hibernate处理null 时提示:Property path [...] does notreference a collection

Hibernate判断某属性不为null 且不可为空时出现Property path [...] does notreference a collection 的问题

处理空的方法:

isNotEmpty(propertyName)、isNotNull(propertyName)

但是此时报都会报Property path [...] does notreference a collection异常

此时需要将不为空或空查询改为Property.forName("isCancelled").isNotNull()

即:

criteria.add(Restrictions.or(Property.forName("isCancelled").isNotNull(),Restrictions.ne("isCancelled",null))); ions.ne("lqprovince", ""));
或者
criteria.add(Restrictions.or(Restrictions.ne("isCancelled",null), Property.forName("isCancelled").isNotNull()));
