java - 如何通过 bulkrequest 更新嵌套的 elasticsearch 值？

Question

我们正在使用 AWS Elasticsearch - 7.7 版本

我已经关注了Update nested field in an index of ElasticSearch with Java API

我有以下 JSON Elasticsearch

 {
    "_index": "product",
    "_type": "_doc",
    "_source": {
        "id": 1,
        "name": "test",
        "properties": [{
            "id": 1,
            "qty": 10
        }]
    }
}

我有以下代码

 BulkRequest request = new BulkRequest();
 request.add(new UpdateRequest(<ES Endpoint>, 1))
                        .doc(XContentType.JSON, "name", "TEST 1"));
BulkResponse bulkResponse = restClient.bulk(request, RequestOptions.DEFAULT);   

我应该如何更新“属性”值“数量”？

您可以传递一个包含所有字段的 map 以在 doc() 调用中更新:

Map doc = new HashMap();
doc.put("name", "TEST 1");
doc.put("qty", 12);
request.add(new UpdateRequest("index", 1)
                    .doc(XContentType.JSON, doc));
