在spring

如果要防止两次调用elasticsearch，我建议编写一个自定义的ResultsExtractor：

SearchQuery searchQuery = new NativeSearchQueryBuilder().withIndices(indexName)        .withTypes(typeName)        .withQuery(queryBuilder)        .withPageable(pageable)        .build();SearchResult result = template.query(searchQuery, new ResultsExtractor<SearchResult>() {    @Override    public SearchResult extract(SearchResponse response) {        long totalHits = response.getHits()     .totalHits();        List<String> ids = new ArrayList<String>();        for (SearchHit hit : response.getHits()) { if (hit != null) {     ids.add(hit.getId()); }        }        return new SearchResult(ids, totalHits);    }});System.out.println(result.getIds());System.out.println(result.getCount());

其中SearchResult是自定义类：

public class SearchResult {    List<String> ids;    long count;    //getter and setter}

这样，您可以从elasticsearch中获取所需的信息

SearchResponse

关于您的第二个问题：据我所知，在调用

queryForPage(SearchQuery query, Class<T> clazz,SearchResultMapper mapper)
