public class OpenEntityManagerInViewInterceptor extends EntityManagerFactoryAccessor implements AsyncWebRequestInterceptor
This interceptor makes JPA EntityManagers available via the current thread,
which will be autodetected by transaction managers. It is suitable for service
layer transactions via JpaTransactionManager
or JtaTransactionManager as well
as for non-transactional read-only execution.
In contrast to OpenEntityManagerInViewFilter, this interceptor
is set up in a Spring application context and can thus take advantage of
bean wiring.

WebRequestInterceptorAllows for preparing context resources (such as a Hibernate Session) and expose them as request attributes or as thread-local objects.

WebRequestInterceptorAllows for modifying context resources after successful handler execution (for example, flushing a Hibernate Session).
