Mongodb-mongotemplate Geo-coordinate operations

Because of the Springboot + mongotemplate used in the project, it is still necessary to mongotemplate operation mode

First create a bean:

Note:

@GeoSpatialIndexed  

using MongoDB'S Geospatial indexing feature.
Start without adding this annotation, and then calculate the distance when the error will be

1, prepare the test data:

    /** * Save*/@Test Public voidtest1 () { for(intx = -; X <131; X + +) {             for(inty = -; Y < A; y++) {Double loca[]=Newdouble[]{double.valueof (x), double.valueof (y)}; Chargepoi Chargepoi=NewChargepoi (); CHARGEPOI.SETPOI_ID ("poiid"+x); Chargepoi.setmedia_url ("http://www.baidu.com?params="+x); Chargepoi.setpoi_name ("Vini"+arrays.tostring (Loca)); Chargepoi.setprice (Math.random ()* -);                Chargepoi.setlocation (Loca);            Mongotemplate.insert (Chargepoi); }        }    }

2, circular query

    /** * Circle*/@Test Public voidtest2 () {Circle Circle=NewCircle ( -, -, -); List<ChargePoi> find = Mongotemplate.find (NewQuery (Criteria).where(" Location"). Within (circle)), Chargepoi.class); System. out. println (Find); System. out. println (Find.size ()); }

3, Star Search

    /** * Spherical*/@Test Public voidtest3 () {Circle Circle=NewCircle ( -, -, -); List<ChargePoi> find = Mongotemplate.find (NewQuery (Criteria).where(" Location"). Withinsphere (Circle)), Chargepoi.class); System. out. println (Find.size ()); System. out. println (Find); }

4, Rectangle query, Box

    /** * Box*/@Test Public voidtest4 () {Box box=NewBox (NewPoint (Ten, One),NewPoint (Ten, -)); List<ChargePoi> find =Mongotemplate.find (NewQuery (Criteria).where(" Location"). Within (box), Chargepoi.class); System. out. println (Find.size ()); System. out. println (Find); }

5, by distance from near to Meta query

    /** * near*/@Test Public voidTest5 () { point point=NewPoint ( A, A); List<ChargePoi> venues =Mongotemplate.find (NewQuery (Criteria).where(" Location"). Near (point). MaxDistance ( -)), Chargepoi.class); System. out. println (Venues.size ()); System. out. println (venues); }

6, Spatial distance query

    /** * Nearsphere*/@Test Public voidTest6 () { point point=NewPoint ( A, A); List<ChargePoi> venues =Mongotemplate.find (NewQuery (Criteria).where(" Location"). Nearsphere (Point). MaxDistance ( -)), Chargepoi.class); System. out. println (Venues.size ()); System. out. println (venues); }

7, nearest point query

    @Test    publicvoid  test7 () {        new point (12 );         = Nearquery.near (location). MaxDistance (new Distance (100000, metrics.kilometers));        Georesults<ChargePoi> result = mongotemplate.geonear (query, Chargepoi.  Class);        System.  out . println (result);    }
