Subject [jira] [Commented] (LOG4J2-1010) Possibility to set ThreadContext values in calls to Logger method
Date Thu, 06 Aug 2015 11:37:05 GMT

    [ https://issues.apache.org/jira/browse/LOG4J2-1010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14659863#comment-14659863
] 

Mikael Ståldal commented on LOG4J2-1010:
----------------------------------------

Thanks Ralph, this looks really interesting. I would like something like this to be added
to log4j-core. Perhaps the {{CustomMapMessage}} should allow nesting another {{Message}} as
well as a plain string?

Question: is it necessary for the properties map to be thread-safe when using {{CustomMapMessage}}?
I.e. does it really have to be {{ConcurrentHashMap}}, or would a standard {{HashMap}} be sufficient?

However, I find it annoying that I have to declare all properties ({{key1}} and {{key2}} in
the sample) in the config file.

> It would be useful to have some logging methods in the Logger interface to set ThreadContext
values for a single log message only.
> In an asynchronous environment, using ThreadContext as currently defined is not so useful
since JVM threads might not be coupled to the logical flow of the application.
