Called immediately after instantiation of this factory.

Essentially equivalent to constructor injection, but contracted
here via interface.
Params:
entityName – The name of the entity for which this factory should
generate proxies.
persistentClass – The entity class for which to generate proxies;
not always the same as the entityName.
interfaces – The interfaces to expose in the generated proxy; HibernateProxy is already included in this collection.
getIdentifierMethod – Reference to the identifier getter method;
invocation on this method should not force initialization
setIdentifierMethod – Reference to the identifier setter method;
invocation on this method should not force initialization
componentIdType – For composite identifier types, a reference to the type of the identifier property; again accessing the id should generally not cause initialization - but need to bear in mind 
mappings.
Throws:
HibernateException – Indicates a problem completing post
instantiation initialization./**
