开发版本详见：Elasticsearch-经纬度查询(8.x-半径查询)_es经纬度范围查询-CSDN博客

一、字段设计

PUT /aoi_points {   "mappings": {     "properties": {       "location": {         "type": "geo_shape"       }     }   } }

aoi_points是索引名称，location是字段名称，它将存储地理形状数据

二、数据录入

POST /aoi_points/_doc {   "location": {     "type": "point",     "coordinates": [-74.0060, 40.7128]   } }

三、查询语句

GET /aoi_points/_search {   "query": {     "bool": {       "filter": {         "geo_shape": {           "location": {             "shape": {               "type": "polygon",               "coordinates": [                 [                   [-74.02, 40.715],                   [-73.99, 40.715],                   [-73.99, 40.705],                   [-74.02, 40.705],                   [-74.02, 40.715]                 ]               ]             },             "relation": "within"           }         }       }     }   } }

• location是存储地理位置的字段
• shape定义了一个多边形区域，coordinates是一个数组，包含多边形顶点的坐标
• relation指定了查询的地理空间关系，这里是within，表示查询多边形内部的点
• 多边形的坐标点需要按顺序（通常是顺时针或逆时针）排列，形成一个闭合的多边形

四、Java代码实现

具体查询对象，可自行定义，本方法只提供思路，莫直接粘贴使用

        // 封装ES查询参数         BoolQuery.Builder boolQueryBuilder = new BoolQuery.Builder();         // AOI范围查询         ShapePO shapePo =                     new ShapePO().setType(GeographyType.POLYGON.getValue()).setCoordinates(poi.getAoi().getCoordinates());         // 多边形查询         GeoShapeQuery geoShapeQuery =             GeoShapeQuery.of(geoShape -> geoShape.field(PoiIndexConstant.LOCATION)                     .shape(s -> s.shape(JsonData.fromJson(JSONUtil.toJsonStr(shapePo))).relation(GeoShapeRelation.Within)))._toQuery().geoShape();         boolQueryBuilder.filter(f -> f.geoShape(geoShapeQuery));         int size = poi.getAoi().getCoordinates().get(0).size();          SearchRequest.Builder searchRequestBuilder = new SearchRequest.Builder();         searchRequestBuilder.index(esIndexProperties.getPoiIndexRead())                 .query(query -> query.bool(boolQueryBuilder.build()))                 .size(size);          // ES查询         SearchRequest searchRequest = searchRequestBuilder.build();         log.info("getSmallAttractionByPoiId query:{}", searchRequest.toString());         SearchResponse<PoiIndex> searchResponse = esUtil.queryDocument(searchRequest, PoiIndex.class);          if (searchResponse.hits().hits().isEmpty()) {             return List.of();         }         List<SmallAttractionDTO> smallAttractionDtoList = new ArrayList<>();         for (Hit<PoiIndex> hit : searchResponse.hits().hits()) {             // 业务处理         }
