所有已知子接口:

EventSource, HibernateEntityManager, HibernateEntityManager, HibernateEntityManagerImplementor, QueryProducerImplementor, Session, SessionImplementor, SharedSessionContract, SharedSessionContractImplementor, StatelessSession

所有已知实现类:

```
public interface QueryProducer
```
Contract for things that can produce Query instances. Expected implementors include Session and StatelessSession.
It defines these query creation methods in the signature defined by EntityManager. In a way it defines a subset of the EntityManager contract to be reused by both Session and StatelessSession.
