you can still use mongoTemplate to access the Collection and simply use DBCursor:

     DBCollection collection = mongoTemplate.getCollection("boundary");
     DBCursor cursor = collection.find();        
     while(cursor.hasNext()){
         DBObject obj = cursor.next();
         Object object =  obj.get("polygons");
         ..
      ...
     }
