I don't use Lombok, but:

https://projectlombok.org/api/lombok/extern/log4j/Log4j

says:

  Example:

  @Log4j
  public class LogExample {
  }


will generate:

  public class LogExample {
      private static final org.apache.log4j.Logger log = 
org.apache.log4j.Logger.getLogger(LogExample.class);
