我想通过 JAVA API 为字段映射但失败了。以下是详细信息：

我的数据结构是：

{
  "mje-test-execution-id": "464b66ea6c914ddda217659c84a3cb9d",
  "jvm-free-memory": 315245608,
  "jvm-total-memory": 361758720,
  "system-free-memory": 0,
  "jvm-max-memory": 7600078848,
  "system-total-memory": 34199306240,
  "memory-time-stamp": "2020-03-12T05:12:16.835Z",
  "mje-host-name": "CN-00015345",
  "mje-test-suite-name": "SCF Test no mje version",
  "mje-version": "1.8.7771-SNAPSHOT",
  "mje-test-artifact-id": "msran-regression-tests",
  "mje-test-version": "1.8.7771-SNAPSHOT",
  "stp-id": "vran-stp",
  "mje-test-location": {
    "lat": 58.41,
    "lon": 15.62
  }
}

我想要做的是：将“mje-t​​est-location”类型设置为“geo_point”

我的代码片段：

public void postMapping(String indexName, String field, String type) throws IOException {
        GetIndexRequest request = new GetIndexRequest(indexName);

        boolean exists = client.indices().exists(request, RequestOptions.DEFAULT);
        if (!exists) {
            LOGGER.info("index {} does not exist. Now to post mapping.", indexName);
            PutMappingRequest putMappingRequest = new PutMappingRequest(indexName);
            XContentBuilder builder = XContentFactory.jsonBuilder();
            builder.startObject();
            {

                builder.startObject("properties");
                {
                    builder.startObject(field);
                    {
                        builder.field("type", type);
                    }
                    builder.endObject();
                }
                builder.endObject();
            }
            builder.endObject();
            putMappingRequest.source(builder);
            //

            AcknowledgedResponse putMappingResponse = client.indices().putMapping(putMappingRequest,
                    RequestOptions.DEFAULT);

            boolean acknowledged = putMappingResponse.isAcknowledged();
            if (acknowledged) {
                LOGGER.info("Succeed to put mapping: field:{}, type: {}", field, type);
            }
        }

        LOGGER.info("Fail to put mapping due to index {} already exist, ", indexName);
    }

错误信息：

15:59:54.397 [main] DEBUG org.elasticsearch.client.RestClient - request [PUT http://seliiuapp00269.lmera.ericsson.se:9208/mje-scf-v2-20200313-post/_mapping?master_timeout=30s&timeout=30s] returned [HTTP/1.1 400 Bad Request]

我将发布@Mincong 的评论作为答案，因为我导入了从 github 搜索中发现的错误导入：

你的类“PutMappingRequest”的全名是什么：org.elasticsearch.action.admin.indices.mapping.put.PutMappingRequest 或 org.elasticsearch.client.indices.PutMappingRequest？你应该使用第二个。

您需要像这样指定文档类型：

putMappingRequest.type("_doc");

并且还需要在这里指定字段的类型：

builder.field("type", type);

喜欢：("type", "text")或("type", "long")，("type", "date")......

您可以在此处查看数据类型
