嗨,我有一个带有 2d 球体索引的集合
wayCollection.createIndex(new BasicDBObject("poly", "2dsphere"));
我当我尝试插入某个对象时出现错误:
Exception in thread "main" com.mongodb.WriteConcernException: { "serverUsed" : "localhost:27017" , "ok" : 1 , "n" : 0 , "err" : "insertDocument :: caused by :: 16755 Can't extract geo keys from object, malformed geometry?: { _id: ObjectId('53a89dc6a0042baf54050037'), id: 24837452, version: \"64\", changeset: \"13731788\", uid: \"362915\", user: \"micha555\", timestamp: \"2012-11-03T09:11:23Z\", poly: { type: \"Polygon\", coordinates: [ [ [ 9.1244131, 50.0109503 ], [ 9.120464800000001, 50.0099731 ], [ 9.116641, 50.0077
虽然多面环是闭合的(第一个和最后一个坐标相同)
有任何想法吗?
这是另一个被拒绝的多边形:
{
"type":"Polygon",
"coordinates":[

}
当我把它贴在这里似乎没问题:http: //geojsonlint.com/
也许mongo db不喜欢一个点被使用两次
