Log4j2 Setup

Log4j2 Setup

Pre-Requisite

1.      Maven Or Jar of Log4J2

a.      http://apachemirror.wuchna.com/logging/log4j/2.12.1/apache-log4j-2.12.1-bin.zip (download jar from her)   log4j-api-2.11.2.jar,  log4j-core-2.11.2.jar

b.      Maven Dependencies:

   <dependency>

              <groupId>org.apache.logging.log4j</groupId>

              <artifactId>log4j-api</artifactId>

              <version>2.13.3</version>

       </dependency>

       < dependency>

              <groupId>org.apache.logging.log4j</groupId>

              <artifactId>log4j-core</artifactId>

              <version>2.13.3</version>

      </dependency>

2.      Log4j2.properties file with configured properly (in com.package.resource folder)

status = error

name = PropertiesConfig

property.filename = C:\\logs\\logs.log

filters = threshold

filter.threshold.type = ThresholdFilter

filter.threshold.level = debug

appenders = rolling

appender.rolling.type = RollingFile

appender.rolling.name = RollingFile

appender.rolling.fileName = ${filename}

appender.rolling.filePattern = C:\\logs\\Previous\\debug-backup-%d{MM-dd-yy-HH-mm-ss}-%i.log.gz

appender.rolling.layout.type = PatternLayout

appender.rolling.layout.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

appender.rolling.policies.type = Policies

appender.rolling.policies.time.type = TimeBasedTriggeringPolicy

appender.rolling.policies.time.interval = 1

appender.rolling.policies.time.modulate = true

appender.rolling.policies.size.type = SizeBasedTriggeringPolicy

appender.rolling.policies.size.size=10MB

appender.rolling.strategy.type = DefaultRolloverStrategy

appender.rolling.strategy.max = 20

loggers = rolling

#Make sure to change the package structure as per your application

logger.rolling.name = javascientist.Log4JImpl

logger.rolling.level = debug

logger.rolling.additivity = true

logger.rolling.appenderRef.rolling.ref = RollingFile

 

 

 

 

3.      Java Code with Log4j2 Implementation:

package javascientist.Log4JImpl;

 

import org.apache.logging.log4j.LogManager;

import org.apache.logging.log4j.Logger;

public class App

{

       private static final Logger LOG = LogManager.getLogger(App.class);

      

       public void logMethod() {

              System.out.println("Start Method");

              LOG.debug("DEBUG LOG");

              LOG.info("INFO LOG");

              LOG.error("ERROR LOG");

              LOG.warn("WARN LOG");

              LOG.fatal("FATAL LOG");

       }

    public static void main( String[] args )

    {

        System.out.println( "Hello World!" );

        App app = new App();

        app.logMethod();

    }

}
