I\'m Workin with Mongo using Jongo, when I do a query I receive a LinkedHashMap as result.

Iterator one = (Iterator) friends.find(query).project         


        

Answer 1

One of the com.mongodb.BasicDBObject constructors takes a Map as input. Then you just have to call the toString() on the BasicDBObject object.

Iterator one = (Iterator) friends.find(query).projection("{_id:0}").as(Object.class);
    while (one.hasNext()) {
        LinkedHashMap data= new LinkedHashMap();

        data= (LinkedHashMap) one.next();

        com.mongodb.BasicDBObject bdo = new com.mongodb.BasicDBObject(data);    
        String json = bdo.toString();
    }
