原标题:"org.hibernate.HibernateException: Illegal attempt to associate a collection with two open sessions" even when the context is Thread
问题回答
Calling openSession() does not associate the resulting Session object with Hibernate s current session context. However, if you call getCurrentSession() and no session exists, then Hibernate will open a new session and associate it with the context. In other words, you need to replace your call to openSession() with a call to getCurrentSession().
