open class OpenSessionInViewInterceptor : AsyncWebRequestInterceptor
Spring web request interceptor that binds a Hibernate Session to the thread for the entire processing of the request.
This class is a concrete expression of the "Open Session in View" pattern, which is a pattern that allows for the lazy loading of associations in web views despite the original transactions already being completed.
This interceptor makes Hibernate Sessions available via the current thread, which will be autodetected by transaction managers. It is suitable for service layer transactions via org.springframework.orm.hibernate5.HibernateTransactionManager as well as for non-transactional execution (if configured appropriately).
In contrast to OpenSessionInViewFilter, this interceptor is configured in a Spring application context and can thus take advantage of bean wiring.
WARNING: Applying this interceptor to existing logic can cause issues that have not appeared before, through the use of a single Hibernate Session for the processing of an entire request. In particular, the reassociation of persistent objects with a Hibernate Session has to occur at the very beginning of request processing, to avoid clashes with already loaded instances of the same objects.
