Kevin Doran updated NIFIREG-248:
--------------------------------
Description:
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"])
at [Source:
[\{"createdTimestamp":1553517081543,"identifier":"8d27c763-26ce-4f0b-bc5d-56382bd17e15","link":{"href":"buckets/8d27c763-26ce-4f0b-bc5d-56382bd17e15","params":({"rel":"self"}},"name":"test_bucket","permissions":\{"canDelete":true,"canRead":true,"canWrite":true}}];
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 is permitting non existing properties for Jackson.
