Failed usage of provided ID value on document insert

[aburmakov]

Self-generated ID cannot be insert into mongo collection. System-generated ObjectID.get() is used instead of self-generatd.
Looks like problem appears after commit: 8ee33b2 ("Generate and convert id on insert if explicitly defined.", 2022-05-19)

Sample code:

@Document(collection = AcmeDocument.COLLECTION_NAME)
public class AcmeDocument implements IdDocument {
    public static final String COLLECTION_NAME = "acme";
    @MongoId
    private String id;
    private String userName;
    public AcmeDocument(String userName) {
        this.id = UUID.randomUUID().toString();
        this.userName = userName;
    }
//...
}

// usage:
AcmeDocument d = new AcmeDocument(userName);
d = acmeRepository.save(d);
log.debug("create.id: {}", d.getId());

Log output: create.id: e43afa9b-06db-4935-a94a-f76578c7af83
But mongoDb document has _Id as generated ObjectId: 6332ca654af6176f2c0c230d

I might be missing something but I cannot reproduce the issue.

class AcmeDocument {
	@MongoId
	private String id;
	private String userName;
	public MyOddIdDocument(String userName) {
		this.id = UUID.randomUUID().toString();
		this.userName = userName;
	}
}

template.dropCollection(AcmeDocument.class);

AcmeDocument source = new AcmeDocument("one");
template.save(source);

org.bson.Document dbDoc = collection.find().limit(1).cursor().next());

assertThat(dbDoc).isNotNull();
assertThat(dbDoc.get("_id")).isEqualTo(source.id);

AcmeDocument loaded = template.findOne(query(where("id").is(source.id)), AcmeDocument.class);
assertThat(loaded).isEqualTo(source);
assertThat(loaded.id).isInstanceOf(String.class);

Please take the time to provide a complete minimal sample (something that we can unzip or git clone, build, and deploy) that reproduces the problem.

@christophstrobl Hey, please take a look at referenced issue spring-projects/spring-boot#32635. It has a reproducible example and focuses on insert() method that is actually producing wrong id.
