Java org.hibernate.hql.ast.QuerySyntaxException

我得到了这个异常：org.hibernate.hql.ast.QuerySyntaxException:子树的意外结束 当我执行以下查询时：

<query name="fetchCSpecificationByAttIdExtId">      
 <![CDATA[from
> CProductSpecifications where attributeId=:attributeId  and
> extractedProductId in (:extractedList)]]>     </query>

调用此查询的服务方法是：

List<CProductSpecifications> cSpecList=(List<CProductSpecifications>)this.baseDao.findByNamedQueryAndNamedParam("fetchCSpecificationByAttIdExtId", new String[]{"attributeId","extractedList"},new Object[]{aid,extractedList});

List cSpecList=（List）this.baseDao.findByNamedQueryAndNamedParam（“fetchcsspecificationbyattidextid”，新字符串[]{“attributeId”，“extractedList”}，新对象[]{aid，extractedList}）；

是否extractedList为空？试着先做一个空支票

List<CProductSpecifications> cSpecList=(List<CProductSpecifications>)this.baseDao.findByNamedQueryAndNamedParam("fetchCSpecificationByAttIdExtId", new String[]{"attributeId","extractedList"},new Object[]{aid,extractedList});
