Hibernate报错session was already closed

org.hibernate.sessionException session was already closed

因为hibernate里如果不是用getSession()或者openSession获取一个session对象,而是采用getCurrentSession获取session对象时，当事务结束的时候，不管是提交还是回滚事务，hibernate都会自动关闭session的.，如果此时还写session.close();会关闭两次sessoin,所以报错session was already closed;解决办法是将此时不要session.close();
