------------------------------------
Resolution: Abandoned
> POJO's field or method name containing the $ character is not serialized
> ------------------------------------------------------------------------
>
> Key: JOHNZON-307
> URL: https://issues.apache.org/jira/browse/JOHNZON-307
> Project: Johnzon
> Issue Type: Bug
> Components: Mapper
> Affects Versions: 1.1.12, 1.2.3
> Reporter: Benoit Prudhomme
> Priority: Major
> Fix For: 1.2.6
>
>
> We are building an _Open API 3.0_ generator based on
> _io.swagger.core.v3:swagger-models:2.1.1_. The features coming from the
> version 3.0 are *mandatory* for us, specially the ability to make references.
> However references use the _*$ref*_ ([Structuring a complex JSON
> schema|https://json-schema.org/understanding-json-schema/structuring.html])
> keyword in the JSON key.
> example:
> {code:java}
> "schema": {
> "$ref": "#/components/schemas/user"
> }{code}
> Since the commit bcf51d2e5b1267dcf317816b7db759460cb3c715 ([more global
> exclude rules for fields and
> methods|https://github.com/apache/johnzon/commit/bcf51d2e5b1267dcf317816b7db759460cb3c715]),
> every field or method name containing the _*$*_ is ignore and not serialized.
>
> Currently, we extended the classes:
> _com.onwbp.org.apache.johnzon.mapper.access.FieldAccessMode_
> _com.onwbp.org.apache.johnzon.mapper.access.MethodAccessMode_
> to override this behavior.
> Unfortunatly, the class
> _com.onwbp.org.apache.johnzon.mapper.access.FieldAndMethodAccessMode_ and
> every classes making direct references to them have to be forked to use our
> extensions.
> Since the _*isIgnored*_ method is _*protected*_ we though that the behavior
> could be easily overriden.
> *Can the ignore filter be fixed to allow, at least, the _$ref_ keyword ?*
> *In absence of fix, can you provide us the best way to override the ignore
> filter algorithm ?*
> Note: since _*$id*_ and _*$schema*_ are specified as well in the JSON Schema,
> they should not be filtered when present in POJO's field or method name.
