求助大神，关于hibernate里面的criteria查询

请问下在hibernate里面，用criteria的方式，写出主表左连接子表。并且查询条件是主表和子表的字段，请帮忙写个demo,单表的写过，多表的没写过，谢谢

Criteria criteria = this.sessionFactory.getCurrentSession().createCriteria(Record.class,"re");
criteria.add(Restrictions.eq("re.confid", confID));
criteria.add(Restrictions.eq("re.srcpath",srcpath));
criteria.add(Restrictions.eq("re.transcode_start_time",dateTime));
criteria.createAlias("re.rc", "rrc", CriteriaSpecification.LEFT_JOIN);
criteria.add(Restrictions.eq("rrc.quality",quality));
criteria.add(Restrictions.eq("rrc.video_background",videoBackground));
criteria.add(Restrictions.eq("rrc.transparency",transparency));
criteria.add(Restrictions.eq("rrc.layoutId",layoutId));
criteria.setFetchMode("rrc", FetchMode.JOIN);
//
