Logback Basic Usage

Logger code

Use the unified interface provided by SLF4J-API (from Logback website http://logback.qos.ch/xref/chapters/introduction/HelloWorld1.html)

 Package chapters.introduction; Import Org.slf4j.Logger; Import org.slf4j.LoggerFactory;  Public class HelloWorld1 {  publicstaticvoid  main (string[] args) {    = Loggerfactory.getlogger ("Chapters.introduction.HelloWorld1");    Logger.debug ("Hello world.") );  }}
