@Nullable
T doInHibernate(Session session)
         throws HibernateException
```
    Gets called by HibernateTemplate.execute with an active Hibernate Session. Does not need to care about activating or closing the Session, or handling transactions.
    Allows for returning a result object created within the callback, i.e. a domain object or a collection of domain objects. A thrown custom RuntimeException is treated as an application exception: It gets propagated to the caller of the template.
    参数:
    session - active Hibernate session
    返回:
    a result object, or null if none
    抛出:
    HibernateException - if thrown by the Hibernate API
