Answer 1

You can specify it by schema element while defining table for your entity.

@Table(name="TABLE_NAME", schema="SCHEMA_NAME")

Else, you can use separate EntityManager pointing to respective schema & then use the same entity, as their structure is similar.

Edit : You can have separate configuration files for each schema & then build SessionFactory from it, below is some pseudo-code for it.

SessionFactory sf_1 = new  Configuration().configure("schema1config.cfg.xml").buildSessionFactory();
SessionFactory sf_2 = new Configuration().configure("schema2config.cfg.xml").buildSessionFactory();

session_1 = sf_1.openSession();  //-- Similarly for other

You can refer this link for further details to map multiple schema, but it isn't hibernate specific.
