Project Lombok @Log Annotation

You put the variant of @Log on your class (whichever one applies to the logging system you use); you then have a static final log field, initialized to the name of your class, which you can then use to write log statements.

There are several choices available:
@CommonsLog

Creates private static final org.apache.commons.logging.Log log = org.apache.commons.logging.LogFactory.getLog(LogExample.class);

@JBossLog

Creates private static final org.jboss.logging.Logger log = org.jboss.logging.Logger.getLogger(LogExample.class);

@Log

Creates private static final java.util.logging.Logger log = java.util.logging.Logger.getLogger(LogExample.class.getName());

@Log4j

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

@Log4j2

Creates private static final org.apache.logging.log4j.Logger log = org.apache.logging.log4j.LogManager.getLogger(LogExample.class);

@Slf4j

Creates private static final org.slf4j.Logger log = org.slf4j.LoggerFactory.getLogger(LogExample.class);

@XSlf4j

Creates private static final org.slf4j.ext.XLogger log = org.slf4j.ext.XLoggerFactory.getXLogger(LogExample.class);

By default, the topic (or name) of the logger will be the class name of the class annotated with the @Log annotation. This can be customised by specifying the topic parameter. For example: @XSlf4j(topic=”reporting”).
