将sql写到xml里

<query name="hql"><!-- hql用标签 -->
    		from TClassification t where t.classificationPid=:parentid
    </query>
    
    <sql-query name="sql"><!-- sql用标签 -->
    	<return alias="ss" class="com.entity.Person"></return><!-- 约束返回的实体 -->
        <return-scalar column="c" type="int"/><!-- 约束返回的实体 -->
    	<![CDATA[
    		select  
    			{person.*}
    			count(*)over() c
    		from table_person person 

    	]]>	
    </sql-query>

basedao

@Override//也可以查sql-query标签里的sql语句但如果没用return标签约束的话返回的是Object数组的list
