You can make a custom repo to achieve the same using mongoTemplate.

    SampleOperation sample = Aggregation.sample(1);
        Aggregation aggregation = newAggregation(sample);
        AggregationResults<T> result =
            this.mongoTemplate.aggregate(aggregation, "CollectionToSearch","Return-type-object");
    return result.getMappedResults();
