本文介绍了一个自定义的 Hibernate 会话管理过滤器，该过滤器继承了 Spring 的 OpenSessionInViewFilter，并修改了默认的 flush 模式为 COMMIT，确保在事务提交时进行显式刷新。

public class OpenSessionInViewFilter extends org.springframework.orm.hibernate3.support.OpenSessionInViewFilter {

        /**
         * we do a different flushmode than in the codebase
         * here
         */
        protected Session getSession(SessionFactory sessionFactory) throws DataAccessResourceFailureException {
                Session session = SessionFactoryUtils.getSession(sessionFactory, true);
                session.setFlushMode(FlushMode.COMMIT);
                return session;
        }
        /**
         * we do an explicit flush here just in case
         * we do not have an automated flush
         */
        protected void closeSession(Session session, SessionFactory factory) {
                session.flush();
                super.closeSession(session, factory);
        }
}
