Hello,
Subaggregations in the java client can be added by calling the aggregations method provided in the Aggregation class itself; your example would look something like this:

        esClient.search(s -> s
                .index("index")
                .aggregations("dateHistogram", a1 -> a1
                    .dateHistogram(dh -> dh
                        .field("createTime")
                        ...)
                    .aggregations("terms", a2 -> a2
                        .terms(ts -> ts
                            .field("effectedObject.keyword")
                            ...)
                        .aggregations("aggs", a3 -> a3
                            .min(m -> m
                                .field("holdFolder")))))
            ,Object.class);
