            }
        }
    }
    root {
        info("file")  
    }
}

DailyrollOver not working.According to the documentation ,I think there should be different files ( app.log.{today's_date}) .but only one file (app.log) exists.Am i missing something here?

Try this config in your any environment,

   import org.apache.log4j.DailyRollingFileAppender // import at the top of the file
   production {

    log4j = {
            appenders  {
                file name : 'loggerFile', 
                file :"/YOUR_PATH/loggerFile.log", 
                append: false, 
                layout: pattern(conversionPattern: '%d{dd-MM-yyyy HH:mm:ss} [%5p] - %m%n')
                appender new DailyRollingFileAppender(
                        name: 'dailyAppender',
                        datePattern: "'.'yyyy-MM-dd",
                        fileName: "/YOUR_PATH/loggerFile.log",
                        layout: pattern(conversionPattern: '%d{dd-MM-yyyy HH:mm:ss} [%5p] - %m%n')
            )

          }
          root {
            debug 'dailyAppender'
            error 'stdout'
            info 'dailyAppender'
          } 
    }  
}

Note :

1.you need to create the logger file at the given location like /YOUR_PATH/loggerFile.log otherwise app will throw the FileNotFound exception.

2. Separate log for date wise file will take 1 or more hour to reflect after app start.
