您好我正在尝试启动嵌入式弹性搜索服务器，然后使用 java 高级休息客户端将文档插入到索引中。但是我收到以下错误。

com.openmind.primecast.web.rest.PerformanceReportingIntTest  Time elapsed: 68.723 sec  <<< ERROR!
org.elasticsearch.action.ActionRequestValidationException: Validation Failed: 1: source is missing;2: content type is missing;

以下是我的源代码。简而言之，我有一个名为汽车的索引，并在其下键入汽车。我正在尝试使用 java 高级休息客户端在汽车下插入一个文档。

        public class PerformanceReportingIntTest extends AbstractCassandraTest {

            private static EmbeddedElastic embeddedElastic;

            @BeforeClass
            public static void startElasticServer() throws FileNotFoundException, IOException, InterruptedException {

                embeddedElastic = EmbeddedElastic.builder().withElasticVersion("6.6.1")

                client = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", 9350, "http")));

                BulkRequest request = new BulkRequest();
                Map<String, String> m1 = new HashedMap<>();
                m1.put("_id", "1");
                m1.put("manufacturer", "Benz");
                m1.put("model", "A Class");
                m1.put("description", "Latest Model");

                JSONObject jsonObj = new JSONObject(m1);

                request.add(new IndexRequest("cars", "car"), jsonObj);
                BulkResponse response = client.bulk(request, RequestOptions.DEFAULT);
            }

            private static InputStream getSystemResourceAsStream() throws FileNotFoundException {
                ClassLoader classloader = Thread.currentThread().getContextClassLoader();
                InputStream is = classloader.getResourceAsStream("config/elasticsearch/car-mapping.json");
                return is;
            }

            @Test
            public void test() {

            }

            @AfterClass
            public static void close() throws IOException {
                client.close();
                embeddedElastic.stop();
            }

        }

这是我的 car-mapping.json 文件

{
  "car": {
    "properties": {
      "manufacturer": {
        "type": "text",
        "index": "false"
      },
      "model": {
        "type": "text",
        "index": "true"
      },
      "description": {
        "type": "text"
      }
    }
  }
}

非常感谢任何帮助谢谢

您为什么不按照文档的建议尝试？

BulkRequest request = new BulkRequest();
Map<String, Object> jsonMap = new HashMap<>();
jsonMap.put("manufacturer", "Benz");
jsonMap.put("model", "A Class");
jsonMap.put("description", "Latest Model");
IndexRequest indexRequest = new IndexRequest("posts").id("1").source(jsonMap);
request.add(indexRequest);

BulkResponse response = client.bulk(request, RequestOptions.DEFAULT);
