
UserInfoEntity userInfo = new UserInfoEntity();
Session session = SessionFactory.openSession();
Transaction transaction = session.beginTransaction();
session.save(userInfo);
transaction.committ();
}

You should use the CascadeType.PERSIST or CascadeType.ALL
