Hi,

I am running into an issue where Hibernate automatically calls update on my domain object whenever I retrieve from the database and the use a setter method to change a value. My understanding is that I should be able to set the value and then explicitly call update on the domain object in order for it to update in the dB. Please let me know what is wrong.

Thanks for your help,

Here is my code snippet:

//retrieves the appropriate record from the db based on the id
Person adult = (Person)getService().getPerson("34");

//upon setting of this ID, "update" is called to persist this to the db. //Why?
adult.setFamId(new Long("887"));

One of main features of Hibernate is automatic dirty checking, which means that Hibernate will automatically detect changes you make to your objects and update the database when the transaction is committed.

If you don't want this to happen you need to evict the object in question from the Hibernate session by calling Session.evict().

Thanks for the information, Nordborg. Is there a way to disable automatic dirty checking for all objects? Where is this property being set?

Thanks for your help,

Not that I know of. After all, this is one of the main Hibernate features. I think it has to be done programmatically one way or the other.

The Session.update() method should only be used for objects that are previously not associated with the session (for example, has been evicted with Session.evict()).
