Hibernate 4 uses JBoss logging rather than slf4j used in earlier versions. For log4j configuration, we need to follow below steps.
Add log4j dependencies for maven project, if not maven then add corresponding jar files.
Create log4j.xml configuration file or log4j.properties file and keep it in the classpath. You can keep file name whatever you want because we will load it in next step.
For standalone projects, use static block to configure log4j using DOMConfigurator or PropertyConfigurator. For web applications, you can use ServletContextListener to configure it.
That’s it, our setup is ready. Create org.apache.log4j.Logger instance in the java classes and start logging
