sql:

<![CDATA[
         SELECT inn.inner_org_id, inn.org_code FROM inner_org inn, org_relation rel WHERE inn.inner_org_id=rel.relation_id and rel.parent_id = #{parentId}
     ]]>

解決方法1：

將參數名（上面的例子為’parentId’）替換為”_parameter” 

 

解決方法2：

Dao層接口方法的參數聲明加上@Param("parentId")

如：List<Inner> findInnerByPid(@Param("parentId") String parentId);
