Grails injects a log object for each artifact, but these loggers are not accessible within static methods.

Here’s a quick-and-dirty code snippet sample that demonstrates how to log from a static method within domain class Account. The trick is to get the Logger by invoking org.apache.commons.logging.LogFactory.getLog(this):

import org.apache.commons.logging.LogFactory

static Account createOrFindByImei(String imei)
{
    Account result = Account.findByImei(imei)
    return result ? result  :
    saved(new Account(
            imei:imei,
            email:Login.getCurrentLogin().email,
            name:"* New Account ($imei) created at " + new Date()))
}

private static Account saved(Account account)
{
    if(account.save())
    {
        return account
    }
    LogFactory.getLog(this)
      .error("!saved: $account.errors", new Throwable("*STACKTRACE*"))
}
