如何在Java中使用API更新（版本5）更新ElasticSearch中的hashmap数据？

我正在尝试使用以下代码更新Elastic Search Server中的数据

1） 我已使用以下方法在弹性搜索中插入数据

 HashMap<String, String> hmExtra = new HashMap<String, String>(); 
 hmExtra.put("One", "1");
 hmExtra.put("Two", "2");


 HashMap<String, String> data = new HashMap<String, String>();
 data.put("case_name","Test");
 data.put("case_extra",hmExtra);


 IndexRequest indexRequest = new IndexRequest("org-8").type("Group").source(data);

 IndexResponse response = client.index(indexRequest, header);

插入数据（HashMap）后，它将成功地插入到搜索中

2） 正在尝试更新相同的

之后，当我试图用下面的代码更新case_extra时。搜索查询正在显示现有值

 HashMap<String, String> hmExtra = new HashMap<String, String>(); 
 hmExtra.put("One", "9");

HashMap<String, String> data = new HashMap<String, String>();
 data.put("case_name","Test2");
data.put("case_extra",hmExtra);


UpdateRequest request = new UpdateRequest("org-8", "Group", "AW4gTZwCAdqCPewR2ukW").doc(data);
UpdateResponse updateResponse = client.update(request);

根据上述结果，未从案例中删除键“2”

我需要帮助在elasticsearch中使用Api更新，我尝试了上面的代码，问题是从case_extra中删除的HashMap的第二个值

提前谢谢

更新

这是我试过的代码

在请求更新之前，文档如下所示：

{
  "_index": "org-8",
  "_type": "Group",
  "_id": "AW4cWb2g90EOmg5E-TFl",
  "_version": 22,
  "found": true,
  "_source": {
    "case_name": "Test1",
    "case_extra": {
      "One": "1",
      "Two": "2"
    }
  }
}

更新请求代码，与Garvit Khamesra在回答中给出的代码相同：

    RestHighLevelClient client = new RestHighLevelClient(
            RestClient.builder(new HttpHost("localhost", 9200,"http")));

    HashMap<String, String> hmExtra1 = new HashMap<String, String>();
    hmExtra1.put("One", "9");

    Map<String, Object> data1 = new HashMap<>();
    data1.put("case_extra",hmExtra1);
    data1.put("case_name", "Test2");

    Map<String, Object> parameters = Collections.singletonMap("val", data1);

    UpdateRequest request = new UpdateRequest("org-8", "Group", "AW4cWb2g90EOmg5E-TFl");

    Script script = new Script(ScriptType.INLINE, "painless",
                               "ctx._source = params.val", parameters);
    request.script(script);

    try {
        UpdateResponse updateResponse = client.update(request);
        System.out.println(updateResponse.getGetResult().sourceAsString());
    } catch (Throwable e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

我使用的依赖项如下所示：

    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-high-level-client</artifactId>

您尝试的是弹性搜索的部分更新方法。我们需要使用脚本更新

    RestHighLevelClient client = new RestHighLevelClient(
            RestClient.builder(new HttpHost("localhost", 9200,"http")));

    HashMap<String, String> hmExtra1 = new HashMap<String, String>();
    hmExtra1.put("One", "9");

    Map<String, HashMap<String, String>> data1 = new HashMap<>();
    data1.put("case_extra",hmExtra1);

    Map<String, Object> parameters = singletonMap("val", data1);

    UpdateRequest request = new UpdateRequest("org-8", "Group", "CBCyJm4BWKXF8n_XGsze");

    Script script = new Script(ScriptType.INLINE, "painless",
                               "ctx._source = params.val", parameters);
    request.script(script);

    UpdateResponse updateResponse = client.update(request);

在ES 7.9中，这也适用于使用UpdateByQueryRequest

Map Map=newhashmap（）

我已经通过了这个链接，但它与我想要的完全不同。我已经更新了我的问题。请检查。我已经编辑了我的答案。您能运行它并检查吗？我在“client.update（updateRequest.get（）；”行中没有看到get（）方法你能告诉我你使用的弹性搜索的确切版本吗？通过你的代码，我得到的错误是“ElasticsearchStatusException[Elasticsearch exception[type=非法参数\u exception，reason=[script]未知字段[source]，未找到解析器]”
