hql查询报错。。。。实体类问题

hql语句:
String hql="from CouponPublishEntity e inner join e.couponpool c where c.owner='"+userId+"' and e.pubid in ("+ids+") ";
报错
[org.jeecgframework.core.common.exception.GlobalExceptionResolver]全局处理异常捕获:
org.hibernate.QueryException: could not resolve property: couponpool of: com.sendiy.hh.coupons.entity.CouponPublishEntity [from com.sendiy.hh.coupons.entity.CouponPublishEntity e inner join e.couponpool c where c.owner='4028668150c6aedb0150c6ddde750005' and e.pubid in ('2') ]
问题是实体类写错了吗,还是语法错了·

    实体类中没有找到couponpool,看是不是你实体类中不是这样写的, hql区分大小写

    CouponPublishEntity这个实体和CouponPoolEntity这个实体不是两个实体吗,那你怎么从CouponPublishEntity 中拿到CouponPoolEntity

    String hql="from CouponPublishEntity e inner join CouponPoolEntity c where c.owner='"+userId+"' and e.pubid in ("+ids+") ";
