How to configure logging in Hibernate – Logback

In this tutorial, we show how to integrate Logback logging framework with Hibernate.

Tools and Technologies used in this tutorial :

  1. Hibernate 3.6.3.Final
  2. slf4j-api-1.6.1
  3. logback-core-0.9.28
  4. logback-classic-0.9.28
  5. Eclipse 3.6
  6. Maven 3.0.3

1. Get SLF4j + Logback

To use logback in Hibernate web application, you need 3 libraries :

  1. slf4j-api.jar
  2. logback-core
  3. logback-classic

File : pom.xml

<project ...>
			<id>JBoss repository</id>



		<!-- logback -->


Where is slf4j-api.jar?
The slf4j-api.jar is defined as the dependency of “hibernate-core“, so , you do not need to declare it again.

2. logback.xml

Create a “logback.xml” file and put it into your project’s classpath, see figure below :

logback hibernate

A classic “logback.xml” example.

<?xml version="1.0" encoding="UTF-8"?>

 <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
	<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
		<Pattern>%d{yyyy-MM-dd_HH:mm:ss.SSS} %-5level %logger{36} - %msg%n

 <appender name="FILE"
	<encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
	   <Pattern>%d{yyyy-MM-dd_HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n

	<rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">



  <logger name="org.hibernate.type" level="ALL" />
  <logger name="org.hibernate" level="DEBUG" />

  <root level="INFO">
	<appender-ref ref="FILE" />
	<appender-ref ref="STDOUT" />


With this logback.xml configuration, it means, redirect all your web application logging outputs to console and also a file at “c:/mkyongapp.log“.

3. Output

See logback logging output at “C:\\mkyongapp.log” below :

Is it possible to amend to files path of the log so that you create your log in src/main/resources??? I have n app that will create some logs and then interogate them. so I would like to keep my logs on the classpath


Hi Mkyong, another good tutorials 🙂

But in this current time, Hibernate 4 using jboss.logging for their logging system.

In my project, i use pure Hibernate 4 and Logback only, and it seems not produce any hibernate log.

So what is the solution?
Adding logging facade using SLF4j?

Thankyou 🙂


Hi I am not able to generate the log files….though I am able to print the output in the console, could you please explain me that
