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

public class Item extends BaseEntity{

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

Type "it" for more

{ "v" : 1,"key" : { "a" : 1 },"name" : "a_1","ns" : "geolocation.items" }
我的数据库记录看起来像
{

"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" : {

}
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.
