LogFactory is a Apache Commons Logging factory, since a different framework. You need to instanciate you logger like this:

private static final Logger LOG = Logger.getLogger(Utils.class);

Make sure you have defined this import:

import org.apache.log4j.Logger;

Spring logs are writing , where as Normal logs not writing using log4j
