public final class MulticolorLayout extends PatternLayout
Use it in your LOG4J configuration:
log4j.rootLogger=INFO, CONSOLE log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender log4j.appender.CONSOLE.layout=com.jcabi.log.MulticolorLayout log4j.appender.CONSOLE.layout.ConversionPattern=[%color{%-5p}] %c: %m%n
The part of the message wrapped with %color{...}
will change its color according to the logging level of the event. Without
this highlighting the behavior of the layout is identical to
PatternLayout
. You can use %color-red{...}
if you
want to use specifically red color for the wrapped piece of text. Supported
colors are: red
, blue
, yellow
, cyan
,
black
, and white
.
Besides that you can specify any ANSI color you like with
%color-<attr>;<bg>;<fg>{...}
, where
<attr>
is a binary mask of attributes,
<bg>
is a background color, and
<fg>
is a foreground color. Read more about
ANSI escape code.
