How to write elasticsearch query aggregation in java?

Question

This is my code in Marvel Sense:

GET /sweet/cake/_search
{
  "query": {
    "bool": {
      "must": [
        {"term": {
          "code":"18"
        }}
      ]
    }
  },
  "size": 0,
  "aggs": {
    "group_by_state": {
      "terms": {
        "field": "id"
      }
    }
  }
}

And I want to write it in Java but I dont't know how.

What version of Elasticsearch are you running?

You can find some examples in the official documentation for the Java client.

But in your case, you need to create one bool/must query using the QueryBuilders and one terms aggregation using the AggregationBuilders. It goes like this:

// build the query
BoolQueryBuilder query = QueryBuilders.boolFilter()
    .must(QueryBuilders.termFilter("code", "18"));

// build the terms sub-aggregation
TermsAggregation stateAgg = AggregationBuilders.terms("group_by_state")
    .field("id");

SearchResponse resp = client.prepareSearch("sweet")
        .setType("cake")
        .setQuery(query)
        .setSize(0)
        .addAggregation(stateAgg)
        .execute()
        .actionGet();
