I am able to convert String to ObjectId like below:

Here I am updating zip code of 'address' collection, suppose you will get REST api input like below:

{  
   "id": "5b38a95eb96e09a310a21778",
   "zip":"10012"
}

Now I have to find address record based on the above mentioned id (which is an ObjectId in mongodb). I have a mongorepository for that, and using below code to find the the Address record:

@Repository
public interface AddressRepository extends MongoRepository{

@Query("{'_id': ?0}")
Address findByObjectId(ObjectId id);

}

And use this repository method in your service class, like:

    public void updateZipCode(Address addressInput){
        Address address = 
addressRepository.findByObjectId(new ObjectId(addressInput.getId()));
        //here you will get address record based on the id
    }
