https://hibernate.atlassian.net/browse/HHH-11259 lists some other
possibilities for things we might consider for accessing through
ManagedBeanRegistry. We discussed Interceptor in Paris - I can definitely
see that with some caveats/restrictions. Add it to that list or create a
As for chaining Interceptors, I guess it depends how that is exposed. E.g.
a comma-separated list in settings would inherently imply ordering. That
works for SessionFactory-scoped Interceptors. I'm not sure we need a
composite though wrapping the individual Interceptors, a List<Interceptor>
would suffice and save some memory (granted a tiny amount). For
Session-scoped Interceptors we would need to account for a few things, but
its certainly possible. Supposing there are also SessionFactory-scoped
1. How would a user indicate that the Session-scoped Interceptors should
replace the SessionFactory-scoped ones versus adding to them. What's the
ordering there - SessionFactory-scoped Interceptors first? Or
2. How would a user indicate that a Session should have no
Interceptors? That is a common requirement.
3. Probably some others I am not thinking of.
