chỉ số cầu 2d trong dữ liệu mùa xuân MongoDB

Question

tôi đang làm việc trên truy vấn không gian địa lý của MongoDB, tôi đã thực hiện sau đây truy vấn trên Mongo console

db.items.find(
    { 
    location: 
     { $near : 
      { 
      $geometry: { type: "Point", coordinates: [77.026638, 28.459497 ] }, 
      $maxDistance: 10000 
      } 
     } 
    } 
) 

nhưng làm thế nào tôi có thể viết truy vấn này sử dụng tiêu chuẩn dữ liệu MongoDB mùa xuân?

Tôi đã cố gắng với việc sử dụng các tiêu chí sau đây, nhưng nó không làm việc

Criteria criteria = Criteria.where("location").near(new Point(77.026638, 28.459497)).maxDistance(1000); 

     Query query = new Query(criteria); 
System.out.println(mongoTemplate.find(query, Item.class));

Thậm chí tôi thấy chỉ số hệ thống đảm bảo

My kỷ lục cơ sở dữ liệu trông giống như

} 

Tôi đã tạo ra chỉ số spheare 2d vào bộ sưu tập, nhưng tôi không biết tại sao nó là cho tôi lỗi này.

Answer 1

Thay đổi dữ liệu lưu trữ thay vì:

"location" : { 
    "coordinates" : [ 
     76.76641440000003, 
     30.72642125251779 
    ], 
    "type" : "Point", 
    "radius" : 8504.948210235696 
} 

để

"location" : { 
    "coordinates" : [ 
     76.76641440000003, 
     30.72642125251779 
    ], 
    "type" : "Point" 
} 

Tôi nghĩ rằng cho "Point" loại mà bạn có kiểu dữ liệu sai. Nó chỉ nên có kinh độ, vĩ độ cho tọa độ địa lý. Bạn không nên bao gồm "raduis".

Kiểm tra hợp lệ GeoJsons.

Answer 2

Ngay cả khi tôi gặp sự cố này. Sau rất nhiều cuộc đấu tranh tôi tìm thấy nó mà không cần sử dụng tiêu chí. Điều này dưới đây là sử dụng không sử dụng mùa xuân ... tức là. chỉ java Điều này chắc chắn sẽ giúp bạn ra ngoài

MongoClient mongoClient = new MongoClient("localhost" , 27017); 
    DB db = mongoClient.getDB("services"); 
    DBCollection collection= db.getCollection("timezone"); 
    BasicDBObject point = new BasicDBObject("type", "Point"); 
    double[] ptCordinate={lat,longi}; 
    point.put("coordinates", ptCordinate); 

    BasicDBObject query = new BasicDBObject(
     "geometry", new BasicDBObject(
      "$near", new BasicDBObject(
       "$geometry", point 
      ) 
     ) 
    ); 
    collection.findOne(query);
