> Inconsistency between Swagger Link Model and actual response

>
> Key: NIFIREG-248
> URL: https://issues.apache.org/jira/browse/NIFIREG-248
> Project: NiFi Registry
> Issue Type: Bug
> Affects Versions: 0.1.0, 0.2.0, 0.3.0
> Reporter: Kevin Doran
> Assignee: Bryan Bende
> Priority: Minor
> Time Spent: 10m
> Remaining Estimate: 0h

> If using a swagger-codgen client with strict DTO json deserialization (fail
> on unknown fields), the following types of exceptions occur when retrieving
> any DTO that has a {{Link}} type field:
> {code:java}
> com.fasterxml.jackson.databind.exc.UnrecognizedPropertyException:
> Unrecognized field "href" (class com.example.swagger.client.model.Link), not
> marked as ignorable (7 known properties: "params", "title", "rel", "type",
> "uri", "uriBuilder", "rels"])

> line: 1, column: 104] (through reference chain:
> java.util.ArrayList[0]->com.example.swagger.client.model.Bucket["link"]->com.example.swagger.client.model.Link["href"])
> {code}
> The swagger client DTO's were generated based on the swagger.json definition
> from the build output.
> The root cause is that the {{Link}} type is an abstract class that has
> different fields from the concrete classes that typically get serialized. For
> example, {{Link}} does not have an {{href}} field which is included in the
> JSON. It also has some fields that are not included in the JSON such as
> {{UriBuilder}}.
> Currently the work around is permitting non existing properties for Jackson,
> although that does not create the needed href field in the response object,
> it simply avoids the runtime exception.
