Question

I’m writing a hibernate interceptor and I need to access the hibernate session object. Is their a direct way to access the hibernate session using the interceptor?

What I’m trying to do is to find out what database hibernate has connected to. For various reasons, this is going to be impractical to store as thread local data.

There seems no “official” way of getting hold of the session object neither through o.h.Interceptor neither through o.h.EmptyInterceptor. Moreover, Interceptor‘s Javadoc says:

There might be a single instance of Interceptor for a SessionFactory,
or a new instance might be specified for each Session. Whichever
approach is used, the interceptor must be serializable if the Session
is to be serializable. This means that SessionFactory-scoped
interceptors should implement readResolve().

The Session may not be invoked from a callback (nor may a callback
cause a collection or proxy to be lazily initialized).

The only way to get this information seems to be by using reflection and has been answered here.
