AggregateReference bug

[jacko9et]

Referring to the usage method of the document:

  @GetMapping(path = "/scanners")
  ResponseEntity<?> getProducers(
    @RequestParam AggregateReference<Producer, ProducerIdentifier> producer) {

    var identifier = producer.resolveRequiredId();
    // Alternatively
    var aggregate = producer.resolveRequiredAggregate();
  }

The following information is returned:

Source to convert from must be an instance of [java.lang.String]; instead it was a [java.net.URI]

I've created a minimal example to reproduce the issue. https://github.com/jacko9et/spring-data-rest-demo

There is no support for resolving a URI to an AggregateReference instance yet. Any reason you're not simply declaring the Producer as parameter type?

An already fully supported alternative to AggregateReference is jMolecules' Association which is essentially the same as AR, independent of Spring Data, but fully supported through automatically registered converters via the org.jmolecules.integrations:jmolecules-spring artifact.

@odrotbohm Thank you for your reply. I would like the custom controller's parameters to be able to resolve the uri to the entity to comply with hateoas usage, but it cannot be resolved automatically. I tried adding the annotation @Param or @RequestParam to the entity type, but it didn't work. Is there any arbitrary way to parse uri to entities?
