Java 不要使用foreach获取mybatis xml中的列表对象值

现在我已经知道如何在MyBatis中的xml foreach循环中获取list参数中的值，但如果在foreach循环中没有，如何获取list元素值？这是我的代码：

 <select id="selectMultiRoomSeatForUpdateEnhance" resultMap="roomSeat">
        set @update_id := 0;
        UPDATE r_room_seat s
        SET s.status = 1,
        room_play_id = (SELECT @update_id := max(room_play_id)),
        s.user_id = (
            case when s.seat_num = 1
            then #{queryParam.users[0].id,jdbcType=BIGINT}
            when s.seat_num = 2
            then #{queryParam.users[1].id,jdbcType=BIGINT}
            else 1 end
        ),
        s.robot_flag = (
            case when s.seat_num = 1
            then #{queryParam.users[0].isRobot,jdbcType=BIGINT}
            when s.seat_num = 2
            then #{queryParam.users[1].isRobot,jdbcType=BIGINT}
            else 0 end
        ),
        WHERE s.status = 0
        and s.online = 1
        and s.room_play_id in (
            select room_play_id
            from (
                select room_play_id as room_play_id
                from r_room_seat
                where status = 0
                and app_id = 4
                group by room_play_id
                having count(*) = 2
                limit 1
            ) a
        )
        and s.room_id = #{queryParam.roomTypeId,jdbcType=BIGINT}
        LIMIT 2;
        select
        <include refid="Base_Column_List"/>
        from r_room_seat
        where room_play_id = @update_id
        limit 1;
    </select>

参数如下所示：

/**
     * @param queryParam
     * @return
     */
    RoomSeat selectMultiRoomSeatForUpdateEnhance(@Param("queryParam") Map<String, Object> queryParam);

传递参数：

private RoomSeat getBatchAvailableSeatEnhance(Long roomTypeId, RoomBatchMatchRequest request) {
        Map<String, Object> queryParam = new HashMap<>();
        queryParam.put("roomTypeId", roomTypeId);
        queryParam.put("users", request.getUsers());
        RoomSeat roomSeat = roomSeatCustomMapper.selectMultiRoomSeatForUpdateEnhance(queryParam);
        return roomSeat;
    }

这样指定queryParam.users[1].id是否正确
