One idea could be to create a JsonMessage class that implements the org.apache.logging.log4j.message.Message

This class would handle creating the JSON strings for your objects, so your logging code would
look like this:
logger.log(new JsonMessage(myObject));

Or, if all your appenders are custom appenders, you can extract the original object from your
JsonMessage. Note: If you are using async logging the objects wrapped in the custom Message
should be immutable or your application thread may modify them while the appender is reading
them in another thread.
