Using aggregation parameters with @Aggregation

Thank you for getting in touch.
Please do not feed the entire pipeline as a string. Aggregation#pipeline accepts individual stages.
Also, there is this extra $ before each parameter binding, that is pushing the reader into scanUnquotedString mode not suitable for data binding.
You may want to use something like timestamp: { $gte: ?0, $lte: ?1 } to bind the given java.time input parameter.

My bad, I did not notice the pipeline accepts multiple strings, thanks!

Thank you, that helped also, I got confused by the JavaDoc example:

  @Aggregation("{ '$group': { '_id' : '$lastname', names : { $addToSet : '$?0' } } }")
  List<PersonAggregate> groupByLastnameAnd(String property);

Maybe it is just me, but a simpler aggregation pipeline (not using the property, but actual values) in the JavaDoc might prevent someone in the future from doing the same mistake I did.

Sorry for the noise and thank you for your time.

thank you for the feedback, glad it works for you now - yeah, makes sense to revisit the documentation.
