How to specify log4j configuration in spring application?

java, spring Add comments

If you do not want to store your log4j configuration in your classes directory then you need to tell log4j where it can find it.

One possibility is to configure it in your applicationContext.xml as shown here

<bean id="log4jInitialization"
 class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
   <property name="targetClass"
      value="org.springframework.util.Log4jConfigurer" />
   <property name="targetMethod" value="initLogging" />
   <property name="arguments">
      <list>
         <value>conf/log4j.xml</value>
      </list>
   </property>
</bean>

If you are running your web application as an expanded war then another option is to use a listener in your web.xml. This will only work on an unexpanded war.

<context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>/WEB-INF/resources/log4j.properties</param-value>
</context-param>
<context-param>
    <param-name>log4jRefreshInterval</param-name>
    <param-value>1000</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

While using the second approach I am getting the below exception.

That method will not work on an unexpanded war.
Have updated the post.

Looks like its failing to find log4j class(es). Where is your log4j jar?

You have to copy logg4j library in the application server libraries
