Hi Team , 

I saving my java object to mongo DB using proper codec and able to save object in mongo

i am using collection.insertOne(javaObject);

i have @BsonId ObjectId id in my class . when i save object to database i don't see database generated id reflecting in  ObjectId id (i see this is as null , even after saving object to DB) field of my class .

to get this DB generated Id so i have to query mongo Db one more time or there is some other way to do so ?

Could you please help with above .

Thanks..!
