Documentation

@Stateless
package myPackage {
  public class MyEJB() {

    /**
     * This inject a logger name "myPackage.MyClass"
     * Like you write logger = LoggerFactory.getLogger(MyClass.class)
     */
    @Inject
    Logger logger;

    /**
     * And this inject logger named "SPECIFICLOGGER"
     * Like you write logger = LoggerFactory.getLogger("SPECIFICLOGGER")
     */
    @Inject
    @LoggerName("SPECIFICLOGGER")
    Logger logger;
  }
}

You can add MDC infos, like you can for example mark a specific thread

@Stateless
package myPackage {
  public class MyBoundaryEJB() {

    /**
     * This inject a logger name "myPackage.MyClass"
     * Like you write logger = LoggerFactory.getLogger(MyClass.class)
     */
    @Inject
    Logger logger;

    @LoggerMDC(key="CALL", value="EXTERN")
    public String getMessage() {
      String msg = "foo";
      // call logger method
      logger.info("call getMessage : {}", msg);
    }
  }
}

Here the method 'getMessage' is decorate by the additionnal MDC setting. if MDC settings are cascading, the previous setting is define when the method done.

<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> 
  <layout>
    <Pattern>%X{CALL} - %m%n</Pattern>
  </layout> 
</appender>

log : EXTERN - call getMessage : foo
