Logback on Jboss duplicates prefixes and new lines when logging

Question

I\'m working on java web project. I use Wildfly 10. I want to use it with logback. I did some configuration:

pom.xml

Answer 1

WildFly wraps both System.out and System.err in a logger. If you want to use an appender or handler that writes to either stream you need to either use the java.io.FileDescriptor.out (or err) or you need to create a logger category for stdout or stderr as well as a new console-handler to assign to the logger.

/subsystem=logging/pattern-formatter=stdout:add(pattern="%s%n")
/subsystem=logging/console-handler=stdout:add(autoflush=true, target=System.out, named-formatter=stdout, level=ALL)
/subsystem=logging/logger=stdout:add(use-parent-handlers=false, handlers=[stdout], level=ALL)

The above CLI script should remove the default pattern from the logger stdout.

The corresponding representation in standalone.xml looks like this:
