[jira] [Commented] (LOG4J2-3082) Support external serializers (e.g., Jackson) JsonTemplateLayout
[ https://issues.apache.org/jira/browse/LOG4J2-3082?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17485902#comment-17485902 ]
Volkan Yazici commented on LOG4J2-3082:
---------------------------------------
[~doeiqts], in the meantime, you can introduce your own Jackson-based resolver as I described in LOG4J2-3298. See the relevant comment there.

> When using JsonTemplateLayout is there a way to output composite objects as JSON?
> It looks like any composite objects are output as simple strings with the value generated by the .toString() method of the Java object.
> Is there an option to output JSON instead, possibly using _org.apache.logging.log4j.core.jackson.Log4jJsonObjectMapper_ ?
> It is currently possible to do this by converting the object into a java.util.Map before supplying it to the logging framework but it would be nice if the logging framework did this out of the box if an option is turned on as it is not always possible to do this (e.g. with objects on the MDC/NDC).
> This should apply to composite objects logged from...
> # The thread context map (MDC).
> # The thread context stack (NDC).
> # Message parameters
> # anywhere else that I may have missed.
> See the differences between the two log messages generated in the attached project.
