Romain Manni-Bucau commented on JOHNZON-213:
--------------------------------------------
[~jinahya] the setter is needed to map from json to the object
(jsonb.fromJson), previous code works without the setter if you remove the
fromJson call. The spec says public fields are managed if I recall correctly or
it has accessors.
> Make @JsonbTypeAdapter works with accessors

> Key: JOHNZON-213
> URL: https://issues.apache.org/jira/browse/JOHNZON-213
> Project: Johnzon
> Issue Type: Bug
> Components: JSON-B
> Affects Versions: 1.1.12
> Reporter: Jin Kwon
> Priority: Major
>
> For some reasons, I need to annotate an overridden method with an
> {{@JsonbTypeAdapter}}.
> {code:java}
> class Parent<T extends ...> {
> T options;
> }
> class Child extends Parent<SomeOptions> {
> @JsonbTypeAdapter(value = SomeOptionsTypeAdapter.class)
> public SomeOptions getOptions() {
> return super.getOptions();
> }
> }
> {code}
> Now Johnzon complains.
> {code}
> javax.json.bind.JsonbException: Missing a Converter for type class
> ...Params$Options to convert the JSON String '{"..."}' . Please register a
> custom converter for it.
> Caused by: org.apache.johnzon.mapper.MapperException: Missing a Converter for
> type class ...Params$Options to convert the JSON String '{"..."}' . Please
> register a custom converter for it.
