请教各位大神，，我运行时候报错
org.springframework.orm.hibernate4.HibernateQueryException: could not resolve property: paygroupId of: com.entity.TUBill; nested exception is org.hibernate.QueryException: could not resolve property: paygroupId of: com.entity.TUBill

这个是因为我实体映射写错了吗？还是因为数据库中的类型和实体里面的类型没匹配上？这个怎么解决啊，求指教啊~~~~~~

BigDecimal 改成double试试
