Spring boot 如何在Java中使用RESTAPI对弹性搜索中的对象数组进行索引

我使用ES7.5.1存储数据，并使用RESTAPI Spring boot。 它可以很好地处理单个对象，但当我试图传递一个对象数组时，它抛出了错误的请求或不可接受的错误406

代码：

您需要使用批量API。 此API接受JSON NDJSON结构中的对象数组

在单个API调用中执行多个索引或删除操作。这样可以减少开销，并大大提高索引速度

我们可以使用RestHighLevelClient将批量数据索引到弹性数据中

Maven依赖项：

<dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-high-level-client</artifactId>
        <version>${elastic.version}</version>
    </dependency>

    <dependency>
        <groupId>org.elasticsearch.client</groupId>
        <artifactId>elasticsearch-rest-client</artifactId>
        <version>${elastic.version}</version>
    </dependency>

用法：

@Autowired
private RestHighLevelClient restHighLevelClient;

@Override
public void storeBulkDataInElastic(List<UserBean> dataBeanList) throws IOException
{
    BulkRequest bulkRequest = new BulkRequest();
    ObjectMapper objectMapper = new ObjectMapper();
    dataBeanList.forEach(data -> {
        IndexRequest indexRequest = new IndexRequest("ElasticIndex", "ElasticType", "ElasticId").source(objectMapper.convertValue(data, Map.class));
        bulkRequest.add(indexRequest);
    });

    restHighLevelClient.bulk(bulkRequest, RequestOptions.DEFAULT);
}

@Bean
protected RestHighLevelClient createInstance() throws Exception
{
    try
    {
        RestHighLevelClient restHighLevelClient = new RestHighLevelClient(RestClient.builder(new HttpHost("localhost", "9200", "http")));
    }
    catch (Exception e)
    {
        LOG.error("Error while creating RestHighLevelClient", e);
    }
    return restHighLevelClient;
}

@Autowired
private RestHighLevelClient restHighLevelClient;

@Override
public void storeBulkDataInElastic(List<UserBean> dataBeanList) throws IOException
{
    BulkRequest bulkRequest = new BulkRequest();
    ObjectMapper objectMapper = new ObjectMapper();
    dataBeanList.forEach(data -> {
        IndexRequest indexRequest = new IndexRequest("ElasticIndex", "ElasticType", "ElasticId").source(objectMapper.convertValue(data, Map.class));
        bulkRequest.add(indexRequest);
    });

    restHighLevelClient.bulk(bulkRequest, RequestOptions.DEFAULT);
}
