mybatis查询参数为List<String>，输出结果为List<String>写法

    <!-- 产线大屏，事件列表，根据流程实例ID查询已经撤销的流程-->
    <select id="getStopedProcessInstanceByIds" parameterType="java.util.List" resultType="string">
        SELECT
            T1.PROC_INST_ID_
        FROM `act_hi_procinst` as T1
        join act_hi_comment as T2 on T1.PROC_INST_ID_=T2.PROC_INST_ID_
        WHERE T2.TYPE_='Stop'
        <if test="processInstanceIds!=null">
            and t1.PROC_INST_ID_ in
            <foreach collection="processInstanceIds" index="index" item="item" open="(" separator="," close=")">
                #{item}
            </foreach>
        </if>
        ORDER BY T1.START_TIME_ DESC
    </select>

重点是parameterType为：java.util.List

resultType为：string
