Serializable, CurrentSessionContext
```
public class ThreadLocalSessionContext
extends AbstractCurrentSessionContext
```
A CurrentSessionContext impl which scopes the notion of current session by the current thread of execution. Unlike the JTA counterpart, threads do not give us a nice hook to perform any type of cleanup making it questionable for this impl to actually generate Session instances. In the interest of usability, it was decided to have this default impl actually generate a session upon first request and then clean it up after the Transaction associated with that session is committed/rolled-back. In order for ensuring that happens, the sessions generated here are unusable until after SharedSessionContract.beginTransaction() has been called. If close() is called on a session managed by this class, it will be automatically unbound. Additionally, the static bind(org.hibernate.Session) and unbind(org.hibernate.SessionFactory) methods are provided to allow application code to explicitly control opening and closing of these sessions. This, with some from of interception, is the preferred approach. It also allows easy framework integration and one possible approach for implementing long-sessions. The buildOrObtainSession(), isAutoCloseEnabled(), isAutoFlushEnabled(), getConnectionReleaseMode(), and buildCleanupSynch() methods are all provided to allow easy subclassing (for long-running session scenarios, for example).

```
public static Session unbind(SessionFactory factory)
```
    Disassociates a previously bound session from the current thread of execution.
    
    参数:
    
    factory - The factory for which the session should be unbound.
    
    返回:
    
    The session which was unbound.
