In my application I need to access and create tables daily, as would be the mapping with annotations? For example on 2009-02-11, I have create table_20090211 with id "id_table_20090211", on 2009-02-12, I have crate table_20090212 with id "id_table_20090212"...

Sorry for my english, I'm learning yet.

It would be interesting to know the use case which makes you need to create new tables on a daily basis like that.

The only thing I can think of is to find a way to use reflection and edit the class in memory. If the tables always have the same structure this shouldn't be that hard.

I wouldn't know how to do this but you'll have to make sure the session factory knows about this maybe you'll have to recreate the sessionFactory and configuration everytime?

which database u r using

i suggest that u should use table partitioning
