hello there,

im a noobie.

For mapping a class to database table, we usually have this Identifier/id column.

I found out that the class implementation provided by me, not necessarily need to have function to setId; something like public void setId(int id)

Even the id attribute could be put as private to the class.
So i wonder, how could hibernate help me extract/set the id from database table accordingly?

Any reference/help/links/articles are very much appreciated

Regards,
Robin

usually one would leave getID() public, make setID(..) private and let hibernate generate the identifier like this



there are a number of different generators (besides native) available, and you could even implement your own

alternatively you could not have a getID or setID property at in your domain object all like this



you can then retrieve the id with session.getIdentifier, but because the ID is not in the object you can't detach/reatach these objects from a session
