Repository Query Method - NotNull keyword not returning anything

Hi

I'm trying to create a repository query method that uses the keyword NotNull, for example

List<Wine> findByWineNameNotNull();

But it's not returning any data, but I know there's matching data and a simple mongodb query to run the following

db.wine.find({"wineName": {"$ne": null}}, {wineName: 1});

works fine and returns the expected results.

Has anybody used the NotNull (or the IsNotNull) keyword and got it to work?

Have I missed something?

Thanks in advance

Derek

Hi Derek,

have you tried setting the log level to debug? MongoQueryCreator should log the actual Mongo query created from the method.

Cheers,
Ollie

Hi Ollie

Thanks so much for the quick reply, especially on a sunday.

The output from the MongoQueryCreator was

"Created query { "wineName" : { }}"

And then there was this from the MongoTemplate

"find using query: { "wineName" : { }} fields: null for class: class com.xyz.Wine" }

Where I would've expected to see the {"$ne" : null}

Bug?

Derek

Yes, I think so. It seems MongoQueryCreator doesn't cover the NotNull case at all. Feel fre to raise bug in JIRA.

Thanks for spotting this!
