Not printing logs in console of Logger

I've removed all system.out.println() in my code, and added Logger of apache log4j. But nothing is getting printed in my console. Here is my log4j.properties file 

# Define the root logger with appender X
log4j.rootLogger = DEBUG, X

# Set the appender named X to be a File appender
log4j.appender.X=org.apache.log4j.FileAppender

# Define the layout for X appender
log4j.appender.X.layout=org.apache.log4j.PatternLayout
log4j.appender.X.layout.conversionPattern=%m%n

I'm calling logger class as follows 

Logger log = Logger.getLogger(PersonImpl.class.getName());

In addition to my log.info(), other logs are getting printed. 

DEBUG [http-bio-8080-exec-3] (Table.java:505) - No alter strings for table : hibernate_sequence
DEBUG [http-bio-8080-exec-3] (JtaPlatformInitiator.java:42) - No JtaPlatform was specified, checking resolver
DEBUG [http-bio-8080-exec-3] (JtaPlatformResolverInitiator.java:33) - No JtaPlatformResolver was specified, using default [org.hibernate.engine.transaction.jta.platform.internal.StandardJtaPlatformResolver]
DEBUG [http-bio-8080-exec-3] (StandardJtaPlatformResolver.java:101) - Could not resolve JtaPlatform, using default [org.hibernate.engine.transaction.jta.platform.internal.NoJtaPlatform]
DEBUG [http-bio-8080-exec-3] (NamedQueryRepository.java:149) - Checking 0 named HQL queries

Try This :

log4j.rootLogger=DEBUG, stdout

log4j.appender.stdout=org.apache.log4j.ConsoleAppender

log4j.appender.stdout.Target=System.out

log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

you have only added a FileAppender (this will cause logs to be written only in file) but you will also need to add a ConsoleAppender if you want logging to be done in console as well.

it can be done as follows:

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

and also add the name of appender in rootLogger,like this

log4j.rootLogger = DEBUG, X, stdout

apart from this if you want to shutdown Hibernate specific logs, you will have to do 

log4j.logger.org.hibernate=fatal or log4j.logger.org.hibernate=off

hope this helps!

Good luck!

U can print the logs in file

log4php.appender.services = LoggerAppenderDailyFile

log4php.appender.services.layout = LoggerLayoutPattern

log4php.appender.services.datePattern = Y-m-d

log4php.appender.services.file = /home/Logs_%s

log4php.appender.services.layout.ConversionPattern = "%24d{ISO8601} [%p] %F:%L %m %n"

log4php.rootLogger = debug, services

Use this code to the class at where u want to generate the logs actually.

private static final Logger LOGGER = Logger.getLogger("Class Name Where u used");
LOGGER.error ("string which u want to print");
LOGGER.info("string which u want to print");
LOGGER.warn("string which u want to print");

Use this setting I have do it in my project. It will generate your logs to console as well as logger.out to your project directory

log4j.rootLogger=INFO, FILE

# Define the file appender
log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File=logger.out
log4j.appender.FILE.MaxFileSize=1MB
log4j.appender.FILE.MaxBackupIndex=100

# Define the layout for file appender
   log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
   log4j.appender.FILE.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.conversionPattern=%m%n

Happy To Help !
