Logging in Maven Spring Web Project

I have a Maven Spring Web Project in which I intend to include log4j for logging purposes. I have included log4j in pom.xml as :- <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> In the resources folder is the log4j.properties.

In am using the logger.debug to generate the logs . But it is not getting generated.I am using jdk1.7.0_75. What can be the issue ? Is there some dependency on jar files version ?

Thanks in advance.
