Description
When inserting a new POJO into a collection, the _id is properly correctly generated in the document representation but the POJO ID property is not populated:
MongoCollection<Document> collection;
|
Document document = new Document(); |
collection.insertOne(document);
|
// document.get("_id") = 5a1786851ce328045c0c5276 <----- _id populated as expected after insert
|
|
|
public class Widget { |
private ObjectId id; |
|
|
public String getId() { |
return id; |
}
|
|
|
public void setId(ObjectId id) { |
this.id = id; |
}
|
|
|
}
|
|
|
MongoCollection<Widget> collection; // (PojoCodecProvider configured for automatic) |
Widget widget = new Widget(); |
collection.insertOne(widget);
|
// widget.getId() == null <----- id value still null;
|
|
|
// The ID property is properly populated when using find
|
Widget widget = collection.find(...);
|
widget.getId() == 5a1786851ce328045c0c5276 <--- id value set as expected
