SpringBoot中对Elasticsearch查询结果返回最好的读取方式

@Autowired
ObjectMapper objectMapper;
@Resource
RestHighLevelClient elasticsearchClient;

@Override
public List<PagePerformance> findByUrl(String url) {
    List<PagePerformance> ret = new ArrayList<>();

    sourceBuilder.query(createMatcher("url", url));
    searchRequest.source(sourceBuilder);
    RequestOptions options = RequestOptions.DEFAULT;
    try {
        SearchResponse searchResponse = elasticsearchClient.search(searchRequest, options);
        ret = buildResponse(searchResponse, elasticsearchClient);
    } catch (IOException e) {
        Log.debug("PagePerformanceServiceImpl.findByUrl() 错误: " + e.getMessage());
    }

    return ret;
}

private <T> List<T> buildResponse(SearchResponse searchResponse, RestHighLevelClient client) {

    List<T> ret = new ArrayList<T>();

    searchResponse.getHits().forEach(item -> {
        GetRequest getRequest = new GetRequest(item.getIndex(), item.getType(), item.getId());

        try {
            GetResponse getResponse = client.get(getRequest, RequestOptions.DEFAULT);
            if (getResponse.isExists())
                ret.add(objectMapper.readValue(getResponse.getSourceAsString(), new TypeReference<T>() {
                }));
        } catch (IOException e) {
