What is the best way to intercept calls to initialise lazy fields?

The classes org.hibernate.intercept.FieldInterceptor and org.hibernate.intercept.LazyInitializer sound interesting but I'm not sure how to provide one of these - do I set some config or set some property on an object?

The background is that I am writing a swing app, utilising spring. I want to intercept a call to lazy fields so I can attach the session (I have a global session) to the current thread so it can hydrate the field.

thanks, Tom.

Have a read of http://www.hibernate.org/43.html on the downsides of your approach (especially the section "Why can't Hibernate just load objects on demand?"), and how to implement a better alternative.
