Complete “Scala Logging” Example

Question

I\'m trying to use Typesafe\'s Scala Logging but couldn\'t get it to print any debug message. I expect Scala Logging to print debug message to the default screen but it does

For those who're still struggling for how to make your scala-logging work in your sbt project. They just need to follow these steps:

1. Add these two dependencies in your build.sbt:

   libraryDependencies += "com.typesafe.scala-logging" %% "scala-logging" % "3.1.0"
   libraryDependencies += "ch.qos.logback" % "logback-classic" % "1.1.2"
   

2. Create a file logback.xml in your /src/main/resources/ and paste below mentioned content in that file.

   
       
           
               %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
           
       
   
       
           
           /Users/yourusername/test.log
           false
           
               %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
           
       
   
       
           
           
       
   
   

3. Extend your Scala class or object with trait LazyLogging:

   import com.typesafe.scalalogging.slf4j.LazyLogging
   class MyClass extends LazyLogging {
     logger.debug("This is very convenient ;-)")
   }
   

4. It's done.

P.S: Only a side note that logger is already a member of trait LazyLogging so you don't need to create it (as shown in above example)
