java - Add projection to morphia query -
Questioning with Morphia Is it possible to limit the returned areas? (Specify the launch)?
On the command line like this:
db.Institution.find ({name: / ^ Berlin}}, {slug: 1})
or with Java driver: BasicDBObject launch = new BasicDBObject ("Slug", 1); Collection.find (new BasicDBObject (), projection);
thanks
you do, see
Pattern regex = Pattern.compile ("^ Berlin"); Query & lt; InsitutionEntity & gt; Query = mongoDataStore.find (InsactionEntity.class) .field ("name") equals (regex). Removed field (true, "slug"). AsList (); (this did not test, but it should work like this)
