# I've set echo=True when doing create_engine, so I can see all the sql stmt
# DBSession is ScopeSession(thread_local) and autocommit is False
session = DBSession() 
session.add(somemodel)
# 
try:
    session.flush()
    raise Exception()
    session.commit()
except SQLAlchemyError as e:
    session.rollback()
finally:
    session.close()

根据 SQLAlchemy 文档：

The close() method issues a expunge_all(), and releases any transactional/connection
resources. When connections are returned to the connection pool, transactional state is
rolled back as well.

我希望在执行“session.close()”时看到日志“rollback”
