I would like to use slf4j+logback for two purposes in my application - log and audit.
For logging, I log the normal way:
static final Logger logger = LoggerFactory.getLogger(Main.class);
logger.debug("-> main()");
For Audit, I create a special named logger and log to it:
static final Logger logger = LoggerFactory.getLogger("AUDIT_LOGGER");
Object[] params =
{ new Integer(1) /* TenantID */, new Integer(10) /* UserID */, msg};
logger.info("{}|{}|{}", params);
logback configuration:
<logger name="AUDIT_LOGGER" level="info">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS}|%msg%n
</pattern>
</encoder>
</appender>
</logger>
<root level="all">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
</pattern>
</encoder>
</appender>
</root>
Problem:
Messages logged through audit logger appear twice - once under the AUDIT_LOGGER and once under the root logger.
14:41:57.975 [main] DEBUG com.gammay.example.Main - - main()
14:41:57.978|1|10|welcome to main
14:41:57.978 [main] INFO AUDIT_LOGGER - 1|10|welcome to main
How can I make sure audit messages appear only once under the audit logger?
