Question

If any body has worked with FDS /Hibernate/Spring
pls post the sample.

Answer 1

The posts here that point to examples of Spring + FDS and
separate examples of Hibernate + FDS and then say combining the two
should be easy seem to be missing the point. This is not as easy an
straight forward as it seems it should be.
Spring + Hibernate + FDS is a completely different animal
because you are getting Spring to handle the Session Factory
configuration and your DAO's as Spring beans but you also want the
handling of lazy initialization and proxy serialization as shown in
the HibernateAssembler.
The current HibernateAssembler code handles all of the
Hibernate setup. I would much rather have Spring do this. What I
would like is for my HibernateProxy's for non initialized
associations to be serialized rather than traversed resulting
LazyInitializationExceptions. The HibernateAssembler seems to
tackle this with a very mysterious piece of code:
PropertyProxyRegistry.getRegistry().register(HibernateProxy.class,
new HibernatePropertyProxy());
PropertyProxyRegistry and HibernatePropertyProxy are not
documented anywhere, and in fact a Google on PropertyProxyRegistry
returns 0 results. However, my intuition tells me this piece of
code should tell serialization to proxy the HibernateProxy with a
flex class called HibernatePropertyProxy which will just serialize
an id of an association rather than attempting to serialize the
uninitialized associated class.
I cannot get this to work though and as there is no
documentation and no discussion on these classes, I have no way of
verifying it. If my intuition is correct, this is a very useful
mechanism. I only wish it was documented b/c if it did work as
expected it would make a Hibernate + Spring + FDS implementation
pretty easy.
Anyone know anything about this?
