Hi,

I am trying to keep track of entity creator, in this case an User entity.
If an user self-register, the creator would be him(her)self.

Code:

class User {
    Long id;
    String name;
    User creator;
}


User u = new User();
u.setName("foo");
u.setCreator(u);

session.saveOrUpdate(u);

I assume hibernate is clever enough to handle self-referencing entities.

-cs

works as advertised :-)

Using the same example, does the "creator" gets loaded at the same time the "entity" got loaded ?

It seems to be doing so when I looked at the generated SQL in the log file.

How do I make the loading of the "creator" lazy ? I don't see any "lazy" attribute in the "many-to-one" element in the dtd.

lazy="true" attribute on the class element
