使用JestClient从elasticsearch检索文档时获取Double值而不是整数

Question

使用JestClient从ElasticSearch检索文档，获取Double值而不是整数。

Index mapping -



               "makeId": {
                  "type": "integer"
               },
               "makeName": {
                  "type": "keyword"
               },
               "yearId": {
                  "type": "integer"
               }

我正在使用JestClient（在java中）获取字段值,我希望makeId和yearId的值为integer,但值返回为Double,

Jest maven Depandency-

<dependency>
   <groupId>io.searchbox</groupId>
   <artifactId>jest</artifactId>
   <version>2.0.0</version>
</dependency>

String[] reqFields = { "makeName","makeId","yearId" };
 SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder();
                    BoolQueryBuilder boolquery = QueryBuilders.boolQuery();
                    boolquery.must(QueryBuilders.matchQuery("yearId", yearId));
                    searchSourceBuilder.query(boolquery).fetchSource(reqFields, null).size(9000);

                    Search.Builder searchBuilder = new Search.Builder(searchSourceBuilder.toString()).addIndex(indexName).addType(indexType);
                    SearchResult result = jestClient.execute(searchBuilder.build());
                    List<Hit<Map, Void>> hits = result.getHits(Map.class);

SearchResult result = jestClient.execute(searchBuilder.build());

{“take”：29,“timed_out”：false,“_shards”：{“total”：5,“successed”：5,“failed”：0},“hits”：{“total”：1466,“max_score”：1.0,“hits”：[{“_index”：“vehicle”,“_type”：“vehicle_dev”,“_id”：“836”,“_score”：1.0,“_source”：{“makeID”：2,“makeName”：“buick”,“yearid”：“2012}},{”_index“：”

（预期）

但下一行执行时-

List<Hit<Map, Void>> hits = result.getHits(Map.class);

值从2改为2倍即2.0。

使用index字段创建自己的模型（POJO）类，并给出适当的类型

示例

public IndexModel
{
private integer makeId;
private String makeName;
private integer yearId;

//Generate the setter and getters 

List<IndexModel> IndexModelList = result.getSourceAsObjectList(IndexModel.class);
                for( IndexModel indexModel: IndexModelList ){
                    indexModel.getyearId();
