MyBatis注释动态查询，其中包含变量select和group

Question

MyBatis select查询是否可以读取Select和Group By命令的变量值？如果可能的话，我应该如何将aggregationKeys变量放在那个位置？ （查看代码）：

@Select({"SELECT #{aggregationKeys}, SUM(value) " +
            "FROM usage_counter WHERE " + /*zrobic mape i pociagnac to tak, ze: (#{zmyslona wartosc} IS NULL OR api_consumer) itd*/
            "(#{apiConsumerIds} IS NULL OR #{apiConsumerIds} like '%,'||api_consumer||',%' ) AND " +
            "(#{serviceIds} IS NULL OR #{serviceIds} like '%,'||service||',%' ) AND " +
            "(#{rateplanIds} IS NULL OR #{rateplanIds} like '%,'||rateplan||',%' ) AND " +
            "(#{dateFrom} IS NULL OR date >= #{dateFrom} ) AND " +
            "(#{dateTo} IS NULL OR date <= #{dateTo} ) AND " +
            "(#{statuses} IS NULL OR #{statuses} like '%,'||counter_status||',%' ) " +
            "GROUP BY ||#{aggregationKeys}||"})
    @Results({
            @Result(property = "date", column = "date"),
            @Result(property = "apiConsumerId", column = "api_consumer"),
            @Result(property = "serviceId", column = "service"),
            @Result(property = "value", column = "value")
    })
    List<AggregatedUsage> getAggregatedUsageCounters(@Param("aggregationKeys") String aggregationKeys, @Param("dateFrom") Date dateFrom, @Param("dateTo") Date dateTo, @Param("apiConsumerIds") String apiConsumerIds, @Param("serviceIds") String serviceIds, @Param("statuses") String statuses);

编辑：或者是否可以通过两个或多个值在Java流中进行分组（在这种情况下最多4个）？

第二次编辑： - 确定它是可能的，但是它使得流非常复杂，我觉得无效。
