java– 在spring数据mongodb中的2d球体索引

概述我正在研究mongodb的地理空间查询,我已经在mongo控制台上执行了以下查询db.items.find( { location: { $near : { $geometry: { type: 'Point', coordinates: [77.026638, 28.459497

我正在研究mongodb的地理空间查询,我已经在mongo控制台上执行了以下查询

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

但是如何使用spring数据mongodb标准编写此查询？

我尝试使用以下标准,但它无法正常工作

 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));

堆栈跟踪

我的架构是

@document(collection = "items")public class Item extends BaseEntity{    private static final long serialVersionUID = 1L;    private String itemname;    private MetadataEnum categoryname;    private List

嵌入式文件是:)

public class Location {    private List

即使我找到系统索引确保

{ "v" : 1,"key" : { "_ID" : 1 },"name" : "_ID_","ns" : "geolocation.notification" }{ "v" : 1,"ns" : "geolocation.preference" }{ "v" : 1,"ns" : "geolocation.userItemHistory" }{ "v" : 1,"ns" : "geolocation.media" }{ "v" : 1,"ns" : "geolocation.userBasedRecommendation" }{ "v" : 1,"ns" : "geolocation.users" }{ "v" : 1,"ns" : "geolocation.authenticationToken" }{ "v" : 1,"unique" : true,"key" : { "username" : 1 },"name" : "username","key" : { "email" : 1 },"name" : "email","ns" : "geolocation.userToUserHistory" }{ "v" : 1,"ns" : "geolocation.Metadata" }{ "v" : 1,"ns" : "geolocation.mongo_data_model_map" }{ "v" : 1,"key" : { "element_ID" : 1 },"name" : "element_ID_1","key" : { "long_value" : 1 },"name" : "long_value_1","ns" : "geolocation.preferenceOrder" }{ "v" : 1,"ns" : "geolocation.counter" }{ "v" : 1,"ns" : "geolocation.item" }{ "v" : 1,"key" : { "location" : "2dsphere" },"name" : "location_2dsphere","ns" : "geolocation.item","2dsphereIndexVersion" : 2 }{ "v" : 1,"ns" : "geolocation.items" }{ "v" : 1,"ns" : "geolocation.items","2dsphereIndexVersion" : 2 }Type "it" for more> it{ "v" : 1,"key" : { "a" : 1 },"name" : "a_1","ns" : "geolocation.items" }

我的数据库记录看起来像

{    "_ID" : NumberLong(46602),"_class" : "com.samepinch.domain.item.Item","itemname" : "Chandigarh","categoryname" : "TRAVELliNG","attributes" : [        "MOUNTAIN"    ],"isAccessed" : false,"imageUrl" : "0bbd8cdb-be5c-4efc-b974-c04fb1903537itemcompressed.jpg","catagoryPreference" : "BOTH","startDate" : ISODate("2015-12-09T18:30:00Z"),"endDate" : ISODate("2015-12-09T18:30:00Z"),"location" : {        "coordinates" : [            76.76641440000003,30.72642125251779        ],"type" : "Point","radius" : 8504.948210235696    },"createdDate" : ISODate("2015-12-09T10:27:42.519Z"),"updatedDate" : ISODate("2015-12-09T10:27:42.519Z")}

我已经在集合上创建了2d spheare索引,但我不知道它为什么会给我这个错误.最佳答案更改数据存储而不是：

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

至

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

我认为对于“Point”类型你有错误的数据类型.它应该只有地理坐标的经度,纬度.你不应该包括“raduis”.

检查有效GeoJsons. 总结
