How do I configure Logback to print out the class name

Question

I'm using Play 2.1. I'm using the default logger play.api.Logger. I'm confused about how it works.

In my scala code, a line in class "com.myapp.tickets" in the method "getPayment()" like this

Logger.info("getTickets") 

generates a log message like this.

14:58:58.005 INFO  application play.api.LoggerLike$class info  getTickets 

My application-logger.xml pattern is

%d{HH:mm:ss.SSS} %-5level %logger %class %method  %msg%n 

The issue I have is that %logger tells me "application", %class tells me "play.api.LoggerLike$class and %method tells me "info". I know all of that. I of course want to avoid adding more cruft into the message itself (like the class name or method).

If I print out the call stack (%caller) then level 2 has what I want, but that does not seem a viable way to generate a log.

How do I configure it to output the application specific class and method, not the class and method of the logger itself?

Answer 1

%class{0} will only output the class name, so instead of:

com.something.MyClass 

You'll get:

MyClass 

This is how my pattern for logback normally looks:

%d{HH:mm:ss} [%thread] %-5p %class{0} - %m%n 

You can also add the method and the line if you are interested by doing:

%d{HH:mm:ss} [%thread] %-5p %class{0}.%method:%L - %m%n
