  • 0

I am trying to configure log4j for the first time but its not creating myTest.log file. Below is my log4j.properties file and location of this file is WEB-INF/classes folder.

log4j.rootLogger=INFO, stdout, com.myTest

#tomcat logger
#log4j.logger.org.apache.catalina=DEBUG

log4j.logger.com.myTest=INFO

log4j.logger.org.apache.commons.configuration.PropertiesConfiguration=DEBUG

#appenders
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%5p] %d{yyyy-MM-dd HH:mm:ss} %m%n

log4j.appender.com.myTest=org.apache.log4j.FileAppender 
log4j.appender.com.myTest.File=myTest.log 
log4j.appender.com.myTest.MaxFileSize=15MB 
log4j.appender.com.myTest.MaxBackupIndex=10 
log4j.appender.com.myTest.layout=org.apache.log4j.PatternLayout 
log4j.appender.com.myTest.layout.ConversionPattern=[%5p] %d{yyyy-MM-dd HH:mm:ss} %m%n

log4j.appender.org.apache.ibatis=org.apache.log4j.FileAppender 
log4j.appender.org.apache.ibatis.File=myTest.log 
log4j.appender.org.apache.ibatis.MaxFileSize=15MB 
log4j.appender.org.apache.ibatis.MaxBackupIndex=10 
log4j.appender.org.apache.ibatis.layout=org.apache.log4j.PatternLayout 
log4j.appender.org.apache.ibatis.layout.ConversionPattern=[%5p] %d{yyyy-MM-dd HH:mm:ss}     %m%n

My controller class is like

@Controller
public class LoginController
{
static final Logger logger = Logger.getLogger(LoginController.class);

@RequestMapping("/login")
public ModelAndView login(){

    logger.debug("Test logs");
    logger.error("test error");

    return new ModelAndView("login"); 

}

 }

But I can’t see any myTest.log file in my Apache/log folder. Is this a place it should be?

Jar file I am using is log4j-1.2.16.jar. Is anything else required.

I am using Ubuntu and its first time I am using this.

    Put log4j.properties file in build/classes/ folder.

    Put file path to ${catalina.home}/logs/myTest.log. 

      log4j.appender.com.myTest.File=${catalina.home}/log/myTest.log

    Path of logs can be checked by writing below code in your LoginController class

        Enumeration e = Logger.getRootLogger().getAllAppenders();
    while ( e.hasMoreElements() ){
      Appender app = (Appender)e.nextElement();
     if ( app instanceof FileAppender ){
    System.out.println("File: " + ((FileAppender)app).getFile());
  }

    }
