org.hibernate.hql.ast.QuerySyntaxException

Question

我收到此异常：org.hibernate.hql.ast.QuerySyntaxException：意外的子树结束 当我执行以下查询时：

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

详细的堆栈跟踪是：

  org.hibernate.hql.ast.QuerySyntaxException: unexpected end of subtree
   [ from com.bemol.dao.product.CProductSpecifications where attributeId=:attributeId  and extractedProductId in ()
         ]

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});

Answer 1

也许extractList是空的？首先尝试进行空检查。
