Elasticsearch-多边形范围查询(8.x)
目录
一、字段设计
二、数据录入
三、查询语句
四、Java代码实现
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}
