ES GEO地理空间查询java版

一、半径范围查询

1、设置mapping,类型为geo_point

PUT /my_locations
{
   
   
  "mappings": {
   
   
    "properties": {
   
   
      "location": {
   
   
        "type": "geo_point"
      }
    }
  }
}

2、中心点查询半径内匹配点

GET /my_locations/_search
{
   
   
  "query": {
   
   
    "bool": {
   
   
      "must": {
   
   
        "match_all": {
   
   }
      },
      "filter": {
   
   
        "geo_distance": {
   
   
          "distance": "12km",
          "location": {
   
   
            "lat": 40,
            "lon": -70
          }
        }
      }
    }
  }
}

3、java 代码

......
MultiCondition.GeoDistance geo = multiCondition.getGeoDistance();
//构建半径查询 GeoDistanceQueryBuilder
GeoDistanceQueryBuilder geoDistanceQueryBuilder = QueryBuilders.geoDistanceQuery(geo.getFieldName())
        .point(geo.geoPoint.lat(),geo.geoPoint.getLon())
        .distance(geo.getDistance(), DistanceUnit.KILOMETERS)
        .geoDistance(GeoDistance.PLANE);
boolQueryBuilder.filter(geoDistanceQueryBuilder);
......
//点到圆点距离排序，返回xxkm
GeoDistanceSortBuilder geoSortBuilder = SortBuilders.geoDistanceSort(geoDistance.getFieldName(), geoDistance.geoPoint.getLat(), geoDistance.geoPoint.g
