spring - 找不到Elasticsearch Spring JSONObject [“hits”]

Question

我正在尝试对全文查询进行搜索
如果我得到http:// localhost:8080 / search / query / tes
它应显示用户姓氏或名字包含tes。我实现了它们。但是出了点问题，它说找不到匹配(找不到JSONObject [“hits”])。
使用Elasticsearch的Spring Boot

@Service
public class SearchService implements ISearchService {

@Value("${api.elasticsearch.uri}")
private String elasticSearchUri;

@Value("${api.elasticsearch.search}")
private String elasticSearchSearchPrefix;

private static final Logger LOGGER = LoggerFactory.getLogger(SearchService.class);

@Override
public ResultQuery searchFromQuery(String query) throws IOException {
    String body = HelperFunctions.buildMultiIndexMatchBody(query);
    return executeHttpRequest(body);
}

/**
 * Fetch resultQuery from elastic engine for the given body
 *
 * @param body String
 * @return ResultQuery
 * @throws IOException IOException
 */
private ResultQuery executeHttpRequest(String body) throws IOException{
    try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
        ResultQuery resultQuery = new ResultQuery();
        HttpPost httpPost = new HttpPost(HelperFunctions.buildSearchUri(elasticSearchUri
                , "", elasticSearchSearchPrefix));
        httpPost.setHeader(Accept, application/json);
        httpPost.setHeader(Content-type, application/json);
        try {
            httpPost.setEntity(new StringEntity(body, UTF-8));
            HttpResponse response = httpClient.execute(httpPost);
            String message = EntityUtils.toString(response.getEntity());
            JSONObject myObject = new JSONObject(message);
            if(myObject.getJSONObject(hits)
                    .getInt(total) != 0){
                resultQuery
                        .setElements(myObject
                                .getJSONObject(hits)
                                .getJSONArray(hits)
                                .toString());
                resultQuery
                        .setNumberOfResults(myObject.getJSONObject(hits)
                                .getInt(total));
                resultQuery.setTimeTook((float) ((double) myObject.getInt(took) / 1000));
            } else {
                resultQuery.setElements(null);
                resultQuery.setNumberOfResults(0);
                resultQuery.setTimeTook((float) ((double) myObject.getInt(took) / 1000));
            }
        } catch (IOException | JSONException e) {
            LOGGER.error("Error while connecting to elastic engine --> {}", e.getMessage());
            resultQuery.setNumberOfResults(0);
        }

        return resultQuery;
    }
}

}

是认证问题。我在开始连接basicauth(user:pass)时创建了一个服务，但是由于某种原因，该服务在该json REST页面上没有标题。所以我添加了 token 头，voilà它起作用了。
