The Log4j 2 SLF4J Binding allows applications coded to the SLF4J API to use Log4j 2 as the implementation.
The Log4j 2 SLF4J Binding has a dependency on the Log4j 2 API as well as the SLF4J API. For more information, see Runtime Dependencies.
The SLF4J binding provided in this component cause all the SLF4J APIs to be routed to Log4j 2. Simply include the Log4j 2 SLF4J Binding jar along with the Log4j 2 jars and SLF4J API jar to cause all SLF4J logging to be handled by Log4j 2.
Use of the Log4j 2 SLF4J Binding (log4j-slf4j-impl-2.0.jar) together with the SLF4J adapter (log4j-to-slf4j-2.0.jar) should never be attempted, as it will cause events to endlessly be routed between SLF4J and Log4j 2.
