> Key: LOG4J2-3013
> URL: https://issues.apache.org/jira/browse/LOG4J2-3013
> Project: Log4j 2
> Issue Type: Bug
> Components: Configurators, JsonTemplateLayout
> Affects Versions: 2.14.0
> Environment: log4j2 2.14.0 on Oracle JDK 14
> Reporter: expert
> Assignee: Volkan Yazici
> Priority: Major
>
> Applogozies I have to resort to creating an issue but I think it's major
> problem for users who want to use new json config.
> Could you please demostrate how to specify AdditionalField of JsonLayout in
> json config ?
> Ideally it would be good to see in documentation example of configuration for
> every type of plugin annotation (PluginBuilderAttribute, PluginElement and
> etc.)
> Unfortunatelly I couldnt'n figure out how to set additionalFields after two
> hours of heavy debugging in log4j2 sources.
